[@13org]Right here we go! This is all up for discussion so let me know what you think :D

Úlfheðinn's Might: Nanna enters a bloodlust state, toughening her body for battle.

Spearmaiden's Lunge: Either she moves superbly fast, or her spear is more likely to hit. If it doesn't, the cost is refunded.

Walküre's Bloodlust: She may inspire fear in a person during battle.

Bump Yggdrasil's Blessing up to slot 3 and move Yggdrasil's Roots to slot 1.

Yggdrasil's Blessing: She can cure minor/moderate wounds to one person, with more serious injuries requiring more lifeforce to fully heal. If the wound is fully healed, the character feels invigorated for a while.

Yggdrasil's Dew: Can you be more specific about how you imagine this ability works? Many other characters have a spirit summoning ability at their strongest ability level, so perhaps this can be a distract, illusion or ensnare type ability :3

Yggdrasil's Roots: happy with this, good job :D

Contract with Yggdrasil: Ignoring all magical effects is pretty OP, so how about a shield that can absorb magic attacks? It wouldn't be permanent, though :P
