controlled chaos

a blast of pure chaos from limbo itself, roll 1d4, this is your multiplier, then, roll 1d8, if you rolled a 1 on the 1d4, this is your damage, if your 1d4 rolled a 2, 3, or 4, then the 1d8 is how many dice you roll next, repeat this process until you hit the number of rerolls as the d4 told you
