Proving After Dark

A series of "unofficial" fights in the Orzammar Proving which you can initiate by speaking with the Proving Armsman.

Each fight consists of your team versus another team of 4 yellow opponents -- usually 2 melee fighters, an archer, and 1 other opponent. The other opponents you face are: a blood mage, a champion, an arcane warrior, and a champion with an elven healer.

Each fight gives you 12 silver, and winning all 4 gives you the Blood Ring, which also unlocks a Codex entry.
