characters Health

My char is lvl 20 and its gotten heapz of skill points and stuff like that..but its health still stays at 480 I have seen some elementals with like 500-600 health

Is there somthink wrong with my character or is it the game?

nothing wrong with your character or the game, there are runes to increase health, along with weapons and off hands with health bonuses

a sup. vigor rune (+50) a hale upgrade (+30) and fortitude upgrade (+30) would be 590 health, throw in morale and that is 600+

Where can I get these runes?

You mean to tell me your health is 480 without runes? Maybe I'M doing something wrong.

480 is the base health at L20 with no modifiers.

There are several modifiers, such as vigor runes (as mentioned above), fortitude upgrades on weapons and some offhand items will also offer extra (or less) health.

Vigor Runes
Clean Weapon Mods
Fortitude Upgrades
Hale Staff Heads.

Those are all the ones I know of.
