#arena 4

fast strat for the deep docks arena, not very safe but pretty fast and consistent, the shield guys will always jump if you stand far enough back (but not too far), you might need to adjust some things if the rng spawns are too desynced

This is the fastest you can do the arena however it is partially dependent on rng. For the last wave starting on the right there is a chance that the last stick bug backs up in which case if you're not fast enough the phacia will be too high to be able to spear. If you start on the left for the last wave the stick bug may do the spinning jump attack in which you will likely get hit trying to pogo. So right side start has better outcomes for bad rng.

Slightly faster way to do the first wave of this arena

Fairly consistent strats for stick bug arena, if you have 6 or more silk you can silk spear the 2nd Phacia (flower thing), if not, kill it with needle.
Sometimes the first spawn is desynced, if you're spearing you want to needle the one that spawns first. If you're needling both you want to kill the one that spawns later first, this allows the 2nd one to finish it's attack earlier so you can hit it asap.
My standing position at the start of each stick bug spawn is to force them to spawn in the middle.
For the first stick bugs I'm also making use of timing my landing right after the 2nd needle hit to get a quicker silk spear.
