When using the Flame Runner perk on the Flame Ward skill, you gain haste upon casting Flame Runner. The Comet Rush perk on Teleport is supposed to refresh the duration of haste if haste is active when teleport is cast. It seems that this interaction does not work with these two skills.
I can confirm the same issue: I’m using “Focus” skill with “Energy Fusion” perk to gain haste and “the comet rush” perk from “Teleport” skill doesn’t refresh its duration when I use teleport while having haste.
Side note: will it add up to 4 seconds to the current duration or refresh up to 4 seconds the current duration of haste? (hint: if a 6-8sc of haste from Focus/Energy Fusion is replaced and not extended, I will be very sad!)
I have the same issue with Teleport/“Comet rush” but I’m gaining the haste through humming bee (unique sword), so it’s seems that all the interactions with haste may have the same problem.
