Tunneler. The worm can burrow through solid rock at half its burrow speed and leaves a 10-foot-diameter tunnel in its wake.
Multiattack. The worm makes two attacks: one with its bite and one with its stinger.
Bite. Melee Weapon Attack: +14 to hit, reach 10 ft., one target. Hit: 22 (3d8 + 9) piercing damage. If the target is a Large or smaller creature, it must succeed on a DC 19 Dexterity saving throw or be swallowed by the worm. A swallowed creature is blinded and restrained, it has total cover against attacks and other effects outside the worm, and it takes 21 (6d6) acid damage at the start of each of the worm's turns.
If the worm takes 30 damage or more on a single turn from a creature inside it, the worm must succeed on a DC 21 Constitution saving throw at the end of that turn or regurgitate all swallowed creatures, which fall prone in a space within 10 feet of the worm. If the worm dies, a swallowed creature is no longer restrained by it and can escape from the corpse by using 20 feet of movement, exiting prone.
Tail Stinger. Melee Weapon Attack: +14 to hit, reach 10 ft., one creature. Hit: 19 (3d6 + 9) piercing damage, and the target must make a DC 19 Constitution saving throw, taking 42 (12d6) poison damage on a failed save, or half as much damage on a successful one.
my dm didn't want us to engage so we engaged but from a cliff but then dm made the worm run so we stoped
Make sure you walk without rhythm if you're trying to avoid these things
Dune, anyone?
Walk without rythm...
purple funny
The spice must flow
Wow....this is one nasty critter. Its stinger deals insane amount of damage from its poison, and it has a near impossible saving throw against that poison. Its bite can do a great amount of damage, at the same time swallow you whole, and it can couple each of these attacks every round with each other... This is a perfect way to chew through your characters very quickly.
I love this monster!
Be a Wizard, get proficiency with Poisoner's Kit, cast Simulacrum on yourself (or cast it through Wish to avoid the huge cost of the components), have your simulacrum cast Magic Jar and posses the worm, destroy the jar, (relatively due to the ability check on harvesting) safely harvest as much poison as you want, making your Rogue love you, getting a CR 15 pet/mount and becoming a super-rich criminal overlord, all in a good day's work.
Unfortunately this particular method would not work for two reasons:
1) your simulacrum is made from a spell, and therefore has no soul. As the magic jar spell description makes clear, the caster needs a soul for the spell to work
2) the magic jar spell only works on humanoids, "You can attempt to possess any humanoid within 100 feet of you that you can see"
However any arcane caster (not just a wizard) could attempt to use the wish spell that you used to circumvent the hefty cost of the simulacrum spell to just take control of the creature directly, this is of course up to your DM's discretion however.
It wriggles and squirms just like a normal earthworm.
Keeps things simple yet super effective with the classic vomit! Mechanically, a purple worm vomit ability should be similar to an adult black dragon. That way, even flying creatures aren't completely safe from the worm.
Purple worm: *appears*
Most players: Ohhh nooo not a purple worm!!
Poisoners: *pushes up anime glasses*
Nasty!
My player used to be a lawful good clerik warforged. He was super delighted charecter that never did damage and allways heal. But now he splitted the party a Dungeon masters greatest weakness soooooooooooooooooooooooooooooooooooooooooooooooooo PURPLE WORM!!!!!!!!!!!!!!!
Profinciency bonus
Aw, yes. I recently was allowed to have one of these as a pet for a Strixhaven game we are starting. I'm playing a wood elf alchemist spore druid enrolled in witherbloom. I was allowed poison immunity sense I was originally trying to play a yuan-ti pureblood, but he said instead of magic resistance I could add the wood elf template on top of it. I named my purple work Richard. He lives in the detention bog. I am going to open up a potions, poisons, and perfume shop. The only rule is I can't use Richard for any important story based battles. I just love the idea of my character saying (in a British accent) "Would you all like to meet my friend Richard" and just a giant purple worm coming out the ground.
The walking speed would be for when it isn't actively burrowing. So while in combat in the open or moving through open terrain, such as the surface in the desert.
