These are things that seem to be relatively easy to do, so will be part of the current cluster of combat updates I'm working on.
Make bombs, Spears and shields subplugins
Automatically put new players in the combat system
Remove boosters (they're obsolete)
Have a tool to make foe attacks much easier
Weapons can be assigned into the "global" attack reason slot, or Hosts can create new slots with conditions attached to them to assign weapons to
On that note, add in a conditions object that applies to the specific battle
All foes in room defeated trigger, fires after all specific foe deaths
Foe spawn subplugin -- a chance for foes to spawn when you enter a room, maybe also attack you automatically, up to a certain limit. These can be set on global, room, room category and conditional bases.
