Item:Commendation of Heroism

Commendation of Heroism is a collectable item added with Update 14.

It drops in Caught in the Web raid end chest with very, very low drop rate (less than 1% suspected on each of 6 end chests, on Epic Normal). It is unknown if this Commendation appears on special 20th reward list of the raid or not. 

Commendation indeed is BtC and also requires tier 3 Purple Dragon Knights favor (375 favor points) to be redeemed.

Cormyrian Dragon Armors
You will need 3 of these to get any kind of "Cormyrian Red Dragonscale Armors" and "Cormyrian Green Dragonscale Armors" (see Dragonscale Armor for details).

Planar Conflux upgrade
Of relic weapons found in the Caught in the Web raid, currently only Antipode (Handwraps) requires 3 Commendation of Heroism. Feather of Sun stated this is not WAI and all weapons will require Commendation with next Upate.
