Spell Damage

The spell damage formula is as follows:

Spell Damage = magic_base_damage * spell_damage_bonus * damage_range * 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)
damage_range	Random roll between 0.8 and 1.2
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
