The Vine Ogre

Usually you do not get one Vine Ogre per casting, but two: the Ivy Crown replica gives you one more Vine Ogre per summoning, and you should have one of those items per Vine Ogre summoner if you are serious about it. Vine Ogres seem cheap enough at 0.5 gem the unit, if you have enough mages to summon quite a few of them.

I should have been more clear. IF they cost 2 gems per casting then they would still cost 1 gem for nature summoning during the early game.

So, maybe an Ivy King should cost 30 gems. I think they'd still be worth it.
