Here is the updated version of the Wisdom table from the Player's Handbook, as the table had too many listed 5th level spells as bonus spells. Thus with this new edited version, it is more streamlined and with the right proportions of bonus spells in the end, for a being with a Wisdom score of 25.

Demi-Human Experience: All demi-humans that are half-human must only earn double the normal experience as a full elf or orc, as their human-like mind also seeks things as quickly as their human parent, but the non-human part still holds them back, but only slightly compared to a full blooded non-human!

Priestly Healing: Since clerics and other priests get the shaft in the way of spells we have implemented healing rules very different than those of the Core Rules type books for AD&D. The changes are below and the main difference now is that priests get bonus healing points equal to half their level (rounded up).
