/curse

Command	Effect
/mxt curse list [<target>] (= /curse)	Lists the curses a holder carries: name, stacks, and the ticks left or "never expires". Without a target it looks at you, and it needs no permission.
/mxt curse apply <targets> <curse> [<stacks>] [<duration_ticks>] (= /curse apply …)	Applies a curse (needs the gamemaster permission); stacks is 1–256. It goes through the same transaction content uses: conditions, stacking and on_apply behave normally, and a definition that is disabled through #mxt:disabled or deleted is refused with the reason. duration_ticks can only tighten the definition's own length.
/mxt curse remove <targets> <curse> (= /curse remove …)	Removes it with the explicit reason (needs the gamemaster permission). This is also the only way off for a disabled or deleted definition.
/mxt curse cleanse <targets> <tag> (= /curse cleanse …)	Cleanses by mxt:curse tag (needs the gamemaster permission), with the same cleansed reason an antidote uses; a frozen instance refuses and says why.
