Thorn (Year 1)

Thorn is an exotic hand cannon. It used to be acquired by completing the exotic weapon bounty A Light in the Dark. It is currently only obtainable from legacy engrams.

Thorn is one of the Weapons of Sorrow that have been constructed using the Hive's forbidden power. It was augmented by Dredgen Yor after he delved into the dark mysticism of the Hive.

Trivia

 * Cabal Phalanxes can be injured by the Mark of the Devourer damage over time effect even if the dart hits their shield.
 * Thorn has overpenetration even if Mark of the Devourer is not yet unlocked.
 * Shields do not regenerate while Mark of the Devourer is in effect, making this a good weapon against enemies with high recovery rates.
 * Mark of the Devourer used to last for 5 ticks after the most recent shot, but the effect did not stack. In Update 2.0.0, Thorn received a nerf that reduced the amount of DOT received from Mark of the Devourer, but it now stacks for each shot landed.
 * Thorn received a buff that increased the magazine size from 6 to 9, increased the reload speed and stability, and increased Mark of the Devourer's effects on PvE enemies.
