Lots of Hellfire Warlocks (WIP)

[Barbarian MD]

What about doing this:

1) slowing the progression after level 3

2) an option that allows you to take more con damage for more damage? Naberius only fixes 1 per round, so if you took 3 Con for a ton of damage, it'd cost you more.

That would create the same uber-powerful damage, but actually make it cost something. You could even prohibit the damage from being healed any faster than 1 per round.
