Anything that's size 4 is enough to stop them. You can't build anything that big, though.

Troglodytes don't have good protection, so you could try archers. Just recruit lots of indy archers and have them shoot at the Troglodytes. They have lots of hp, but they'll go down quite fast. Blade Wind would also work.

Troglodytes' magic resistance is respectable 12, but you could still try False Fetters. Earth Meld can also be used to ground them for one turn, but unfortunately Troglodytes are strong enough to break out from that in one turn.

Be sure to fight in cold lands. It won't help against the troglodytes, but Agarthans are cold-blooded. They'll get tired very fast.


EDIT: Fixed a typo in the first sentence. Size 4 is enough. Size 5 also works, but size 4 is enough.
