ToME: the Tales of Maj'Eyal

Ok I thought I understood until I got this rare:
Damage conversion: 37% mind/ 38% ice/ 45% acid blind (120%)
So if I'd normally do 100 physical damage am I now doing 120 total? or is this an anomaly from random-arts & it shouldn't go over 100%

The damage conversion works in a loop, i.e. the first conversion is applied, then the second on the remaining damage, then the third on the remaining damage, and so on.

If the order is 37% mind/ 38% ice/ 45% acid blind, then you will do instead of 100 physical damage:
100*37/100 = 37 mind damage
63*38/100 ? 24 ice damage
39*45/100 ? 17.5 acid blind damage
and around 21.5 physical damage.

thanks! Makes more sense now.
