Does it make corpse tendrils faster?
That is good question. Haven’t been able to test this yet.
I could be wrong, but I had seen where it at least I last season, if affected things like the activation time of tendrils and the pulse rate of BCE. It gets a much higher bonus because it’s extremely limited in what it affects
Corpse attack speed is attack speed, that only applies to abilities with the Corpse tag.
Attack Speed does improve the animation speed of Corpse Tendrils.
Corpse explosion and if you have the corpse attack too from the item that does not make them explode but randomly attacks targets and tendrils speed.
