con and barb rage

[MondoGrunday]

i know con and barb rage are related, eg. duration etc. but does your rage increase with a con increase from items and enhancements? or is it only from base stat and enherent (tomes)?
thanks in advance

Barbarian rage increases in duration as you obtain CON from any source.

Rage duration = (3 + total, modified CON score modifier) * 6 seconds. So, Rage from spell, Madstone Rage, Bloodstone Rage, CON items, all add to Rage duration. Make sure you use these clickies/potions before you Rage. :)
