Scarlett or 2nd Gormek

[Gryphonknight]

Roster

Depends on your roster.

Scarlett

I tend towards diversity first, then duplicates, but your play style may be different.

So with no information, another red 4* before a second Gormek.

Colen may be the only exception among red Classic 4* heroes, but Colen is another rant.
