The most recent deploy added damage resistance. Each damage type has a stat that boosts the damage amount, and on the receiving character’s end there is a stat that reduces the damage that will be taken. All damage is reduced with this change.
Here is an example:
Arcane damage is boosted by intelligence, ratio is 20 points. The counter is intelligence as well, ratio of 20 points.
Character A has 15 intelligence, Character B has 12 intelligence.
Character A uses magic missile on Character B, which does 10 arcane damage.
18 damage set at Character B.
12 damage taken by Character B.
Character B uses magic missile on Character A, which does 10 arcane damage.
16 damage sent at Character A.
9 damage taken by Character A.
