Oak Sage / Heart Of Wolverine: 20
Grizzly:20
Rabies:20
that's about 65 skills points so lots to play around with... If you can get a carrion wind for the poison creeper synergy bug...The remaining skills can be used to put points in dire wolves for stronger summons (probably not the way to go)...getting a backup elemental skill (maybe fissure..)...get cyclone armor for added protection. Oak Sage or Heart of wolverine is a difficult choice... I'd go with Oak because I like massive life (who doesn't) but HOW could be very useful to add to your minions damage and enable you to hit better with your rabies. Alternatively you could also make a hunter... a druid with a bow+summons, that would also free up some more skills to get really good damage out of an elemental skill. As for gear... pretty much standard caster gear.. Heart Of The Oak flail, Chains Of Honour/Enigma, Shako, Arachnid Mesh.. etc... then on switch maybe a long range and fast weapon to safely deliver rabies from behind your summons...
You should also definitely get a might mercenary as he will boost the damage of your summons and himself... some of the runewords that grants auras would also be very sweet... Beast & Pride would be very excellent.
