Cuirass and Greaves
If you have reached rank four (Mouth) in House Telvanni, you can get a quest from Therana in Tel Branora's Upper Tower. Talk to her, then go to the Tower of Dawn in Ghostgate. Ralyn Othravel is on the second floor. It is possible to pickpocket the bow from him, otherwise you'll have to fight him. Take the bow back to Therena and select the option to receive payment.
