Stacked heavy glass made easy
Placing a worn gi or a glass armor on the ground by picking up the other, will remove its next instance that would have otherwise been conjured. That makes it possible for you to conjure multiple heavy glass without the intermediate gi and glass armors. The effect of wearing multiple heavy glass, although not reflected in the sprite, is a genuine increase in the durability. Shown here is 12 hits of heavy glass.
The easiest way to achieve this is a shadow conjurer, but to get 6 conjures requires only 3100 gold in all zones mode, and if you enter the conjurer wearing one of gi or glass armor, it is doable in only 5 for 1500 gold.
