Def reversal effects such as Ice Pick, Thanatos Card and Monk's Investigate skill have a custom formula.
- [Atk * ((100 - 10000 / (100 + (Enemy Armor * (Enemy Armor / 25 + 1)))) * (100 + Enemy VIT) / 100) / 100]
Examples (all using 100 for Atk): 1 Def/1 Vit: 1 Damage 50 Def/50 Vit: 90 Damage 100 Def/100 Vit: 166.7 Damage
