What is the behaviour ingame?

Tested in PvP and with Malevolence, the duration of the base poison increased from 4s to 4.8s.

What is the behaviour in Path of Building?

PoB is not scaling the duration as it does not have the poisonIsSkillEffect flag on the skill. But if you add the flag then all sources of duration will scale the poison duration which is incorrect. Increased Duration Support does not scale the poison duration, only the effect from Malevolence does

Screenshots

Start by tracing Path of Building's poison-duration calculation and the skill-effect flag handling described in the issue. Verify the Arakaali's Fang spider behavior against the linked build and ensure Malevolence scales poison duration while Increased Duration Support does not; confirm the result with the relevant calculation checks.
