Magic Damage

Various items in RuneScape allow spellcasters to increase the potential maximum lifepoints damage. The effect of worn items can be seen in the stats window in the Magic Damage Bonus percent, whereas boosts gained by postion-boosted levels can be calculated manually and added to the equipment bonus.

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


 * The Hexcrest and Full slayer helmet's 15% damage boost only apply when casting spells against a currently assigned slayer monster.


 * For every point that the player's magic level is boosted above their base level increases their damage boost by 3%. For instance, if a player with 90 magic drank an extreme magic potion, they would have 97/90 magic, which would add 21% damage to all combat spells the player casts.

Maximum hits
Currently, the highest percentage boost possible is 66%. Could someone with programming knowledge make a table with the base spell maxes (there's one in the magic article) and then apply the 66% to it and show each max?
