Chest in GW:EN question

Go here http://gw.gamewikis.org/wiki/Raven%27s_Point

Under the section "Reward" it said "When opened, the Destroyer Chest spawns 1 item for each player", do we need a key for this chest? Seem like there are alot of dungeon reward type chests in GW:EN, do we need key for these chests? if so will lock pick work?

Thanks

End-dungeon chests to not require key or lockpick. Once you kill the boss it spawns and each player can open it for free.

is it repeatable? to keep getting the chests?

No. We wish. :P

Sadly, it is one-use only for each member of the party. But end-dunegon chests usually have a higher super rare drop rate then other chests in the game.

yes, you can do the dungeon as many times as you want and the chest will spawn every time you finish it allowing you to open it again.

To clarify, Hayes means it can only be opened once per character per completion of a dungeon. The chest will spawn again, each time you complete a dungeon.
