To balance out the Weapon Blueprint drop % reduction we’ve made the Sporothrix and Arum Spinosa Blueprints tradable. The Sporothrix and Arum Spinosa parts were already Tradable, but it’s now one step further.

Hotfix 29.5.3

• Fixed the actual base Blueprint for the new Arum Spinosa not being in Rotation A of Deimos: Arcana Bounties. Arum Spinosa Blueprint is now in Rotation A at 18%.
