Bit of forewarning that Hellsgate snapshots your current position until you reappear and has no iframes. Be careful using it when avoiding AoEs or cleaves in fights. Regress also has double the range as Hellsgate. 30y.
I very much enjoy the Castlevania Dracula vibes I get from it with warping behind the boss and back again. It's very *NOTHING PERSONAL KID*.
Dbl harpe is possible if you back into a wall which I like if you need to be at range for a while.
I'd treat it like Elusive jump But with more control.
I still think Macro'd Shukuchi is still the best dash in the game. Hellsgate is great because of the fakeout you can do. It's a monster in PvP both as an ambush and as an escape option.
