Magic Damage



Various items in RuneScape allow spell casters to increase their potential maximum magic damage. The effects of equipped items can be seen at the bottom of the stats window (labelled Magic Damage: +x%). Temporarily increasing your magic level also increases your max hit (by 3% per level boosted).

As far is known, all of these bonuses stack, as long as they can be worn/ used simultaneously.

Damage-boosting Equipment

 * The Hexcrest and Full slayer helmet's 15% damage boost only apply when casting spells against a currently assigned slayer monster.
 * The Ferocious ring boost all spells' max hit by 40 when fighting monsters in Kuradal's dungeon. The bonus is applied after applying the bonus of the 15% slayer helm bonus.
 * Chaos gauntlets boost all bolt spells' max hit by 30.
 * 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.
 * A full set of void knight armour won't raise your max hit just 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 of by 3 for levels 50 and over.
 * Prayers such as Mystic Will and Augury only increase accuracy, not max hit.

Max Hits
Currently, the highest percentage boost possible is 66%.


 * The Charge spell temporarily increases the maximum damage of the three god spells by 100 (providing the player is wearing the corresponding god cape).
