Sleeper's Tomb Final Boss

Okay, found the way through to the magic ward thingy. Clicked it, notta.

Tried to find ANY type of info on this zone to clear it, and notta.

How do I summon the last boss to kill it? And what's the warder thingy for?

Nevermind, I figured it out. Had to mentor down to see the fragments.

Glad you worked it out. You can summon all 4 of the warders if you save up the fragments. The one that spawns is the LAST COLOR you pop in.

Also, if you choose the challenge mode, you won't be able to summon the warders themselves.
