In Ob whether you had 1% 80% you always looked see through but you could tell you were there. I hope in Skyrim that you'll only look mildly see-through with low chameleon percentage.

I wanna be invisiblez..

In oblivion you did become more invisible the more you had chameleon, it's just that the 3% base value already made you so invisible it's a barely noticeable difference. Morrowind had a more actual chameleon feel to it, I hope they use that as a base.

That makes a lot of sense. In OB, chameleon affected detection range, not chance, so it did seem a bit odd that you were totally see through at 10%.

From what I recall, a chameleon blends in with it surroundings, it doesn't go invisible, same concept in OB and probably Skyrim
