W/Mo tank

Could I get help on how to kill them when i am last man standing and have used my res signet and am getting whacked upside the head by 3 wariors and a caster.(also I know i am lvl 15 I use this in the arena by yaksand the way it is if the warriors keep hitting i can tank forever)

Ok i hate Photobucket.
But thats:
healing:8
smiting:5
Strength:7(helm and minor)
Swordmanship:9(major rune)

My sheild is health+36 while enchanted.
Sword is max dmg req 9 dmg+15%>50%(made at droks) with a pomel+29 and a surendering sword hilt armor penatration 10%(chance 10%)
Skills:Savage Slash/ Sever Artery/ Gash/ I Will Avenge You(for regen mostly)/ Helaing Breeze/ Balthazar's Spirit(to maintain energy and dmg)/ Mending/ Res Signet

15k armor... drok weaponry... griefer build at yak's arena...

for shame!
