Spell Damage

The spell damage formula is as follows:

Spell Damage = magic_base_damage * spell_damage_bonus * spell_modifier * (1 + hath_bonus) * (1 + tower_bonus) * (1 + crit_mod) * (1 + arcane_focus_mod) * (1 + channel_mod)

Factor	Description
magic_base_damage	Magic damage from all sources, including attributes, equipment and abilities.
spell_damage_bonus	Spell damage bonus of the spell's element. Commonly referred to as 'EDB', with spell_damage_bonus = (1 + EDB/100)
spell_modifier	Individual spells have individual modifiers (see table below)
hath_bonus	10-50% from the "Dæmon Duality" Hath Perk series
tower_bonus	0.1% per Tower floor cleared in the previous season of Isekai (Persistent only)
crit_mod	Critical damage bonus (if critical hit) - 50% base, plus equipment bonuses
arcane_focus_mod	25% bonus if Arcane Focus is active
channel_mod	50% bonus if Channeling is active

Note 1: Damage range for Explosions is 0.5-1.5 instead of 0.8-1.2, and they cannot crit.

Note 2: These procs do the same damage no matter the target, ignoring specific and magical resistances.

After the Spell Damage has been reduced by the monster's mitigations, it is finally rolled in a range of 80%-120% with steps of 1%.
