support Barb/Blade... your job isn't to tank.... it's to add dps to the fight and to WATCH FOR ADDS and take them on, especially if they are going after the casters (i.e. your cleric).

Don't focus your view on the boss.. click your attack and then start rotating your view to keep all the other mobs (if any) in your view.

Tanks.... Your job is simple.. Piss the mob off. use all your agro gaining/Hate gaining attacks to get rose zuly, constantly. If you need spark and a veno is around.. hopefully they will have the skill to share a spark with you ( Lending Hand ). don't hesitate to ask for a spark if they do. Keep the mob pissed at you. Spam your agro attacks constantly. Also.. keep an eye out for adds.. If your the only tank.. your gonna have to grab them while the others switch off to kill them. If you can keep agro on adds for a few seconds, that is often enough for the casters and support dps to grab them and take them out.

Finally... Venos.... If your the tank.. heal your pet, watch for adds same as a "normal-traditional" tank... if your NOT the tank watch your pets damage.. if it starts to out tick the tanks damage, pull your pet back for a few seconds. Watch your casting as well. If you have foxform skills like amplify damage etc (your curses) USE THEM. If not then use Ironwood Scarab to debuff the mob.

I commonly go to foxform and hit the mob with Amplify damage, then after it's almost ticked off I use Soul Degeneration, switch to normal form and hit with ironwood Scarab.. tick off till foxform is available again and go back to foxform and wait for Soul degeneration to tick off, then hit with Amplify again and rinse and repeat.

For non AOE bosses this works real well. For AOE bosses not so well.. i'll skip foxform and just use ironwood Scarab and maybe a DoT attack every now and then like Parasitic Nova etc... Again.. keep a VERY close eye on your damage.

*edit* Tanks that have a hp recovery skill. Save this skill. If a party member gets killed (hopefully not the cleric) inform the cleric your skill is avialable for use so they can stop healing you long enough to rez the party member that has died (if there is only one cleric in your party, if there are two, the support cleric should rez and allow the primary cleric to continue healing the tank.).. Also tanks.. you have HP charms available, Potions, Powders etc... you should be using these as well to help save the clerics mana.
