To me s4 seems a little low, not very safe for magic duels. While on a lich you can somewhat count on immortality in friendly dom (but you can still lose your equip), the druid doesn't have this advantage. Nothing game-destroying for course (after the first one the wise druid will probably stay more on stealthy anyway)...
@Kissblade - I'm not a vet but I think you are a little underestimating the Gygja for the role Baalz has in mind. If I understood correctly the kitted ones are intended only to be teleporting thugs to squish the province defense cutting the retreat of the enemy armies which will run away with the morale shattered by fear auras, blood rains etc, thus condemning them to a rather pointless death
A 40HP 20str equipped Gygja seems to me perfectly capable of killing some PD
The Jotun Jarl can't teleport...
