He has +2 str, resistance to poison and immunity to diseases as well

Meanwhile he is immune to any damage IF it would be from ingesting it (as in if he eats a zombie, golem, or fire elemental, he would take 0 damage from the meals with other people if it's from a meal he himself made taking half the damage, meanwhile he expertise in con saves, then resistance to anything that can be deflected with his fat (bludgeoning being innate and the only one for westmarches, but rest is up to DM if in a campaign).
