One of the major things we’ve decided to do with our Five Color Game is to remove the ability score for Wisdom from the game. This wasn’t a light decision, and I’ve always been a bit of a fan of WIS for a number of things. But with the removal of clerics and druids and the simplification of many other things, we’ve decided it had to go. The characteristics that WIS encompasses have mostly been included in INT.
We considered using both INT and WIS as key components of our wizard classes, such as using one to determine success rates and chances of learning spells and the other to determine bonus spells. But that made the wizard class too dependent on two ability scores, and we’re trying to do a bit to untie the playability of a character from the scores rolled up during creation. So we rolled it all into INT. Wizards must have an intelligence score of 11 or more. Others must be warriors, which have no minimum requirements.
This leaves us with 3d6 in order for five ability scores, each of which can be modified based upon the color the player chooses for the PC.
This will likely be heresy for a great many.
