After the tanky Ogre. please.

Oh and How does the Heightened Learning ability work with respect to INT/WIS gain?

And I believe poison is touch range spell correct? Hence it would be AGI/DEX vs AGI?

And it does 1D20% hp (from max or diminishingly?) per turn or per round? If per turn, on who's turn does the damage account for, I'm assuming the afflicted party's turn, at the beginning/end of their turn. Unless you mean per round after we all have one turn.
