Yes, already messing with trinkets, but for now (since we can only do heroics), the Entropic Skardyn Core from Rookery is pretty awesome. Basically a roughly~10% int bonus for 15 seconds when you grab the black orbs. I figured it would be annoying to run around and collect the bits, but they actually persist for quite a while (30 seconds from spawn to disappear and they don’t move) and there can be multiple out at once (had 3 up at once). The effect doesn’t stack, but you can run from one to the other, to the next pretty easy and keep the buff up for a long time (15 sec per grab). It also has some sick +crit on it. They spawn anywhere from right next to you, to like a mile away, so gotta zoom out your view. Probably could use a weakaura to track if they are out and how much time remains on the buff.
I don’t see it on any of the Mage BiS charts, but I’m guess because it’s from a dungeon that isn’t going to be in the rotation for S1, so the trinkets there will just run away with ilvl and outclass it fast. But I’m wondering is S2 will see it get some play.
I’ll quickly get pigeon holed into hunting for a trinket/or piece of gear (I still remember you…Balefire Branch, ugh). I am cautiously excited about Delves, though my experience with them so far (up to Tier 3), has been underwhelming.
