"School of Piranha" doing level 1 dmg at level 3

[Fatt_Shade]

What mod you play ?
Did you try to play same battle couple of times and cast this spell to check dmg results. And did you check enemy resistances, shoal of piranha is physical dmg spell so this res makes great difference. If you play some mod with unit having experiance lvl`s they get higher resistances,and get reduced dmg from spells/attacks.
