1) Super strong early expansion
2) Very strong research- hammers + skulls + quills
3) Very strong combat magic
4) Strong death mages for powerful summonings.
5) Unmatched hit and run capabilities
6) Assuming a F/W bless they've got a strong mage in 5/8 of the magic paths
7) Even a taste of blood magic if you're feeling frisky

Yep, sounds like the recipe for a weak end game to me.

The only thing worse than early game Helhiem is late game Helhiem.
