It's faster then us, and now it has uber eye sight. If we take the rock, it nabs us. How can we fight it when it's on the ceiling.
It does not have uber eyesight, it has good lowlight vision but still not the best of eyesight when say compared to a human or bird or whatever in terms of detail etc. You could still conceivable hide from it if you could get out of line of sight first and then sneak back for sneak attack.
If possible, activate sem-clear DAZZLE CAMOUFLAGE mode. (Look it up if you are unfamiliar with it)
That's the whole point of our many colours, after all!
It shouldn't be able to accurately pounce on us in that situation.
There is insufficient light to activate special ability scintillate, and we do not yet have the ability to generate our own light.
Pretend the spider is a japanese school girl And TENACLE MURDER it.
You'd need at least 3 otherworldly spirits possesed blobs, both with mushroom tentacle upgrade, working in concert.
Bunch of conflicting commands by two people plus some commands by others
Blob is gripped by indecision as to its best course of action and how it could rescue its poor braindead child(this concern was of course at the forefont of its mind, excellent parent that it was.)
The spider takes this opportunity of distraction on the part of the Blob to attack! It jumps down from the ceiling, aiming for Blob!
Blob manages to barely dodge the spider!
KILL KILL KILL
Contract into a ball and use some of our mass to send out a long tentacle to grab one of the spiders legs. Then RIP and TEAR. then consume.
A sudden inspiration dawned in your mind. It was as if all your experiences up to this point have somehow been distilled into a a entirely new and powerful concept. Tentacles at pseudopods are all good and well, but what if you were to shoot out SPIKES? All shall fear your power!
New power gained: Spikes!
((The rng favoured you, seriously, natural twenty, not kidding.))
