So anyone who has played magic may know of a card called the Steamflogger Boss. It uses a mechanic that is useless and has been confirmed as a joke by wizards. I want to play him in Pathfinder. There is only one real problem, and that is that goblins get a minus to charisma. Luckily the only thing really effected by a low charisma is bonus spells and times per day on my special summon monster. Both of these things I am willing to sacrifice for fluff.
For an idea of what the eidolon looks like take a peak at Gatherer for Steamflogger Boss. The actual card shows a biped mount but pathfinder does not allow this so quadruped it is.
My characters basic story is that he was a Goblin Welder (also magic card) and while tinkering with an old children toy(action figure in form of eidolon) he unlocked the eidolon from it's imprisonment and was granted summoners powers and spells as a result.
My character is a wise ass trickster (he's a goblin remember) so traits that help him do that are nice. I was also wondering how legit it would be to exchange the simple weapon proficiency for a single exotic weapon proficiency. I really want it to be able to use a whip. If fact when hes at his best I want him making a trip with bite, two grapples with pincers and a trip with a whip. I was also wondering if augment summoning works on the eidolon, the wording is a bit funky since he is treated a a summoner monster but a summon spell was not necessarily cast.
What I'd like from everyone is thoughts on the concept, and some ideas for feats or traits that can improve my character. I'm not sure what level he will be so suggestions for all levels are welcome.
