There's a new way to pick up prizes in Treasure Hunter. 00:00 Game Time on 10th May until 23:59 Game Time on 15th May, get hunting for Buried Treasure.

For that duration, your Treasure Hunter interface will be transformed into a grid-based map, and you'll open chests by clicking on squares within it.

Each square contains at least a normal chest, but 6 per grid will contain a special chest, containing a trove of 4 or 5 prizes.

These come in four types, which can contain different types of items and the amount left to find on your grid will be displayed at the side of the interface.

Here's what each chest type may contain:

Experience Chest	Protean Chest	Skilling Chest	Antique Chest
Meteorites	Protean bars	Springs	Gold coins
Lava lanterns	Protean hides	Spirit gems	Pulse cores
Smouldering lamps	Protean traps	Portable packs	Prismatic lamps/stars
Hydra lamps	Protean memories	Dungeoneering tokens	Dragon ceremonial outfit
Celebration lamps	Protean cogs	Skilling dummy packs	Queen's guard outfit
Prismatic lamps/stars	Protean planks	Combat dummy packs	Wicked Hood teleports
	Protean logs	Pulse cores	D&D tokens
	Protean packs (s/m/l)	Silverhawk feathers
		Magic notepaper

Note that the antique chest will always contain at least one piece of these two outfits, unless you already own both – in which case it will contain rare tokens.

There's also a chance that any of these above chest types will contain a special prize: a Treasure Chest rest animation, a held Treasure Map item, or a much rarer chance to get a lucky item (including retired ones).
