Large mystery box is the final reward for helping with The Lost Sword activity in Falador Park. It is rewarded automatically when the player's personal contribution has reached 100%. The message You receive a mystery box for reaching the maximum personal progress! is also given.
Opening the mystery box will reward the player with items from Treasure Hunter and/or commendations for the Invasion of Falador event.
If the box is destroyed, players can reclaim it at any time by speaking to Darla.
Ironmen cannot receive any of the rewards granted upon completion of this event.
