I was running Heroics with some guildies the other day, and we were in Slave Pens. I can remember doing this instance pre-70 on Normal, and thinking it was abig blah, to tell the truth. Anyway, Heroic isn’t much better, but we got through it OK.

The end boss decided that he was going to drop his Eye, which gives the following stats:
Equip: Increases damage and healing done by magical spells and effects by up to 37
Equip: Your harmful spells have a chance to increase your spell haste rating by 320 for 6 seconds

The +spell damage is nice, and is the reason I rolled on this trinket, even though it’s only a rare. I haven’t had a whole lot to do with +spell haste until now …

I’m still hoping to get out to Dr Boom and do some tests with this trinket, test it’s proc rate for myself, etc, but here is the lowdown so far, based off running Heroic Underbog last night and Gruul’s on the weekend:
It procs off Shadowbolt hits, Dot hits (not ticks, as far as I can tell), anything that can be called a “harmful spell”. Lasting only 6 seconds, it changes my ShadowBolt cast time from 2.5 seconds to 2.06 seconds. Not a great deal, I hear you say, but that’s .44 seconds that can add up over time.
The proc rate is kinda low. When I get to have a go at Dr. Boom, I’ll have a better idea of it’s proc rate and DPS increases/decreases.

Looking in my bank now, I have 4 trinkets that are sitting there. I can’t bring myself to throw any of the them away, because some are situationally useful. There’s one that’s just an on-use +spell damage, one that increases my +spell crit rating and gives an on-crit-hit chance to increase spell damage by 225, and my Violet Eye Trinket, with +36 stam and +45 arcane resistance (made for Curator).

It’s all a juggling game, trying to work out what fights you might be facing, and which trinkets will help the most. I normally take the trinkets with me to every fight, just in case, but it’s eating into bag space.

Has anyone had any experience with Quag’s Eye? Is it worth holding onto, since I will be (eventually) getting some other +spell haste gear? Or shoudl I bench it until later on in the game/permanently?
