Spell Damage

These formulas are slightly out of date.

The spell damage formula is as follows:

damage = max(1, (damage_range * spell_data * magic_dmg * critmod * 
aoe_mod * channel_mod) * defense_mit)

Factor	Description	Formula
damage_range	The variable range of the spell's damage	0.72-1.28 on average
spell_data	Damage factor from the spell	(See below)
crit_mod	Bonus for critical hits	1.5x (1x otherwise)
aoe_mod	Bonus for the primary target of an AoE	2x (1x otherwise)
channel_mod	Bonus if Channeling is active	1.5x (1x otherwise)
defense_mit	Mitigation for the element and attack type in question	Varies

Spell	spell_data
Magic Missile	1.2185
Elemental T1	1.3
Elemental T1 AoE	1.04
Elemental T2	2.08
Elemental T2 AoE	1.56
Elemental T3	2.6
Elemental T3 AoE	2.08
Soul T2.5	2.08
Soul T2.5 AoE	1.56
Soul T3.5	3.12
Soul T3.5 AoE	2.6

Dark T4 AoE	2.6
Holy T2	2.08
Holy T2 AoE	1.56
Holy T3	2.6
Holy T3 AoE	2.08

magic_dmg is calculated separately as:

magic_dmg = (base_bonus) * (1 + elem_bonus) * (1 + prof_bonus)
* (1 + boost_bonus) * (1 + hath_bonus) * stamina_damage_factor

Factor	Description	Formula
base_bonus	Magic attack base damage	MAD / 100
elem_bonus	Element spell damage bonus	EDB? / 100
prof_bonus	Magic proficiency	Prof / 200
boost_bonus	For every Ability Points put into an AoE spell past the first	+6.25%

stamina_damage_factor	The bonus from stamina being over 79.	+25%
