It does! Standard red lock is 7 training stage blocks. With CSb it becomes 10. The buff lasts indefinitely until PG is staggered/downed, but it's not exactly hard to charge it up again and reapply, and there's no limit to the number of times you can do so. I'd like to point out that Sub's trajectory can be altered at any point after firing. You don't need to hold a direction before you input AB, and you can change direction during the active time if you want. It doesn't just move diagonally, but rather wherever you choose to point it! Horizontally for 4/6, vertically for 2/8, and diagonally for 1/3/7/9. Great for anti-melee. 5BC's spread is totally random so it's not the most reliable tool in PG's arsenal. I've had them line up in a perfect vertical before as with Matsunaga's sub, line up in a perfect horizontal as with Ridden's, and go everywhere in-between. If the spread is tight enough they can chain explosions from the first mine to drop and trigger while still airborne, in rare cases missing whatever you're aiming at. They can be shot out of the air as well, and they still chain explosions if that happens; if intercepted early enough it can backfire and stun PG instead. 8BC does a windup and throws them a greater distance (9-10 training blocks) with a wide horizontal spread. 2BC jumps backward and throws them quite close (1-2 training blocks) with a quadrilateral spread. The latter's movement does not cut tracking, although it's still great for self-defence. ABC has super armour during the first stage so you can throw that out to surprise people who get in your face, but it has absolutely no cut resistance (and that pose at the end... ugh) so expect to be punished if you're noticed doing it. The 8b derivation from your 5 and 4/6 melees is totally awful and you should avoid it unless your enemy's partner is down or something. Once it's started you can't BD out or step cancel, and it barely moves. Rocket punch [A] is good for a quick knockaway. Still shouldn't ever melee in this thing XD

Just tested it to confirm. Overcosted by 1000, came back with 470HP in Odysseus mode with BC at 0 and on full cooldown. Overcosted by 2000, came back with 240HP in Odysseus mode with BC at 0 and on full cooldown. Overcosted by 2500, came back with 120HP in Odysseus mode with BC at 0 and on full cooldown. BC's "HP" did not affect the overcosted HP values of the suit. They're typical of a 700HP 3k. When Penelope was reapplied after each death it was perma (BC gauge vanished), and it did not purge again for the rest of that life regardless of how much damage was taken.

Sub is soooooo good. You can use it to help with your zunda since it's more boost-efficient than BD canceling. It also turns you around with the initial movement to get on-angle and you go into freefall right after the shot (and a slight pause; the wiki is totally right about it being punishable). If there's no ammo you'll still move and fall, though it can't be used in overheat. You can cancel into it from pretty much everything you have except 8B, BD8B, 2B and your BC activation and movements. Can even cancel into it from your assists! It doesn't cut tracking sadly, and a neutral Sub will send you directly towards your target so you have to watch for that. BC movements don't seem to cut tracking either which is annoying.

Correct me if I'm wrong, but I'm pretty sure that once the flight armour is purged and reapplied from Odysseus mode, it can't be destroyed. Even if you take 280 damage in Penelope mode after reapplication, it won't purge again. Both modes have constantly reloading Mains. They don't have to be emptied first like you would expect from reading "n rounds until reload". Both Penelope and Odysseus' Subs on the other hand do have to be emptied before they start reloading. A neutral BC in Penelope mode always moves to the left. It does not cut tracking. While you're purged and in Odysseus mode none of your Penelope armaments will reload except your Main. If you respawn in Cost Over you'll do so in Odysseus mode, regardless of what mode you were in when you died.
