Tree of life

has anyone built a tree of life or whatever it is called for the other races?

is it worth it?

I haven't, it supposedly makes the heroes of that building's race better in some respect.

I know I've seen some pretty wicked spells in the Arena that I know didn't come from the regular magic tower.

They help heroes of the appropriate type while commanding units of the appropriate type.

So an elf hero leading elf units can get ranged and speed bonses for the elf unit.

Makes my main Orc hero kinda shitty. I'm devoting a lot of effort into upgrading my tavern to get a good elf hero to use these passive spell effects.
