Cosmic: Always rolls a 10 (+xx%)

[Say, it isn't that bad!]

*As Ghostdancer previously suggested, Take 11 is probably more appropriate (leaning on the "bad" side of average, much as d20's Take 10 rule does), with +5% per -1 to the result. Actually, it should probably be an increasing price as you go, as otherwise you could technically make it Take 3 +85%, which is obviously far too cheap for that. Maybe something like the following.

Roll	Price
16	+20%
15	+30%
14	+40%
13	+45%
12	+47.5%
11	+50%
10	+55%
9	+65%
8	+80%
7	+100%
6	+125%
5	+160%
4	+200%

Note I left off rolls of 3, simply because any time you have an effective skill of 3 or higher (that is, are allowed a roll), a roll of 4 is sufficient for a Critical Success. This is a rough draft - +300% may be more appropriate for rolls of 4, for example ("Always Critically Succeeds" is a pretty big deal).

**This is probably worth less as a Limitation the lower the roll, and more as a Limitation the higher the roll, but I'm not sure what rate it should change. Certainly, it's +0% for a roll of 4, and probably -40% for a roll of 14 (for a net +0% there), but I don't know beyond that.

For "Take X Only", perhaps move 2 or 3 rows up the chart? So "Take 4 Only" might be worth +100%, "Take 11 Only" might be +40%, and "Take 14 Only" would be inaccessible.
