Good Tanker units?

[Muzzy]

I like shamens early on and to cast the totems. Most enemies go out the way to attack them first. Whilst you can cast spells and rage off from range. Phantoms a good spell to us with them and ice orb handy to tank with.

The problem is that either you have emeralds with stoneskin and target (assuming you have Higher Magic, otherwise just target - you'll have to use Sacrifice later on to heal them) or giants/ents with teleport - but then you have to choose between target and stoneskin.

A good tanker unit IMO is the Giant with Peacefullness. Else i suggest the Dwarf. Toooooo damn resistant!!
