The spell damage formula is as follows:

Spell Damage = max(1, (damage_range * spell_data * magic_dmg * critmod * channel_mod) * defense_mit)
Factor Description Formula
damage_range The variable range of the spell's damage 0.8-1.2 on average
spell_data Damage factor from the spell (See below)
crit_mod Bonus for critical hits 1+(0.5)+Crit_Mods (1x otherwise; 0.15 from Better Arcane Focus, specific gear and potencies can give additional mods)
channel_mod Bonus if Channeling is active 1.5x (1x otherwise)
defense_mit Mitigation for the element and attack type in question Varies
Spell Base 1 AP 2 AP 3 AP 4 AP 5 AP
Elemental T1 4 4.1 4.15 4.2 4.23 4.25
Elemental T2 5.5 5.63 5.71 5.78 5.82 5.85
Elemental T3 7 7.15 7.25 7.35 7.42 7.5
Holy T1 4.5

Holy T3 7.5
Dark T1 4.5
Dark T2 6
Dark T3 7.5
Explosion (note1) 0.73

magic_dmg is calculated separately as:

magic_dmg = (base_bonus) * (1 + elem_bonus) * (1 + hath_bonus)
Factor Description Formula
base_bonus Magic attack base damage MDB
elem_bonus Element damage bonus EDB / 100
hath_bonus The "Dæmon Duality" group of Hath Perks +10 to 30%
  • (Note 1) Damage range for Explosions is 0.5-1.5 instead of 0.8-1.2, and they can not crit
  • (Note 2) These procs do the same damage no matter the target, ignoring specific and magical resistances.
