Amulet of Accord or Evasion?

IMO, both are useless. IIRC, the Accord may be bugged, also? I couldn't find anything after a quick search in the Known Issues list, but check for yourself.

Most of the amulets are worthless, relative to the buffs you get from crafting and straight-up abilities. That said, some of the ultra rare (purple) ones can be useful. Amulets of Physical Immunity, Renewal, Rogue, Andraste's Sacrifice (with specific compatible builds), Kitty's Collar on a Reaver, Malika's Guard, Master Cooldown, Superb Dexterity or Cunning, Second Wind, and all the pieces of the Taken Shape.
