10 Most Powerful Summons In RPG History

1. Karstaag - The Elder Scrolls V: Skyrim

A summon so powerful, even a game as open as Skyrim only lets you use him three times and makes it a pain in the ass to get him in the first place, we have Karstaag.

After my big speech about how we’re not allowing Dead Thralls, we are bending the rules a touch for Karstaag as you summon him with a power and not a spell, but I’m going to allow it. This guy was infamous on r/skyrim for being nigh-on unkillable. He’s a hugely powerful frost giant you’ll need to defeat if you want to be granted the opportunity to call upon him in battle.

And, like I said, you can only do that three times total and then Karstaag is over being the Dragonborn’s whipping troll… ghost.

He’s level 90, does a wild amount of damage, and has a stomp attack that’ll ragdoll your hero right across the room. Not to mention his frost cloak that inflicts frost damage, multiple immunities, and ability to summon Ice Wraiths on the side.

If you manage to take him out, Karstaag is going to end just about anything you point him at. For comparison’s sake, this guy is going to flatten your Dremora Lords as quickly as you can summon them.
