I have been extremely lucky this season. I have gotten three triple hits so far. Shako, Doombring, Ring of Starless Skies. The rest of my gear has double hits. Pure luck.
Last season, I spent 140K Obducite trying to get a triple hit on one item and never got it. All three of my triples this season happened in less than ten resets. I’ve run out of Veiled Crystals on several occasions. I’ve had to resort to opening the equipment chest in Infernal Hordes just to scrap that equipment.
