[Celjabba]

Usually, an universal ability is *5 (sometimes *10) the cost of a focused ability, depending of how many variant there are.

Given the cost of magery and the relatively low number of variants , taking each variant as AA is cheaper, assuming you are ok with only one of them being active at the time.

So, cosmic +100%(equal to up to 5 alternate) would be a fair price assuming you can only use one at a time.

If you mix several otherwise incompatible power sources, like magic and divine in some settings , cosmic +300% may be in order.

Absolutely universal magery, giving bonus no matter what or where, would be *5 cost but likely too expensive in most settings. Although it would probably be fair if it included RPM, Incantation and others.
