Neither of those hacks mention furies. Think you are looking for Toxic Siphon
I think the regen from toxic siphon are probably considered “instant” and aren’t actually triggering the pain and gain back. Because the regen from Siphon isn’t a buff and it’s not a passive. Best combo for Silk is Siphon for sustainability and tide of combat for attack. It’s almost like you can’t die.
You want tide of combat, not pain and gain
