Magic Damage

There are various methods by which players can increase their potential maximum magic damage. The effects of most equipped items can be seen at the bottom of the stats window (labelled Magic Damage: +x%), however not all boosting items are shown there. Temporarily increasing your magic level also increases your max hit (by 3% per level boosted), this boost isn't shown in the stats window either.

Currently it is not fully understood how the bonus damage is calculated. While the conventional method is to simply increase a spell's maximum hit by the total damage modifier, this has been shown on numerous occasions to be inaccurate. Players who wish to contribute information or constructive ideas are encouraged to do so on this article's discussion page.

Damage-boosting Equipment

 * It is important to note that items with a magic attack bonus such as the Third age mage hat don't boost your max hit, just your accuracy. Similarly, items with a magic defence bonus, such as the black d'hide body don't affect the maximum damage you will take from spells, just your opponent's accuracy. The only exception to this is when the hit is greater than 200 and the Magic Absorption is added into calculations.
 * A full set of void knight armour won't raise your max hit, only your accuracy.

Damage-boosting Level ups



 * For every point that the player's magic level is boosted above their base level their max damage boost by 3%.
 * Wizard's mind bomb will boost your magic level by 2 if your base level is under 50 or by 3 for levels 50 and over.
 * Mature Wizard's mind bomb will boost your magic level by 3 if your base level is under 50 or by 4 for levels 50 and over.
 * Prayers such as Mystic Will and Augury only increase accuracy, not max hit.
 * None of the level boosting methods stack with each other, but the percentage bonus of the boosted magic level will stack with items' magic damage bonuses (e.g. that from the staff of light).
 * Damage boost is capped at 21%, but the level dependant base damage of Polypore staff and Storm of Armadyl are uncapped.

Special Circumstances

 * Charge is a spell which temporarily increases the maximum damage of the three God spells by 100 (providing the player is wearing the corresponding god cape). The spell requires a magic level of 80.
 * Salarin the Twisted (who is susceptible only to strike spells), can be hit 90 life points by wind strike, 100 by water strike, 110 by earth strike, and 120 by fire strike. These max hits cannot be boosted with items or potions.
 * Ice strykewyrms can be hit 1.5 times higher by players using fire spells, and 2 times higher plus an extra 40 damage (added after all multipliers, similar to a ferocious ring) by players wearing a Fire cape and casting fire spells (other spell types get an extra 40 damage with a fire cape, except ice spells which heal the strykewyrm).

N.B. the way in which some boosts are stacked has not yet been confirmed; your result may be slightly inaccurate. Please use the talk page if you have any evidence you'd like to contribute.

If you're using a Magic Blastbox or Celestial surgebox, increase your max hit by 25% and that'll be your actual max hit. But these only give additional damage every fifth hit

Maximum Magic Hit
Currently the highest magic hit in the game, known to be at least 1146, can be achieved by casting Fire surge on an Ice strykewyrm with the chaotic staff, Arcane stream necklace, Hexcrest, and Fire cape equipped, after drinking Extreme magic potion. The maximum total theoretical damage from one spell is 4,995, achieved by hitting nine targets with Miasmic Barrage for 555 life points each. A more probable instance in multi-way combat is to hit at least five (or more) players with Ice Barrage for 300 (or more with a castlewars brace and Arcane stream necklace) resulting in a staggering 1,500damage. <!-- These tables sholudn't be displayed, as:

-they aren't up to date -they are factually misleading as the % bonuses have been simply added, when this isn't in fact the correct calculation method -they take up a lot of space and unnecessarily bulk out the article -they are surplus to requirement to some extent given the fact a calculator now exists

Boosts are listed in the order they are believed to be applied. For instance, the +100 damage boost gained by the Charge spell used in conjunction with a staff of light would give a +115 bonus. However the order in which some boosts are stacked has yet to be confirmed.

Special circumstances, listed above, have been excluded from here.

The items listed below as Highest Applicable Boosts list the items that are not surpassed in terms of magic damage boost given, however some are tied. The Hexcrest is interchangeable with the Full slayer helmet, and Extreme magic potions are interchangeable with Overload potions.

Dungeoneering
It is worth noting that within Daemonheim, the magic potions increase in the same increments that melee potions do in both Gielinor in Daemonheim. That is, they increase magic far more in the former than the latter. Unlike in Gielinor, however, each boosted magic level in Daemonheim only gives an additional 1% damage bonus. Therefore, the calculator above only pertains to activities outside of Daemonheim, as this is a non-Daemonheim related article.

In the free game, with the Catalyic staff and Fire Blast requiring 59 Magic, the max hit is 184 because Fire Blast's max hit without any boosts is 160, plus the staff increases the damage by 15%. Some free players choose not to use the Catalyic staff due to the infinite fire runes offered through any other staff or wand.
