i went 50 base vita

but how good should my gear be before i well in hardcore...

and will there be mobs that 1 shot me o.o?

imo u just need the perfect heall charm,i play sc and mobs have hitted me @ 800 @ lvl 71 yet my heal charm heals me @ about 400-500 and i have alot of mana, so i constantly switch from each charm

Depends on level. I well all items lvl35 and lower at lvl 45 with a 105ee lvl 45 ice charm. I have a robe with 38 int, and a staff with 29int. I can do 95% of wells at this level. At level 55, i use a 123ee lvl 55 lightning, and can do around 85% of wells. By level 65, i can only do around 60% of them. But even being able to do 60 is enough to get lots of muteables. Having a heal charm against well bosses is almost useless unless you can get 150+ee.

The Key is the Heal Charm.

For high Level Wells.

Use 35+ Int Weapon/Armor or the highest you can get.

Use a 100+EE Charm and a 100+EE Heal helps a lot.

And Go at least 40 Vita and not under.
