Descent into Avernus

it's proficient with the tools used to make repairs. If the

check succeeds, the vehicle regains 2d4 + 2 hit points. 1f

the check fails, the vehicle regains no hit points, but the

repair can be attempted again using the same replace-

ment parts.

CRASHING

When an infernal war machine crashes into something

that could reasonably damage it, such as an iron wall

or another vehicle of its size or bigger, the infernal war

machine comes to a sudden stop and takes ld6 blud-

geoning damage for every 10 feet it moved since its last

turn (maximum 20d6). Whatever the vehicle str uck

takes the same amount of damage. If this damage is less

than the infernal war machine's damage th reshold, the

ve hicle takes no damage from the crash.

Regardless of whether or not the infernal war ma-

chine takes damage, each creature on or inside the vehi-

cle when it crashes must make a DC 15 Strength saving

throw, taking ld6 bludgeoning damage for every 10 feet

the vehicle moved since its last turn (maximum 20d6),

or half as m uch damage on a successful save.

CRASHING INTO CREATURES

An infernal war machine can crash into a creature by

entedng its space. The creature can use its reaction to

attempt to get out of the vehicle's way, doing so and tak-

ing no damage with a successful DC 10 Dexterity saving

throw. If t he saving throw fails, the vehicle slams into

the creature and deals ld6 bludgeoning damage to the

c reature for every 10 feet the vehicle moved s ince its last

turn (maximum 20d6).

An infernal war machine that is at least two size

categories bigger than the creature it crashed into can

continue moving through that creature's space if the in-

fernal war machine has a ny movement left. Otherwise,

the vehicle comes to a sudden stop, and each creature

on or inside the infernal war machine when it crashes

must make a DC 15 Strength saving throw, taking ld6

bludgeoning damage for every 10 feet the vehicle moved

since its last turn (maximum 20d6), or half as much

damage on a successful save.

FALLING

When an infernal war machine goes over a cliff or oth-

e rwise falls, the vehicle and all creatures on or inside

it take damage from the fall as normal {ld6 bludgeon-

ing damage per 10 feet fallen, maximum 20d6) and

land prone.

FIENDISH VARIATIONS

Devils work tirelessly to create new and more powerful

engines of war to stem the demonic tides flowing out

of the Abyss. fn addition, infernal war machines can be

equipped with more unusual weapons and armor.

ALTERNATIVE WEAPON STATIONS

One weapon station can be s witched for another, but the

infernal war machine can't have more weapon stations

than it normally has. A handful of alternative weapon

stations are described in t his section.

ACIDIC BILE SPRAYER

This hose weapon is attached to demonic organs that

produce an acidic bile that dissolves flesh on contact.

Acidic Bile Sprayer (Requires 1 Crew and Grants Half Cover, Re-

charge 5-6). Acidic bile sprays from a nozzle in a 30-foot cone.

Each creature in the cone must make a DC 12 Dexterity saving

throw, taking 40 (9d8) acid damage on a failed save, or half as

much damage on a successful one. A creature reduced to 0 hit

points by this damage is dissolved, leaving behind any objects

it was carrying or wearing.

FLAMETHROWER

Although useless against demons, this weapon is great

against flammable creatures and objects.

Flamethrower (Requires 1 Crew and Grants Half Cover). Fire

shoots out of t he weapon's nozzle in a 60-foot line that is 5 feet

wide. Each creature in the line must make a DC 15 Dexterity

saving throw, taking 18 (4d8) fire damage on a failed save, o r

half as much damage on a successful one. The fire ignites any

flammable objects in the area that aren't being carried or worn.

INFERNAL SCREAMER

A writhing humanoid torso made of melting wax juts out

from this station, with a barbed hand crank between its

shoulder blades. The figure telepathically shrieks in ag-

ony when the c rank is turned.

Infernal Screamer (Requires 1 Crew and Grants Half Cover).

The screamer's operator ta rgets one creature it can see within

120 feet of the screamer. The target must make a DC 15 Wis-

dom saving throw, taking 26 (4dl2) psychic damage on a failed

save, or half as much damage on a successful o ne.

STYX SPRAYER

This flexible hose is connected to a tank that holds 30

gallons of water from the River Styx. Each use of the

weapon depletes 10 gallons of the water. Refilling the

tank requires access to the Styx.

Styx Sprayer (Requires 1 Crew and Grants Half Cover; 3 Uses).

Ranged Spell Attack: +5 to hit, range 30 ft., one creature. Hit:

The creature is struck by water from the River Styx and targeted

by a feeblemind spell (save DC 20). An already feebleminded

creature is immune to this effect, as is a creature adapted to

the River Styx. If the target fails its saving throw and the spell's

effect on it is not ended within 30 days, the effect becomes

permanent, whereupon the creature loses all its memories and

becomes a near-mindless shell of its former self. At t hat point ,

nothing short of divine intervention can undo the effect.

ARMOR UPGRADES

An infernal war machine can receive one armor up-

grade. Sample upgrades are described below.

CANIAN ARMOR

The infernal iron used to make the vehicle was mined

on Cania, the coldest layer of the Nine Hells. An infernal

war machine with Canian armor has an Armor Class

of 22 + its Dexterity modifier. While the vehicle is not

moving, attack rolls made against it have advantage. The

infernal war machine also has immunity to cold damage

in addition to its other damage immunities, and it's im-

mune to the effects of extreme cold.
