So I have a unique trap house which I use Rainer for trapping (as most should) but I came up with an idea of a new shaman. Eir the Healer will specialize in Infirmary Troop Increase, Infirmary Healing Time Decrease, Infirmary Cost Decrease and Valkyrie timers/cost decrease. As for it's Skills:  Infirmary Troop Increase, Infirmary Healing Time Decrease, Infirmary Cost Decrease, extra ghost bonuses and Valkyrie timers and cost

Eir the Healer's lore is about healing and protecting which in some tales considers her a Valkyrie. Based upon that she would most definitely fit the theme also all account (especially those who messed up their Valkyries would benefit from it). The only reason I added in the Extra Ghost Benefits is because every shaman has the exact benefits across the board but this can easily be removed.
