I'm horrible at converting things from xx to 5e.
If someone could assist me please I need the Bebilith from 3.5 converted to 5e for this weekends game. I know it's short notice and I'm sorry!
Also if possible could the one who does upgrade it to CR 17-18 ish please.
Thanks in advance.
A quick and dirty conversion. The body configuration doesn't really lend it to doing more than 3 attacks. As such this would fit nicely into being a CR 11 monster. Fitting it to CR 17 means giving it even more attacks to do even damage, or turning it into a bag of hit points, which can slow down combat if you do not have some heavy hitters. It is also vulnerable to
banishment (even with magic resistance). I lowered the bag of hit points syndrome by giving it legendary resistance (I assume the elevated CR means this is a "boss"), and an extra claw attack as a legendary action.

Web (Costs 2 Actions). The bebilith fires a web at a creature within 30 feet. The creature must make a DC 18 Dexterity saving throw, becoming restrained in thick webbing on a failure. As an action, the restrained target can make a DC 18 Strength check, bursting the webbing on a success. The webbing can also be attacked and destroyed (AC 10; hp 14; vulnerability to fire damage; immunity to bludgeoning, poison, and psychic damage).
