Stay TF back. Bug repellant and ghillie seems like your best option. Also, a longbow and a lot of distance. If it spots you, duck and weave MF, duck and weave!

timer for TOPOR 3 seconds so RTF AWAY AS FAST AS YOU CAN AND WHILE YOU STILL LAST

There’s nothing better than spitting acid on a creature’s face without them even knowing

I think they are found in Hunter (random guesses at this point) devourer pack and random other caves with artifacts

I once encountered this pretty much rare creature in the cave of the hunter. I had a metal shield with full durability and it was destroyed by two or three spits(easy mode btw). Obviously it was bye-bye metal shield. One thing I noticed though is that they are a bit like the titanoboa just with a spit added and could be killed with a pike. If you have a good movement speed level.
