The Hidden Forest

I'm currently working my way through Kael and Shadow haven and finding that my wizard draws agro very quickly. The rogue and mage (With T8 pet) start attacking and nuking when the boss is at 90%. The wizard starts casting at 80% and waits 10 seconds between casts. Somehow the wizard still draws agro.

I'm going to get the reduce agro (necklace or belt or whatever it is) from Shadow haven. I know there is also Concussive Strike Rk. I.

I'm tanking with a warrior.
Is there something else I can do?

Thanks for any advice.

There are a few items and augs you can use to create extra hate on your warrior such as :

Don't just "wait" for 10 seconds in between casts. Your wizard should already have Ancient: Greater Concussion just by talking to the spell mushroom guy in forest which you can spam for 10 seconds in between nukes, but this spell (a crappier version of concussive strike rk. I) may prove that you only need to cast it once or twice before nuking again (less than 10 seconds) and not draw agro. you'll have to play with it before you find the necessary # of concuss's required before nuking again, and of course this changes as your warrior improves agro generation capability.

Further down the road, tanks can generate enough agro so that wizards can nearly chain nuke (big nukes, crits for hundreds of thousands) and not draw agro, or at the worst, only have to concuss every 5+ nukes to stay on the safe side.

If you haven't already, you can invest in the Spell Casting Subtlety AAs to help with some aggro.

equipping your epic 2.0 with the 2.8 aug in it will also help reduce casting agro. The 2.8 webtools/items.php?id=10445 has Empowerment of Air webtools/spell.php?id=8634 focus effect.

That epic 2.0 will be most welcome!

I would be happy to get you a copy of concussive strike rk. I if you still need. Depending on what class tank you are using I could possibly provide some extra tips for agro.
