Epic hide and invisibility

[herculesftw]

Invisibility gives you +40 to hide if you're not moving and +20 if you do move. Could you by RAW minus 30 to your hide to give someone else not moving +10 to hide, or if you had hide already, even higher?

[TuggyNE]

Assuming they meet the requirements (cover or concealment), you can hide them. There isn't any particular way to give +10 to another's Hide check, though; you either succeed, fail, or successfully Aid Another for +2 on their attempt.

There is no specific restriction on who can attempt epic skill DCs.

[Pickford]

The DM limits cooperation as he or she sees fit for the given conditions.

My opinion would be that you could help someone hide by standing in front of them (i.e. being the cover) or by distracting the person they're trying to hide from (Of course, this is actually covered by several skills/tricks/feats).

But otherwise, no.
