it most likely looks like a bug !!
becos, two SR rings stack .. giving u a good heal with meat, but am not sure its 100%, it shud be like 50% more of 50% !!
i dint have the need to buy Hell poodle, becos at 99 vit, it was healing me 900hp, almost equal to 1k, and my char HP was only about 12k !! 12 meats and u r good to go ..
i was thinking of upgrading to another HP .. wen u guys test it and confrim, do let us know in the forums, we can think of switching or using SR rings
but am pretty sure, u dont need two HP rings, unless u r like ridiculously High HP on WS and mobbing like a champ !
i think its also good in abyss for those dragons, since they almost get me one shotted
