Ment
Auto-translated
Ent is a living tree, mega-ent is a huge living tree.
Conclusion - it's the same thing and cannot be creatures with different stats (i.e., 6. Ent, 7. Mega-ent).
A phoenix would be a good choice for level 7, since there won't be any dragons. Something similar to Heroes 5, with resurrection and high initiative, but not very high health.
