monster1 (monster desired by the NPC)
monster2 (monster the NPC wants to trade in exchange)

1st: if the player has the monster

   <property name="act10" value="translated_dialog dialog_npc1"/>
   <property name="act20" value="translated_dialog_choice yes:no,npc_willtrade"/>
   <property name="behav10" value="talk npc_slug"/>
   <property name="cond10" value="is has_monster player,monster1"/>
   <property name="cond20" value="not variable_set npc_hastraded:yes"/>

2nd: if the player hasn't the monster

   <property name="act10" value="translated_dialog dialog_npc1"/>
   <property name="act20" value="translated_dialog dialog_npc_nomonster1"/>
   <property name="behav10" value="talk npc_slug"/>
   <property name="cond10" value="not has_monster player,monster1"/>
   <property name="cond20" value="not variable_set npc_hastraded:yes"/>

3rd: trading part

   <property name="act10" value="translated_dialog dialog_npc_willtrade"/>
   <property name="act20" value="get_player_monster name_variable"/>
   <property name="act30" value="trading name_variable,traded_monster"/>
   <property name="act40" value="set_variable npc_hastraded:yes"/>
   <property name="cond10" value="is has_monster player,monster1"/>
   <property name="cond20" value="is variable_set npc_willtrade"/>
   <property name="cond30" value="not variable_set npc_hastraded"/>

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"/>
