Another note:
With a geddon helm build, you have a few skill points to spare past level 94. Here are a good few ways to use them up:
Pump Heart of Wolverine:
Boots your bear damage a little bit. Not a huge change though
1 Spirit of Barbs:
Can be used a little against some melee like BvC. Not a bad idea at all. Definitely worth a point, once you can spare it.
1 Werebear/Shockwave/Lycanthropy:
This uses up a big chunk of your skill points. 5 points means you'd need to hit level 99.
If anything, you could actually skip lycanthropy entirely. But if you get these, you can either use it for messing around, and possibly against some high FCR sorcs with some trickery
but do not get me wrong: this is not worth getting at the expense of your skill synergies. you will never ever need wereform, its just a messing around thing, like a delirium helm.
1 cyclone armor
I'd strongly advise this tbh. You use it enough that its worth it. Without the geddon route, you don't get it. Comes in dead handy against auradins/trappers, and I still use it against some fireballers/etc to take 1 more hit overall
1 poison creeper
It doesn't really do anything, but it doesn't hurt to have.
1 carrion vine
Useless or BM in pvp, but seriously great in pvm.
My build would look something like this:
20 firestorm
20 boulder
20 fissure
20 volcano
20 grizzly
3 heart of wolverine
1 cyclone armor
1 spirit of barbs
