So I'm playing a Summoner synthesist in a world where magic is outlawed. This means if he's seen in his eidolon suit it's basically a death sentence.
To get around this, I was going to get him to use the disguise skill to look like 'himself' even when fused with his eidolon. Looking online I see there's some debate about whether you can take 10 or take 20 with disguise, but for the sake of argument let's say I could take 10 hours or so to take 20.
In this situation, how long would this disguise last? would I never need to roll another disguise check again to look like 'myself'? Or would I have to do it every time my eidolon was summoned, or every x hours or what?
Also, I'm sure I read somewhere that you get a bonus to disguise if the target wears a distinctive outfit or uniform, but I can't remember where I read it. Anyone know what that's from?
