The High Aldwin
This reminds me of an idea from d20 SW and combining it with a system I was designing where there were three abilities and three saves.Physical: a combination of Strength, Dexterity, and Constitution.
Mental: a combination of Intelligence, Wisdom, and Charisma
Magical: a measure of one's affinity to magic, the supernatural, and the paranormal
Power: a measure of your character's ability to affect others in some way
Defense: a measure of your character's ability to resist others in some way
Luck: a measure of your character's good fortune.
But then you run into this...
we are playing a completely different RPG with vastly different dice mechanics. But that's what I think it would take to remove Intelligence (or any other ability score) from the game.
