Resist
From BGWiki
Resists lower magic damage negatively. A spell can be resisted only in these increments:
1/1 (No resist) 1/2 1/4 1/8 1/16 (Full resist)
An exact formula for resistance is unknown, but for elemental resists there are tiers which affect how often one resists that element. For example 320 resist is the known cap. When fighting Tiamat, with 320 fire resist Tiamat's magic damage will be fully resisted ~95% of the time.
