Baldur's Gate : The Sword Coast Chronicles : NWN2 Persistent World

More questions:
1) -The base Barbarian Rage has been increased 5 rounds. Does this 5 rounds get added to the bear form or the whirlwind Frenzy for that matter?
My bear warrior has whirlwind frenzy...and of also bear shape. Should I have taken the standard rage to get that 5 extra rounds - especially for bear form?

2) -So I heard that the barbarians weapons AB and Damage bonus transfers over to the Bearforms attacks. Is this true? Is it only true with goves? Or do weapons matter at all in bear form?

Looks like a fun class, if I can get the rages to last long enough. I think the bear shape should be bigger, but I just made my character small, so they scale better .

1. yes, it doesn't matter which rage you take for bear.
2. yes, any weapon.

What exactly is it that causes the massive HP loss when you go back to human shape? I'm not sure what to do when I'm lowish on HP and I know my duration is about to run out. I'm using a helmet with CON bonuses right now, should I get my CON bonus from a different item slot?

I just died at Chaos after defeating everything, well there was one of the flaming skulls left, but I had 100 hp left and died when my rage ran out

Edit: I just noticed while in the fugue plane that all my gear bonuses were gone, so I had to re-equip everything.
