Armor Expander Box

The Armor Expander Box opens to a slot-expander that adds extra enchant slots to a piece of armour.

Apply the expander to an armour piece to unlock room for more enchants: it usually grants +1 slot, with a chance to roll +2 slots instead. More slots means more armour combat enchants or mining enchants on armour stacked onto a single piece of gear.

Where to get it: an uncommon find in the Fund III, Fund IV, and Fund V lootboxes from the Community Fund, in the Season 1 Crate jackpot, in the KOTH Lootbag, from clue caskets and rank kits, and from the Erebus Guards of the Pit.

Bad luck protection

The Erebus Guard drop is covered by /rngmeter. Track the Armor Expander Box and every guard you kill fills its meter; fill it and the box is guaranteed. Every Erebus Guard chase drop is selectable from the start (you don't have to pull one first to unlock it), and the meter's progress line prints every 25 kills rather than every kill.
