Interestingly, Roland actually prefers the downgrade to the original. This Disc softens up big enemies and still allows him to get the killshot for the clue, and it's an outright testless clue when used on small enemies. Other than Hallowed Mirror (maybe), I don't think there's another accessory I'd rather have for Roland at level 0.
Disc of Itzamna
When a non-Elite enemy spawns at your location, discard Disc of Itzamna: Automatically evade that enemy or deal it 2 damage.
At 3 Resources, this is a bit expensive, since that (and the slot) could have gotten you Tooth of Eztli or Grisly Totem, always assuming you can't take Crystalline Elder Sign or Rabbit's Foot. On the other hand, Seeker isn't exactly drowning in enemy control, so this isn't terrible, just a bit overshadowed by other choices. It's the kind of thing that you upgrade out of fairly quickly once your core XP plan is realized.
If I use the disc on a deep one that is spawning on me does it ever engage me or does the when interrupt it fast enough to prevent the enemy to have been considered engaged with me? (either by evading it or dealing it 2 damage and killing it)
