Disintegrate's Flame burst / spreading flames / ignite damage unaffected by disintegrate's nodes

Bug Reports

Main Issue

Any of Disintegrate’s Increased damage nodes do not affect its secondary effects, such as Spreading Flames and Flame Burst, and even Ignite, making them completely unusable.

This is almost certainly a bug, as any other skills, such as in case of fireball, ailments and spreading flames do receive damage bonus from its own skill trees.

Expected Behavior

  1. At the VERY LEAST they should be affected by Disintegrate’s increased damage multipliers, such as from Searing Plasma Node.

  2. They should almost surely be affected by disintegrate’s stage bonus. for example, Flame burst/Spreading flames inflicted while it’s on its 2nd/3rd form, should do that much more damage.
