I only have enough coins for one of the two. MIDA is the only exotic weapon that I don't have. This would essentially complete my collection (once I finish the Pocket Infinity bounty). I've heard mixed reviews of it as far as usefulness goes. On the other hand, I've been stacking legendary and exotic gear for my Warlock that's currently sitting at Lvl 15. I hear Obsidian Mind is the crown jewel for Voidwalkers in PVE and missed out on it last time Xûr sold it. I've already got Bad Juju and sure do I love me some supers. What say you, guardians? MIDA Multi Tool or Obsidian Mind?
