No idea why, but in some maps (T17), frostblink/flame dash does not save you. They simply don't work when the drowning orb is near you. Might be delirium/chilling areas, but Frostblink should be instant, even if you're 90% slowed, it should still take you out of danger instantly. Might be a bug or something.
Drowning Orbs apply -%action speed debuff. This effect stacks
additively with other slows like the slow zones from delirium (Paralysing Touch) which applies a similar debuff, causing you to reach -100% action speed which simply disables your abilities.
Additional fun fact: In Warbands league players could do this to monsters by stacking temporal chains effect and chilled ground, causing monsters to no longer be able to move or use abilities. This received a mid-league nerf by making these slow effects stack multiplicatively rather than additively so they never reach 100%.
I think this same "nerf" should be applied to Drowning Orbs and similar slows.
oooh! I was sure everything that reduces action speed already stacks multiplicatively.
Thanks for info!
