if youre above 6 soul in the tunnel, you can save future nail hits of soul by shooting a fireball backwards to instantly kill the husks before proceeding to do the normal strat for ghusk. unfortunately, there is higher chance of missing geo from the husks as you tend to kill them farther right (idea from @magneticpizza)
22nd devout 1 soul strat
saves ~.1 to normal 2 soul devout optimally, and is way easier to greed, so on avg about .15+ timesave (usually higher really)in my experience,
frameties devout airwalk
u can go neutral as soon as u pass the devout to make lantern pogo easier, its same speed
Better movement for the Hell room lever skip which let's you get the soul jar for no timeloss. Dashes leading up to the dash slash save around 0.15, and the rightside walljump saves another 0.15. This also means you are fast enough to still get the wcs which can save up to an additional 0.6
7Soul reroute + strat change for trap bench. Left enemy in the first room saves what looks to be about .5 to old strats, right enemy loses about .2 to left enemy. Be far away from the petra when you slash + jump up to it to increase chances of double. May be better to get the extra soul leaving Uumuu, needs more labbing.
14With the 2 hits of soul from previous strat, this gives you the one net hit of soul you need for firebell. Saves .8 over triggering devout attack, then parry pogo + backhit
Consistent setup to have full soul for the devout in beast den.
After the two dashes to land you on middle plat, do a dash followed by a neutral dash to not go too far left & not activate the camera movement.
Then you face right, do float inputs, turn left, jump downdash turn right, side slash twice (keep track of your soul, might need a third time if unlucky of weaver rng), then dash left and proceeed as normal.
This loses .7s optimally, but gives you enough soul to 3fb the devout in beast den, needing only two nail hits to kill it. This saves ~2s (no need for damagetanks or nail hits after the tank), so a net save of 1.3s. This also gives you two soul, allowing for next strat...
If you need 3 hits of soul on the way to Watcher Knights, then you can do this strat to get 3 hits without losing too much time. Haven't timed how long it takes compared to normal strat, but getting the soul can be worth sometimes. You need to hit the rava immediately after the 2nd wall jump otherwise he'll be too far away to get the 2nd hit with the upslash. As long as you hit him with that first nail hit you will never dash into him. Not too difficult to do with some practice.
