Tunneler. The zulerin sentinel can burrow through solid rock and skymetal at half its burrow speed and leaves a 10-foot-diameter tunnel in its wake.


Actions

Multiattack. The zulerin sentinel makes two attacks with its tentacles.
Tentacle. Melee Weapon Attack: +9 to hit ( 1d20+9 ), reach 15 ft., one target. Hit: 22 ( 3d8+9 ) piercing damage.
Mutation Beams (Recharge 4–6). The sentinel attacks up to three separate creatures within 120 feet (that it is not directly facing). Each creature targeted must make a DC 16 Dexterity saving throw, taking 55 ( 10d10 ) poison damage (as radiation) on a failed save, or half as much damage on a successful one. Living creatures must also succeed on a DC 15 Constitution saving throw or gain a harmful mutation that fully develops over the course of 1d6 rounds. A target can gain only one harmful mutation per encounter with a zulerin sentinel. The mutation troubles the target for one day and then fades.


 


Appalling and alien, the burrowing biomechanical thing known as a zulerin sentinel pokes its head above ground in certain ruins of the prior worlds, or in locations that are essentially one giant machine (such as the Grave of the Machines). It is at least 20 feet long, with lumpy metallic skin, several clusters of tentacle-like arms, and two massive eyes that give off a brilliant light.   Gazing Meditation: Once it emerges from the ground or the larger machine it infests, the sentinel stares in one direction, locking its gaze on a particular machine, ruin feature, or precious component for hours, days, or even weeks at a time, as if in contemplation. It breaks eye contact only if it attacks another creature, or when its strange meditation ends and it departs.   Directional Threat or Reasonable Entity: If approached from almost any direction, a zulerin sentinel is a dangerous threat. However, if approached from the front (the direction of its gaze), it remains peaceful and open to interaction unless attacked. These creatures speak a variety of languages with a mechanical voice and, if approached straight on, will engage with characters. A zulerin sentinel may provide an interesting piece of information, but only if the PCs bring it salvage from the machine, ruin, or feature on which it has locked eyes. For reasons it won’t elaborate, it can’t move any closer.
