How To Splash In OSRS: The Ultimate AFK Magic Training Guide

Splashing in Old School RuneScape is an ultra-passive Magic training method achieved by reducing your Magic attack bonus to negative sixty-four or lower, guaranteeing your spells always miss while still awarding full base casting experience. By utilizing Auto-Retaliate against a low-level NPC in a single-way combat zone, you can train your Magic level continuously with minimal interaction, requiring only one manual input every twenty minutes to bypass the idle logout timer. This guide details the mechanical requirements, gear setups, optimal locations, and spell progressions to maximize your low-effort experience gains.

Mechanical Foundations & Equipment Prerequisites

Before attempting to splash, you must understand the underlying math governing Old School RuneScape combat calculations. The game determines accuracy by comparing your Magic attack bonus against your target's Magic defence. When your Magic attack bonus reaches negative sixty-four or lower, the game's accuracy algorithm rounds your chance to hit down to absolute zero.

Because you cannot land a successful hit, your spell is guaranteed to splash, dealing zero damage. This preserves your target indefinitely while ensuring you receive the fixed base experience points associated with casting the spell.

To achieve this state, you must offset the inherent magic bonuses of your staff and magical stats by wearing heavy metal armor, which carries severe negative Magic attack penalties.

Pre-Splashing Checklist & Technical Benchmarks

• Target Metric: Your character's Magic attack bonus must display as negative sixty-four (-64) or lower in your Equipment Stats interface.
• Auto-Retaliate Setting: Must be toggled to ON in your Combat Options interface to ensure your character automatically casts back when attacked.
• Account Requirements: Level 1 Magic for basic Strike spells. Level 40 Ranged is highly recommended for P2P accounts to equip Green d'hide vambraces, though alternative low-level setups exist.
• Mandatory Inventory Items: Selected elemental staff (to eliminate the cost of basic elemental runes), thousands of Mind, Chaos, Death, or Blood runes depending on your level, and a Rune Pouch if available to conserve inventory space.
• Session Duration Limit: Twenty minutes of continuous, hands-free combat before the game's idle detection system stops your auto-attacks.

Step-by-Step Splashing Setup & Execution

Step 1: Assembling the Negative-Sixty-Four Magic Gear

To hit the magic threshold of negative sixty-four, you need to combine heavy plate armor with specific ranged armor components that penalize your magical accuracy.

For standard accounts, buy the following items from the Grand Exchange or specialty armor shops:

• Full Helmet: Bronze, Iron, Steel, Black, Mithril, Adamant, or Rune Full Helm (-6 Magic Attack)
• Platebody: Bronze, Iron, Steel, Black, Mithril, Adamant, or Rune Platebody (-30 Magic Attack)
• Platelegs or Plateskirt: Bronze, Iron, Steel, Black, Mithril, Adamant, or Rune Platelegs (-21 Magic Attack)
• Kiteshield: Bronze, Iron, Steel, Black, Mithril, Adamant, or Rune Kiteshield (-8 Magic Attack)

This base armor combination provides a negative sixty-five (-65) Magic attack bonus, which is sufficient if you are not wielding a staff. However, wielding an elemental staff adds a positive four (+4) Magic attack bonus, raising your total to negative sixty-one (-61). To correct this and keep your staff equipped, you must apply one of the following secondary adjustments:

• Option A (Requires 40 Ranged): Equip Green Dragonhide Vambraces in your glove slot. These provide a negative ten (-10) Magic attack bonus, bringing your net total with a staff to negative seventy-one (-71).
• Option B (Low Ranged alternative): Purchase a Cursed Goblin Staff from Diango in Draynor Village. This weapon provides zero (+0) Magic attack bonus, meaning you can wear standard metal armor without needing vambraces. Note that this staff does not provide unlimited elemental runes.
• Option C (F2P/Low Level alternative): Equip leather boots for a negative three (-3) Magic attack bonus alongside your metal armor, bringing your total to exactly negative sixty-four (-64).

Pro-Tip: Double-check your character's equipment bonus screen before leaving the bank. If your Magic attack bonus is exactly negative sixty-three (-63), you will occasionally land a successful hit, deal damage, kill your target, and stop training.

Step 2: Selecting Your Autofire Spell and Runes

Open your Magic Spellbook and locate the combat spell you wish to use. Right-click the spell and select "Autocast," then choose your equipped elemental staff to link the spell.

• Wind spells require an Staff of Air to eliminate air rune costs.
• Fire spells require a Staff of Fire to eliminate fire rune costs.

Stock your inventory with the required catalyst runes. Mind runes are used for Strike spells, Chaos runes for Bolt spells, Death runes for Blast spells, and Blood runes for Wave spells. Purchase at least twelve hundred (1,200) casts per hour of planned training, as combat spells in Old School RuneScape cast at a fixed rate of five game ticks (exactly three seconds per cast).

Step 3: Traveling to a Safe, Active Splashing Location

You cannot splash in Lumbridge or its immediate surrounding castle grounds. In 2014, Jagex updated the game to prevent players from receiving Magic experience when splashing in Lumbridge to prevent world clutter for new players.

Travel to one of these verified splashing hot spots:

• Port Sarim Seagulls: Travel to the docks of Port Sarim. The seagulls have low combat stats, do not deal damage, and are isolated from heavy foot traffic.
• Varrock Sewers Rats: Descend into the manhole east of the Varrock palace. The rats in the entry corridor are ideal, passive targets.
• Ardougne Zoo: For members, casting spells on the caged animals inside the Ardougne Zoo provides a safe zone where other players cannot attack your target or lure it away.
• Ferox Enclave: The sheep outside the enclave in the Wilderness transition zone are excellent targets for low-level accounts, though you must stay alert to player-versus-player boundaries.

Step 4: Initiating Combat and Managing the Idle Loop

Locate your target NPC. Ensure your combat options are set to Auto-Retaliate. Cast your chosen spell manually on the target once to initiate combat. Once the target attacks you, your character will enter a defensive loop, automatically casting your selected spell every three seconds.

Warning: To prevent players from training completely while sleeping or away from their computers, Jagex implemented a twenty-minute idle combat timer. If you do not click the screen, rotate the camera, or perform an in-game action for twenty minutes, your character will stop retaliating and eventually log out, ending your training session. You must interact with the client at least once every nineteen minutes to maintain continuous training.

Spell Progression, Costs, and Experience Metrics

The following data table outlines the optimal magic progression path for splashing. Experience rates are calculated assuming continuous casting at the maximum physical rate of twelve hundred (1,200) casts per hour.

Troubleshooting Splashing Failures

Target NPC Dies Unexpectedly

• Root Cause: Your Magic attack bonus is not negative sixty-four (-64) or lower. If you hit even a single positive number, your spell can roll accuracy, inflict damage, and kill your target.
• Actionable Fix: Open your character's equipment interface. Verify that you have not equipped a ring, amulet, or cape that provides positive Magic attack. If your bonus is negative sixty-three (-63) or higher, equip leather boots, green d'hide vambraces, or replace your elemental staff with a Cursed Goblin Staff.

Character Logs Out After Ten Minutes

• Root Cause: You are splashing in a player-versus-player (PvP) world or a specialized minigame area where alternate log-out timers apply, or you are not being actively hit back by your target.
• Actionable Fix: Ensure your target is actively attacking you and dealing zero-damage physical hits. If you are casting at a target that cannot attack you back (such as a caged animal), your character is not in active combat defense, triggering the standard five-minute idle logout timer instead of the twenty-minute combat timer.

No Experience Points Awarded Upon Casting

• Root Cause: You are standing within the restricted Lumbridge zone. Jagex completely disabled Magic experience points earned from splashed spells in this region.
• Actionable Fix: Walk away from Lumbridge. Relocate your character to Port Sarim, the Varrock Sewers, or the Falador farm chicken pens to restore your experience gains.

Another Player Steals Your Target NPC

• Root Cause: You are splashing in a multi-combat area or on an NPC that can be easily targeted by other players, such as chickens or rats in highly populated areas.
• Actionable Fix: Move to a single-combat zone. In single-combat areas, once an NPC attacks you, other players cannot attack it or intervene, securing your training spot indefinitely.

Frequently Asked Questions

Can you get banned for splashing in Old School RuneScape?

No, splashing is a completely legal, developer-accepted game mechanic. However, using third-party software, autoclickers, or physical weights on your keyboard to bypass the twenty-minute logout timer is a violation of the Rules of RuneScape and will result in a ban for macroing.

Can F2P accounts splash successfully?

Yes, Free-to-Play accounts can easily splash by wearing a full set of bronze, iron, or steel plate armor, a kiteshield, and leather boots to hit the negative sixty-four Magic attack threshold. F2P players commonly use Wind Strike or Fire Strike on rats in the Varrock Sewers.

Does my Magic level affect my splashing success?

No, your Magic level only unlocks higher-tier spells and increases your maximum damage potential when wearing standard gear. Because your Magic attack bonus is kept at negative sixty-four or lower, your accuracy remains locked at zero percent, regardless of how high your Magic level grows.

Why can't I splash on spiders in the Lumbridge Castle cellar?

The Lumbridge Castle cellar is part of the Lumbridge restricted zone. Jagex disabled splashing experience across the entire Lumbridge area to ensure that new players entering the game are not greeted by worlds cluttered with inactive, splashing characters.
