Tip: The Procedural Encounters table will generally produce homogenous encounters with only a single creature type. Although it requires more dice rolling (and some creative interpolation to explain the results), you can quickly generate mixed encounters by rolling twice and halving the number of creatures of each type appearing (round up).
You may discover that it’s actually easier to improvise creative encounters by generating mixed results, because the pairing of different devil types will spur your creativity in explaining what they’re doing together.

ENVIRONMENTAL ENCOUNTERS

| 10-12 | Oppressive Conditions |
ROCKS OF THE DAMNED: Some of the rocks in Avernus seem to have tormented faces etched into them.
BONEFIELD: A field of bleached bones lying half-buried in the dunes or choking a razor-sharp ravine These are remnants of some ancient battle. (Avernian bonefields often feature titanic skeletons that will tower over the PCs.)
AVERNIAN FIREBALLS: Travelers in Avernus are periodically plagued with balls of flaming energy that spontaneously erupt without apparent reason. They inflict 5d6 fire damage, with a DC 15 Dexterity saving throw for half damage.
INFERNAL WRECK: 1d3 wrecked infernal war machines. The PCs can likely scavenge parts from them. There’s a 1 in 6 chance that the machine can be repaired without completely overhauling it.
OPPRESSIVE CONDITION: Trigger an oppressive condition, as described in Part 7B. This will exist in addition to any oppressive conditions already present.
AVERNIAN WARLORDS
See Part 7E: Warlords of Avernus for more details on the warlords. You can roll on the table below to randomly determine which warlord’s faction has been encountered. There is a 1 in 4 chance that the warlord is present for the encounter, otherwise it’s just an appropriate squad of their gang members (most likely riding infernal war machines).

Do you recommend giving Infernal Warmachines to some or all the creature that could use one?
Because the players will have one really soon after leaving Hellturel, and since those machine have a speed of 100ft’ they can easily roll away from every encounter.
