Thinking about a Tamer class, bit like Lore master;
5lvl class.
Is blocked from summon spells like spellsword.
Free stuff:
Lvl 1 skill focus animal empathy
Lvl 2 bonus language animal
Lvl 3 summon pet. (Small animal companion)
Lvl 4 gain -track
Lvl 5 epic skill focus Animal empathy.
I don't know what sort of feats could be made to suit, I am thinking of stuff that makes a tramer "inspire" the animals they tame to get bonuses.
Tamer being able to tame certain animals normally untame-able, like spiders.
Animal lure. Untamed animals native to the area spawn near the tamer.
Stuff like that.
