Should I even be surprised that Rerir has an abyss form? The entire point of the sinners is that they stole abyss powers, lol. In fact, he might be one of the weakest sinners since he gets consumed by it.
In terms of strength/brokenness:
1. Surtalogi (looks like a 10 years old kid wrote his lore, lol)
2. Gold (became an actual god)
3. Dains' bro (can see the future and even different timelines)
4. Do we even know anything about Hroptatyr?
5. Rerir (bottom of the barrel, the Tartaglia of the sinners)
