Okay, here's the thing. My DM allowed me to take feats for which my Binder qualifies when bound to a vestige that'd allow him to qualify for them (like Divine Feats if I have Tenebrous bound, or anything with Combat Reflexes with Paimon bound), but I'd only benefit from them as long as the vestige was bound to me.
Currently, my character is a Binder 6/KoSS3, with Improved Binding (which means so far I have access to level 5 vestiges and can bind two at once).
So, here are my queries:
1) Which feats are looking good for given Vestiges? (Divine Might for Tenebrous, or SUS for Ronove, etc.)
2) Which vestiges are SO DAMN GOOD I'll want to keep them close by forever so I can fully benefit from the feats?
Oh, and for the record: patron vestige is Andras, Str 14, Dex 14, Con 14, Int 13, Wis 10, Cha 18.
Current feats (We've got one for every even level, character is human):
Improved Binding, Expel Vestige, Weapon Focus (Lance), Battle Jump, Knowledge Devotion, Skill training: Athletics (yup, we're using a Saga-derived skill system too).
