figuring out feats and build for an animus ranger past lvl ten?

[aithe4ngel]

So my group consists of a half ice giant sorcerer with leadership who uses words of power,his cohort garnash a gnoll rogue,and his flesh golem patches, and a oread druid with a focus on a tanky wolf mostly working on evolution's and happens to be the queen of the forest at the moment.

I am a animus ranged ranger with +2 mithril breastplate on me and my hippogriff rhapean. I am a sky stalker and mostly only use the spell gravity bow and lead blades on my ice giant friend. I am trying to figure out what to get next for my character so I can keep up with the ice giants aoe's and the druids massive melee wolf.

I have a +4 c. longbow and need help picking enchantments.Also I was thinking of getting monstrous cohort.What would be the most effective monster to get?I have gotten snap shot and have worked my way up to rapid shot i'm thinking many shot and stand still are there other feats i should look at?

I hate to mention it, but gravity bow and lead blades each affect only the caster['s weapons]; you can't use either on your friend.

Unless this 'animus' thing gives you special abilities to do so? I'm not familiar with it. 3rd party?
