Spell Damage

Note: These formulas are out of date.

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 T2	6
Holy T3	7.5
Dark T1	4.5
Dark T2	6
Dark T3	7.5
Explosion (note1)	0.73
Ripened Soul (note2)	0.2

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 50%

• (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.
