A Pain Psychic gets Live On, which is Lay on Hands at your psychic level -3. It explicitly stacks with lay on hands abilities gained from other sources.
A VMC Paladin gains the ability to lay on hands a number of times per day equal to 1/2 her character level, healing as much as a paladin of her character level – 4.
Since they explicitly stack, does that mean you add them together into one big pool of lay on hands? Would a level 20 pain psychic with VMC paladin have 18+cha uses of lay on hands that heal 16d6?
Bumping to see if anyone knows.
they more likely either stack in the amount of LoH you get OR the lvl equivalent you get it at
