Hey there,
i have always been the jerk who likees to k/m as mdps, tho i suggest something that way:
Let "Light Energy Weapon" (ID:490034) increase the light damage based on how much Intelligence you have.
To have an example, maybe for each 2000 points Intelligence 1% more light damage.
Friendly regards Nethrandiel.
Addendum: And yes, i am serious about that^^
