the "can end" does same job as "arg1007" from old AMS, its 0 by default, you dont need to add it.
most of the time its useless, since only "fake dead ringer" ability use it, afaik.
what does it do? if true and boss has a consistent rage, it will call internally "MyRage_EndAbility(...)" which should stop the ability or do anything else, up to the plugin creator.
