Get Party Monster

Let's say you want to add a tech to a monster (NPC). Eg. the NPC Rockitten needs to know Canine, but Rockitten is the 4th monster (equal to 3rd slot).

   <property name="act10" value="add_monster rockitten,20,npc_slug,27,10"/>
   <property name="act20" value="add_monster vivipere,20,npc_slug,27,10"/>
   <property name="act30" value="add_monster budaye,20,npc_slug,27,10"/>
   <property name="act40" value="add_monster rockitten,20,npc_slug,27,10"/>
   <property name="act50" value="add_monster nut,20,npc_slug,27,10"/>
   <property name="act60" value="get_party_monster npc_slug"/>
   <property name="act70" value="add_tech iid_slot_3,canine"/> ---> iid_slot_3 followed by Canine
   <property name="act80" value="start_battle player,npc_slug"/>

Battle Among NPCs (the player watches without interacting)

(eg npc_maple vs npc_apple)

   <property name="act10" value="create_npc npc_maple,0,7,stand"/>
   <property name="act20" value="create_npc npc_apple,0,8,stand"/>
   <property name="act30" value="add_monster chloragon,3,npc_maple"/>
   <property name="act40" value="add_monster rockitten,3,npc_apple"/>
   <property name="act50" value="start_battle npc_maple,npc_apple"/>

separate event, multiple endings, if npc_maple wins

   <property name="cond1" value="is variable_set battle_last_winner:npc_maple"/>

separate event, multiple endings, if npc_apple wins

   <property name="cond1" value="not variable_set battle_last_winner:npc_maple"/>

separate event, multiple endings, if no-one wins

   <property name="cond1" value="is variable_set battle_last_result:draw"/>
