Traits

Proficiency Bonus

+3

Hold Breath

The wurm can hold its breath for 1 hour

Limited Flight

The wurm can only fly for up to 1 minute at a time. If it ends its turn in the air after 1 minute of consecutive flight and nothing else is holding it aloft, it falls.

Noxious Resilience

The wurm has advantage on saving throws made against harmful gases and vapors (such as the effects of a stinking cloud or a green dragon's poison breath).

Tunneler

The wurm can burrow through solid rock at half its burrowing speed and leaves a 5-foot-diameter tunnel in its wake.

Volcanic Body

The turm sheds bright light in a 10-foot radius and dim light for an additional 10 feet. In addition, whenever a creature enters the area within 10 feet of the wurm for the first time on a turn or starts its turn there, the creature takes 3 (1d6) fire damage.

Actions

Multiattack

The wurm makes two melee attacks.

Bite

Melee Weapon Attack: +7 to hit, reach 10 ft., one target. Hit: 9 (1d10+4) piercing damage plus 5 (1d10) fire damage.

Molten Spray (Recharge 5-6)

The wurm exhales molten metal in a 30-foot line that is 5 feet wide. Each creature in that line must make a DC 15 Dexterity saving throw. On a failed save, a target takes 38 (11d6) fire damage and its speed is reduced by 15 feet. If a target's speed is reduced to 0 by this effect, it becomes restrained. A creature can take an action to scrape or wash off the metal, ending the effect. On a successful save, a creature takes half as much damage and its speed isn't reduced.

description

Occasionally, a lava wurm will live long enough and grow their vestigial wings large enough to become an elder. These creatures are an order of magnitude more dangerous than the young wurms, as their small but now functional wings allow them to more readily and swiftly follow their prey through molten rock and the open air. With their sheer bulk and love for fine granite, elder lava wurms are an infrequent but greatly feared invader of Heavensteppe, usually requiring many Steel Hawk lives to drive away.
