Highest regen possible?

[DLC1]

i had 147 regen/turn with my earthmother wearing hydra armor, ring of regen and crown of vine men(one that gives regen) and 10 in dominion.

whats the max on eater of the dead? and has anyone tried great wyrm with c'tis and crown of vinemen + that c'tis only helm with +regen and ring of regen?

the water elemental queens have the highest natural regen ofcourse but they have low hp, i'm more interested in the earth elementals or father illearth equipped with the regen equip.
posedeion would be kinda hard to beat with regen items + invulnerability and lucky coin & bloodthorn.
