OSRS Defensive Magic Splashing: Train Defence Without Melee or Ranged XP

Game screenshots and facts are cited from the Old School RuneScape Wiki (strategy, equipment, drops, and related pages). Writing is original editorial, not a copy of the wiki article.

Defence is one of the most important combat skills in Old School RuneScape, but training it usually means gaining experience in Attack, Strength, Ranged, or Hitpoints at the same time. For players building pures, skillers, or accounts with strict build requirements, that collateral XP can ruin a carefully planned account. Defensive magic splashing offers a workaround: by casting combat spells on the Defensive attack style and deliberately missing (splashing) against low-level monsters, you can gain Defence experience without any Melee, Ranged, Magic, or Hitpoints XP. This guide covers how the method works, which spells and targets to use, the gear you need to guarantee splashes, and what to realistically expect from the grind.

While it is not a fast training method, defensive magic splashing has a dedicated niche. It is fully AFK-able for up to 20 minutes at a time, requires no food or prayer potions, and can be done on a low-level account with minimal supplies. Whether you are preparing a pure for a specific PK bracket or simply want to level Defence without touching your offensive stats, this technique deserves a place in your training toolkit.

Who This Is For & Requirements

Defensive magic splashing is best suited for players who want to increase Defence without gaining experience in any other combat skill. This includes pures (especially 1 Attack/1 Strength builds), skillers who avoid all combat, and Ironmen who need Defence for quests or equipment but don't want to risk unwanted XP. The method is also used by players who simply want an extremely AFK way to train Defence while working or studying.

Before you start, you need to meet the following requirements:

How Defensive Casting and Splashing Actually Works

In Old School RuneScape, combat experience is awarded based on the attack style you have selected. For Magic, casting a combat spell normally gives Magic experience. However, if you set your attack style to Defensive (also called "Defence" in some interfaces), the base Magic experience from the cast is converted into Defence experience instead. This base experience is a fixed amount per cast, independent of whether you hit or miss.

When a spell "splashes," it means you miss your target entirely. You still receive the base Defence experience for the cast, but you do not receive the additional experience that would normally come from dealing damage. Since no damage is dealt, you also gain no Hitpoints experience and the monster's health never drops, so it can be used indefinitely as a training dummy.

To splash consistently, your Magic accuracy must be lower than the monster's Magic defence roll. According to the Magic skill mechanics, a monster's Magic defence roll is based almost entirely on its Magic level and Magic defence bonus—its Defence level is irrelevant (with a few exceptions like Verzik Vitur and the ice demon). This means you can splash on low-level monsters even though they have low Defence, as long as you tank your own Magic attack bonus low enough. Wearing heavy melee armour reduces Magic attack significantly, often to -65 or lower, which makes you miss almost every time against low-Magic creatures.

It is important to note that elemental weaknesses can affect accuracy: if the target is weak to your spell's element, you gain bonus accuracy and damage, which could cause you to hit. Avoid using a spell that matches the monster's elemental weakness; instead, use a neutral element or one the monster is not weak to.

Spell Selection for Defensive Splashing

The strike spells from the standard spellbook are the go-to for defensive splashing because they have low requirements, cheap runes, and can be autocast with basic staves. Higher tier spells give more base Defence XP per cast, but they cost more runes and require a higher Magic level. The table below compares the common strike spells: Wind Strike, Water Strike, Earth Strike, and Fire Strike. Exact base XP values and rune costs can be found on the wiki, but the progression is clear: each higher tier offers more Defence XP per cast at a higher rune cost.

Spell	Magic Level	Runes (with staff)	Runes (without staff)	Notes
Wind Strike	1	1 Mind	1 Air + 1 Mind	Cheapest, lowest XP, can be autocast with normal staff
Water Strike	5	1 Mind	1 Water + 1 Mind	Slight XP increase, still very cheap
Earth Strike	9	1 Mind	1 Earth + 1 Mind	Mid-tier option
Fire Strike	13	1 Mind	1 Fire + 1 Mind	Highest strike spell, most XP per cast, still economical

For most players, Fire Strike is the best balance between cost and XP rate, only requiring level 13 Magic. However, if you want to keep costs to an absolute minimum or are starting fresh, Wind Strike works fine. Remember that using an elemental staff matching your spell removes the need for that elemental rune, which significantly reduces the ongoing cost.

Choosing Your Splash Target

The ideal target for defensive splashing is a monster that is low level, non-aggressive, has a relatively low Magic level (so you can easily out-miss it with negative Magic attack), and is located somewhere safe where you won't be attacked by other players or monsters. Popular choices include:

• Seagulls at Port Sarim or Corsair Cove: extremely weak, never fight back, and are often used by pures.
• Rats in Lumbridge or Varrock sewers: low level, plentiful, and safe.
• Chickens in Lumbridge or Falador farm: low level, but have almost no magic defence, so you must ensure your Magic attack is sufficiently negative.
• Cows in Lumbridge or Falador: slightly higher level, but still safe if you splash; watch out for their low combat damage if you accidentally hit.

Because splashing relies on misses, you do not need a monster with high magic defence. In fact, lower magic defence is fine as long as your own Magic attack is negative enough. Check your hit chance by casting a few spells and observing if any hits occur. If you ever deal damage, lower your Magic attack further by adding more melee armour pieces.

Gear Setup to Guarantee Misses

The key to successful defensive splashing is achieving a very low (negative) Magic attack bonus. Your Magic accuracy roll depends on your Magic level and Magic attack bonus; by wearing full melee armour, you can push the bonus to -65 or lower, making even a level 1 Magic attack roll extremely poor against almost any monster.

A typical splashing outfit includes:

• Helmet: Full helm (e.g., rune full helm, -6 Magic attack)
• Body: Platebody (e.g., rune platebody, -30 Magic attack)
• Legs: Platelegs (e.g., rune platelegs, -21 Magic attack)
• Shield: Kiteshield (e.g., rune kiteshield, -8 Magic attack)
• Gloves, boots, and cape: any melee-oriented options that reduce Magic attack further, such as leather gloves, leather boots, and any cape (capes give no magic attack but don't hurt).
• Weapon: your autocast staff, which typically gives +10 Magic attack; this is offset by the armour negatives.

With a rune full helm, platebody, platelegs, and kiteshield, you already have -65 Magic attack before the staff's +10, leaving you at -55. Adding leather gloves (-2? some gloves give negative) and boots (-1?) can get you to -58 or lower. Many players find that -65 or lower guarantees splashes against seagulls and rats. If you are still hitting, try a dragon or barrows melee armour set for even more negative Magic attack, or train your Magic level lower if possible.

Method Comparison: Splashing vs. Traditional Defence Training

Defensive magic splashing is an extreme AFK method, but it is also extremely slow. The base Defence XP per cast is small, and you gain no damage-based XP, so your hourly XP rate will be a fraction of what you could get by training Defence through normal combat. The table below compares the main approaches to Defence training in terms of attention required, XP rate, cost, and purity of XP.

Method	Attention	Defence XP/hr	Cost	Collateral XP	AFK Potential
Defensive magic splashing	Very low (check every 20 min)	Very low	Low (runes only)	None (Defence only)	Excellent
Melee training on crabs	Low to moderate	Moderate to high	Low (food/armour)	Attack/Strength/Hitpoints depending on style	Good if using aggressive monsters
Ranged training with darts	Moderate	Moderate	Moderate (darts)	Ranged/Hitpoints	Somewhat AFK
Magic training with burst spells	High	High	High (runes)	Magic/Hitpoints	Low

As you can see, splashing trades speed for absolute purity and AFK-ability. For players who only need a few Defence levels for equipment or quests and have plenty of time, it is a viable option. For everyone else, normal training is dramatically faster, but it will add unwanted XP to other skills.

Common Mistakes to Avoid

• Forgetting to select the Defensive attack style. If you autocast on Accurate or Longrange, you will gain Magic XP instead of Defence XP. Always double-check your combat settings before starting.
• Using a spell that matches the target's elemental weakness. This grants bonus accuracy and damage, making you more likely to hit and accidentally gain Hitpoints XP.
• Not having enough runes for a long AFK session. Autocasting will stop when you run out of runes, and you will stop attacking. Bring a large stack of mind runes (and use an elemental staff to avoid needing elemental runes).
• Wearing any positive Magic attack gear. Amulets of magic, wizard hats, or even a god cape can push your accuracy high enough to hit low-level monsters. Stick to full melee armour.
• Choosing a target that is aggressive or in a multi-combat zone. If the monster fights back, you may need food or take damage, ruining the AFK nature. Also avoid areas where other players might attack you (e.g., Wilderness).
• Assuming you are splashing without testing. Spend a few minutes watching your casts before going AFK. If you see any hits, adjust your gear or switch target.

Time, Cost, and the Honest Shortcut

Defensive magic splashing is a marathon, not a sprint. Even with the highest tier strike spell, the hourly Defence XP is so low that reaching level 70 Defence from 1 would take hundreds of hours of splashing. The exact time depends on your spell, cast speed, and whether you stay logged in consistently. Runes themselves are cheap, especially when using an elemental staff to eliminate elemental rune costs; a single nature rune can buy many mind runes. Still, the real cost is your time.

For most accounts, training Defence normally through melee or ranged is vastly more efficient. If you are not concerned about collateral XP, splashing is objectively a poor use of time. However, if you are building a pure or a restricted account and absolutely must avoid other XP, splashing may be your only true AFK option. For a different perspective on expensive Magic training, check out our Stun-Alching guide.

At this point, many players consider shortcuts. Buying OSRS gold can fund better gear and runes, but it won't speed up the splashing process itself. A more direct alternative is to purchase a Defence training service or even a pre-built account with the Defence level you need. These services are not against the rules if you use a reputable marketplace, and they can save you dozens or hundreds of hours of splashing. If you value your time more than the organic grind, exploring these options is an honest decision, not cheating.

Practical Next Steps

1. Decide on your goal Defence level and whether you truly need to avoid all other XP.
2. Choose a spell (Fire Strike if you have 13 Magic, otherwise Wind Strike) and buy a matching staff plus a large stack of mind runes.
3. Gather your negative Magic attack gear: full helm, platebody, platelegs, kiteshield, gloves, boots. Aim for at least -55 Magic attack after the staff bonus.
4. Travel to a safe location with low-level monsters (seagulls at Port Sarim are a classic).
5. Set your autocast to the chosen spell and your attack style to Defensive.
6. Test for a few minutes: confirm that every cast splashes and no damage is dealt.
7. Once confirmed, click once and let the autocast run. Interact with the client every 20 minutes to stay logged in. Check rune count periodically.
8. As you level up, reassess whether the XP rate is acceptable. If not, consider alternative training or a service shortcut.
