dose having your skills at 100+ actually do anything? or do you stop improving at 100
i have 100 blade and i'm thinking of using Oghma Infinium to boost it to 110

Generally, once beyond 100, there are no added bonuses to the skill, you still get the normal damage or whatever bonuses per point, but you don't gain any new abilities or anything. The bonuses you get actually seem to affect less and less after 100, based on how much higher you are. 150 blade is still better than 140 blade, but it isn't 50% better than at 100 skill, it's more like 20-30% better, if that. This is because most calculations are not based solely on the skill, but also equipped weapon, strength, the opponents armor, the opponents dexterity. Also, beyond 100 you won't raise the skill through usage.
