These two spells, the snow and lightning, must certainly be third level, each consuming at least 15 mana points.
Adding the entanglement technique from before, the spell that left her hanging upside down in the tree, and her abnormally fast speed which must all be the effect of spells, the latter at least being second level, that's 25 mana points already.
Plus the Druids' commonly used Tree Skin Skill, and the arrow-shaped spell, even if they are just first level, each would require 5 mana points.
A rough estimate shows she has already used 115 mana points.
Her mana value is indeed terrifyingly high, her Perception Attribute must be over 15 points, but she must be nearly out of mana by now.
As for him, up to now he has only used two Fireball Techniques and two Shield Skills, merely 40 mana points, and his guards have absorbed most of the damage from the lightning strikes.
