an easier setup for wcs than scruffy's and w/o having to learn any timings
stop holding jump once you're above the lantern, then when you're far enough right to pogo the soul container tap left and pogo neutral, buffer the jump and dash when you're around the height of the crest in the door(its better higher than lower), if you're too close to the door you can do a wiggle after the jump
once you hit the ground jump(don't buffer or you'll jump in the wrong direction) and immediately neutral, this should put you close enough to talk to the shaman, if you're not you're dashing in the door too low
i haven't timed it but this is probably slower than scruffy's bc they dash only once
