Really weak unit spawn on hard

[loreangelicus]

Well, if you use your pet dragon to dig a lot, then chances are you could get wanderer scrolls to get you a FULL stack (depending on current leadership) of the following:

Call of Death: any undead unit, notably bone dragons/black knights/necromancers
Call Colossus: any level 5 unit
Call of the Wind: an assortment of unit types, royal griffins and dryads being the best

I'd say that Hayterrants are one of the best units to come out of the Song of the Wind scroll Tough, spawn more hayterrants and the eggs can even survive a few hits before hatching.

Hayterrants are exactly half the leadership value of Royal Griffons. Numbers-wise 1 RG beats 2 Hayterrants.

Maybe if the stack is big enough the Hayterrants from the 1st egg can lay a 2nd egg that will spawn a useable amount of Hayterrants which can lay a 3rd egg and so on...

[Zechnophobe]

Yeah, for a level 4 heyterrants do really bad damage. And summoning angelic griffons seems to be better than... more heyterrants.
