The blue dragonhide body (t) is part of the blue dragonhide trimmed set, along with blue dragonhide chaps (t). Its stats are identical to a blue dragonhide body, but it has a silver trim. To wear a blue dragonhide body (t), a player must have 50 Defence, as well as completion of the Dragon slayer quest.
It is also a possible reward from a hard clue scroll. Unlike normal dragonhide armour, it cannot be made with the Crafting skill, nor can trim be added to a normal blue dragonhide body via any method.
