This level, I'm thinking about getting rid of my wings and giving myself a +8 Diplomacy and a +8 Ride and giving my eidolon the mount evolution so I still somewhat have the mobility that I'm used to. The issue is that I'm human and therefore my eidolon has to be large. I don't mind that, but I like being prepared for every contingency. So what I'm wondering is if there is a way to make my eidolon medium sized in case we have to fight in a 5 ft hallway?
I could make my eidolon medium size and use Evolution Surge whenever I want to ride him but with a mount setup that seemed a counter-intuitive way to go about it, since the spell only lasts for 1 minute/level. There should be a way to temporarily reduce his size for 1 minute/level instead of increasing it. Any ideas that aren't super expensive?
Transmogrify is a bit expensive and can't really be done on the run, otherwise, I'd just use that.
Summoners have both 'enlarge person' and 'reduce person' on their spell lists, and can share-spells with their Eidolon.
That's a 1min/lvl solution, for a 1st level spell slot (or scroll).
How many 5' wide corridors do you encounter at lvl 8+?
Not too many, I'll give you that, but we do find them. We're playing through the Jade Regent AP and two sessions ago found a secret entrance into a castle that was a 5 ft oval-shaped hallway and only about 5.5 ft tall. Taking my eidolon through that would have been hell if he were large.
On the other hand, a wand of reduce person should completely fill that gap, since it will probably only be a one level deviation (I really like my wings). Thanks for the idea, badgerish!
