Bor can be first encountered at the Last Light Inn, where he patrols the back of the inn itself. Provided the Tiefling refugees survive Act One, Bor can be found chatting with Mirkon in the bedroom.
If the party successfully prevented Flaming Fist Marcus from capturing Isobel at the Last Light Inn, and once the Nightsong has been freed from her cage and is headed for Moonrise, Bor will follow Jaheira to Moonrise Towers. However, Bor is killed during the fight against Absolute forces before the party can arrive. His corpse can be found within Moonrise Towers itself, down the staircase leading down from the entrance, right in front of Disciple Z'rell.
Normal weapon damage
Throw all caution in the wind to gain Advantage on your melee Attack roll.
Until your next turn, you have Advantage on all Attack Rolls, but enemies also have Advantage on Attack Rolls against you.
Bor has an identical one-to-one copy of itself called Arthus that only spawns when the party returns to Last Light Inn, immediately after freeing the prisoners from Moonrise.
Arthus and Bor, however, do not share the same voice actor.
As of Patch 6, despite having Extra Attack, Bor is not able to attack twice during his turns.
