Hardest infinite in the game.
also re: stalking orb unblockable is it really convertable off of always? i didn't test it and was going off someone else's knowledge so i could be totally wrong on that one. do you have enough time to whiff the swoop and then jump up and convert off it if they just take the hit, or is it like a "you have to be expecting them" kinda deal?
edit: the mystic ray unblockable is like the task uparrow unblockable in which it relies on them falling in neutral state into the unblockable, right? meaning airdashers probably could get out but vergil is screwed?
Always convertable on a Stalking Flare hit on reaction. My main team for about 4 months was Firebrand/Dormammu/Shuma-Gorath, so I speak from extensive experience. You usually superjump after them, j.H, and then Bon Voyage. You do have to react very quickly though, as you need to swoop, j.S cancel, superjump, and j.H.
Mystic Ray unblockable works on incoming opponents who have no aerial mobility, as the completion of a lockdown with Stalking Flare (the timing is normally tight; this makes it easy), and after a knockdown in the corner, it will also create an unblockable against forward techs. Whenever I got a knockdown with Firebrand and I couldn't afford to Stalking Flare unblockable and didn't want to TAC, I went 50/50 between Dark Hole and Mystic Ray. If they back tech, Dark Hole creates an unblockable. If they forward tech, Mystic Ray creates an unblockable. I usually use Mystic Ray because people like to tech forward and if they tech back it still creates solid pressure, whereas Dark Hole does not.
If Shuma-Gorath weren't a complete piece of shit in this game, that would still be my main team.
There are actually several hypers that give Firebrand great unblockables. He is a very underexplored character.
