problem is that the items (x) and (y) are droped by nme's so i cant just select them off map

please help

Events

• Player picks up an item

Conditions

• Quest is not complete
• Player has item of type item X
• Player has item of type item Y

Actions

• Complete Quest (either do actions here or run a seperate trigger)

You may have to do some fancy stuff with the conditions if the player can have multiple heroes, but all you will need is a little brains and a lot of OR's :).
