Notes
When cast as a Druid spell by a caster with at least 30 base Dexterity and whose base Dexterity is higher than their base Wisdom, casts Storm Avatar instead. Storm Avatar grants all the bonuses of Divine Power, plus the physical damage bonus of the Stormlord version of Magic Fang. If the Druid has the Extend Spell feat the duration will automatically be doubled, note that for this case the base duration is changed to that of Divine Power and not a flat 10 rounds.
