Did I over do it? Now it says enchanting potions are 1% more powerful.
The potion power number overflows and goes to a lower number. I made a 5838% potion once and the effect went down to 407%. So the overflow point is around there, I think. Highest potion I made that worked was 2473%
Once I made an Elven bow that does 994 damage. Its value was 14178. I made it while wearing 4 pieces of 830% Smithing Enchanted items.

7 if you count the notched pickaxe 
I said that the number is soOOooo massive that it's just as well to say there is no weapon damage cap 
Dragons are still a bit of a pain but strategy and use of the surroundings help
