Spellpower

Spellpower is a character stat crucial to all vocations on Medivia. A player's total spellpower is derived from their Level, their Magic Level and either their Intelligence (for mages and druids), Strength (for knights) or Dexterity (for archers).
Spellpower dictates the amount of damage your runes and spells deal (except for Berserk and Decimate), as well as the amount of health your runes and spells heal.
A character's total spellpower is calculated with one of the following formulas (rounded down):

Mages and Druids:

 magLevelMult = 0.85
 (level * 1.30) + (magLevel^1.4 * magLevelMult) + (intelligence * 1.0)

Archers:

 magLevelMult = 1.8 (3.96 with Arcane Marksmanship)
 (level * 1.30) + (magLevel^1.4 * magLevelMult) + (dexterity * 0.75)

Knights:

 magLevelMult = 6
 (level * 1.30) + (magLevel^1.4 * magLevelMult) + (strength * 1.2)
