The Burrower's Shell

The Burrower's Shell is a trinket that absorbs damage.

This item is dropped by Ouro in the Temple of Ahn'Qiraj in Silithus.

It does not absorb enough damage to qualify as a main tank's trinket. Off-tanks or secondary tanks may consider it as a supplement to emergency abilities like Last Stand. Casters may use it in encounters where adds interrupt their spellcasting.

Where this trinket really shines is in PvP. While it lacks the dodge bonus of the Arena Grand Master reward, its far shorter cooldown (3 min vs 30 min for the Arena Grandmaster) makes it perfect as a defensive measure.
