I have a rogue that i've been maxing Dex with, but i dont know what it does. Also a Guardian thats getting alot of vit.

What do all of them do, exactly?

Thanks much!

Strength:
- Increases physical damage (weapons)

Dexterity:
- Increases speed and chances to strike first during each combat round
- Increases chances of delivering a critical strike
- Increases damage done when a critical strike occurs

Intelligence:
- Adds to Max Magic at level up
- Increases offensive damage of spells (charms)
- Increases defensive vs. spells cast at you (hidden value, not shown)
- Items that give +Intelligence do not increase your Magic Points!

Vitality:
- Adds to Max Life at level up
- Increases defensive properties of armor
- Items that give +Vitality do not increase your Life Points!

Thank you very much my friend.

Am i right in my choice of stat allocations for my two characters? Or should i pump some into str on my rogue and more str on my guardian as well.

typically for melee characters 110-120 is a good amount to have (with gear)
and the rest can go into str

Ok, thanks for the tips.
