Different magic goals require different spell and gear choices. Start with your objective to find the optimal configuration.

Boss Killing (Powered Staves)

Tumeken's Shadow dominates boss DPS with its triple magic damage bonus. Sanguinesti Staff provides healing. Trident of the Swamp is the budget option.

AoE Slayer (Ancient Magicks)

Ice Barrage and Blood Barrage are essential for multi-target Slayer tasks like Nechryaels, Dust Devils, and Smoke Devils. Base 29-30 damage + equipment bonuses.

PvP Magic Damage

In PvP, Fire Surge with Tome of Fire (+50% damage) and full Magic Damage % gear can achieve 48+ max hit. Ice Barrage is used for its freeze effect + damage.

Budget Magic Training

Fire Bolt with Chaos Gauntlets is a classic budget option. Higher spells cost more runes but deal more damage. Calculate cost per damage to find optimal training spells.

Raid Magic Setups

Tumeken's Shadow at CoX/ToB provides the highest magic DPS. The calculator helps compare it to Sanguinesti Staff and Trident for different raid boss defence values.

Maximum Possible Magic Hit

Fire Surge + Tome of Fire (+50%) + Occult (+10%) + Ancestral (+6%) + Tormented (+5%) + God Cape (+2%) + Slayer Helm (+15%) = theoretical max of 48+ damage.

Occult Necklace (+10%)

The single most impactful Magic Damage item. +10% damage to all spells. Costs ~500K GP — the best value magic damage upgrade in the game.

Ancestral Robes (+6% Full Set)

2% per piece (hat, top, bottom). Full set costs ~80M GP total. Adds +6% damage on top of other bonuses. BiS for mage DPS.

Tormented Bracelet (+5%)

Zenyte jewellery providing +5% Magic Damage. One of the largest single-slot damage bonuses. Costs ~12M GP.

Imbued God Cape (+2%)

From the Mage Arena II miniquest. Free +2% magic damage. Always use for any magic combat setup.

Tome of Fire (+50% for Fire Spells Only)

Massive +50% damage boost but only for fire spells. Transforms Fire Surge from 24 base to 36 base damage. Uses Burnt Pages as charges.

Tumeken's Shadow (Triple Bonus)

Triples your magic attack and magic damage bonuses from other equipment. This unique effect makes it the strongest magic weapon by far.

Standard Spell Base Damage

Each spell tier has a fixed base damage: Strike (2-8), Bolt (9-12), Blast (13-16), Wave (17-20), Surge (21-24). Higher tiers require higher Magic levels and costlier runes.

Ancient Magicks Base Damage

Ancients range from 13 (Rush) to 30 (Ice Barrage). Barrage spells hit all targets in a 3×3 area, making them ideal for Slayer despite lower per-target damage.

Powered Staff Scaling

Powered staves scale with Magic level. Trident max hit = Base + floor((Magic Level - 75) / 3). At 99 Magic, Trident of Swamp hits 33, Tumeken's Shadow hits 39+.

Magic Damage % Calculation

Final Max Hit = floor(Base × (1 + Total Dmg% / 100)). With +23% equipment bonus, a 24-damage Fire Surge becomes floor(24 × 1.23) = 29.

Tome of Fire Interaction

Tome of Fire adds +50% to fire spells BEFORE other equipment bonuses. Fire Surge: 24 × 1.50 = 36 base, then × 1.23 = 44 final. This makes fire spells the strongest standard magic option.

Slayer Helm / Salve on Magic

Slayer Helm (i) adds +15% magic damage on task. Salve Amulet (ei) adds +20% against undead. Applied AFTER equipment damage bonuses as a final multiplier.

Standard Spellbook Training

Use the calculator to find which spell tier gives the best damage for your Magic level. Upgrading from Blast to Wave spells adds 4 base damage — worth the extra rune cost.

Ancient Magicks for Slayer

Ice Barrage (30 damage) vs Blood Barrage (29 damage + healing). Compare max hits with your equipment to decide between freeze utility and sustain.

Powered Staves at Bosses

Tumeken's Shadow vs Sanguinesti Staff vs Trident: the level-scaling difference means 6-15 max hit gap depending on your Magic level and equipment bonuses.

PvP Fire Surge Setups

Fire Surge + Tome of Fire + Occult + Ancestral = 48+ max hit. This is competitive with melee KO potential and can be followed by an AGS spec for devastating combos.

Budget vs BiS Magic

Trident of the Seas (free charges) vs Trident of the Swamp (+3 max hit, costs Zulrah scales) vs Sanguinesti Staff (+1 max hit, healing, costs blood runes). Calculate to find your cost-effective option.

Magic Damage % Increases Max Hit

Equipment with Magic Damage % (Occult, Ancestral) directly increases your maximum hit. This is the primary way to increase magic damage output.

Magic Attack Bonus Increases Accuracy

Higher magic attack bonus improves your chance of hitting but doesn't change max hit. Against low-defence targets, extra accuracy is wasted — focus on damage.

When Accuracy Matters More

Against high magic-defence bosses (Cerberus, Grotesque Guardians), accuracy can be the limiting factor. Augury prayer (+25% magic accuracy) becomes more valuable than pure damage % gear.

When Damage Matters More

Against low-defence targets (Slayer tasks, trash mobs), you hit almost every time. Stacking Magic Damage % gives more effective DPS improvement than additional accuracy.

Tumeken's Shadow Advantage

Tumeken's Shadow triples both magic attack AND magic damage from other equipment, making it dominant in both accuracy and damage. This is why it outperforms all other magic weapons.

• Always wear Occult Necklace — +10% damage for 500K GP. The best value magic upgrade.
• Use Imbued God Cape — Free +2% from Mage Arena II. Never skip this.
• Stack all damage % equipment — Occult + Ancestral + Tormented + God Cape = +23% total.
• Use Tome of Fire for fire spells — +50% damage bonus makes fire spells hit harder than any other standard spell.
• Boost with Imbued/Saturated Heart — Higher Magic level increases powered staff max hit directly.
• Toggle Slayer Helm on task — +15% magic damage is a massive multiplier on Slayer assignments.

• Using Tome of Fire with non-fire spells — The +50% bonus ONLY applies to fire spells. No benefit for Ice Barrage or powered staves.
• Forgetting Occult Necklace — +10% damage is too impactful to skip. It should be worn for all offensive magic.
• Stacking Slayer Helm with Salve — They don't stack in-game. Use whichever gives the higher bonus.
• Ignoring powered staff level scaling — At 85 Magic vs 99 Magic, you lose ~5 max hit on powered staves. Boost with potions.
• Comparing base damage without equipment — Always compare with your actual gear to see real max hit differences.
• Using magic without damage % gear — Base spell damage is low. Equipment bonuses are what make magic competitive with melee and ranged.
• Forgetting Augury prayer — +25% magic accuracy matters significantly against high-defence targets.

Tumeken's Shadow Triple Effect

Tumeken's Shadow triples all magic attack and magic damage bonuses from other equipment. With +23% damage from gear, you effectively get +69% magic damage — plus its own high base damage.

Harmonised Nightmare Staff Speed

The Harmonised Nightmare Staff casts standard spells at 4-tick speed instead of 5 ticks. This is a 25% DPS increase from speed alone, making Fire Surge competitive with powered staves.

Ice Barrage Multi-Target Efficiency

Ice Barrage hits all targets in a 3×3 area. Against stacked Slayer targets (Dust Devils, Nechryaels), effective DPS is multiplied by number of targets. A 30 max hit against 8 targets = 240 effective damage per cast.

Blood Spell Healing

Blood spells heal 25% of damage dealt. Blood Barrage with 35 max hit heals up to 8 HP per cast. This sustain reduces food usage significantly during extended encounters.

Trident Scaling Formula

Trident max = base + floor((visible Magic Level - 75) / 3). Every 3 Magic levels = +1 max hit. Imbued Heart's +10 Magic = +3 max hit on Trident-class weapons.

Charge Spell Effect

The Charge spell from the Standard Spellbook increases God Spell (Claws of Guthix, Flames of Zamorak, Saradomin Strike) max hit from 20 to 30 for 7 minutes.
