The Harm Touch/Lay on Hands AAs should be fully functional at all ranks in Rev1790, in particular with respect to the required levels/cost to train them, and their associated spell effects.
HT seems overpowered
but I guess it is because it is designed for the current situation on Live.
For example, the level 65 HT does 10726 DD and 31857 DoT (4551 per tick for 7 ticks).
I think I have the formulas correct, from looking at SK/Paladin boards. If anyone sees anything wrong, let me know.
EDIT: The last two tiers of HT with a formula1 of 331 don't work.
