I ran a T4 Temporal Sanctum and the boss dropped exactly 1 unique and 2 exalteds. I understand the quantity is randomized, but this is way too low. The modifier states “horde” but this is far from it.
Had you already picked up the glyphs & runes? I agree that that’s not exactly what I’d think of “substantially more” exalted weapons.
Horde of glyphs, the ones you have already picked up, right?
Sometimes the modifiers is the boss dropping weapons or exalted gear, and you will notice it’s substantially more than these 3 itens.
