I shall elucidate the claiming mechanismo of the hibbity jibbity. First, you make-a macro thata looks like this:
/item "Item Name" <stnpc>

thena you target a monster that's on one side. Or on the Other side! of the ???. Holda left or right, so when the ??? spawns, your cursor goesa whizzbang and default to it right quick. Hit entra.
