Description
Back in the time where arkans ruled the land, these cores were often used as generators for their tech. Absorbing souls, and converting them into energy enriched crystals. However, some of these obelisks still survive today, and without being monitored by Arkan scientists, they will cover the environment with these energy crystals, and even use them to revive the corpses of other formerly deceased crystals.
many Archeologists search for these crystal batteries, but not all know their dangerous potential.
Lair and Lair Actions
Because crystal obelisks are stationary, they can only ever be found where they were first constructed. This is usually as the power cell for a temple or city, owned by the now extinct arkans. Due to their soul devouring and crystal constructing tendencies, if left unmonitored they will end up covering entire areas in crystal.
Lair Actions
On initiative count 13 (losing initiative ties), the [monster name] takes a lair action to cause one of the following effects; the [monster name] can’t use the same effect two rounds in a row:
- Summon a crystal wall with the same diameter of that originating from the action.
- Summon an earth elemental
- Restrain one creature the obelisk can see, in crystals.
Regional Effects
The region containing an obelisk’s lair is crystallized , which creates one or more of the following effects:
- Slain creatures bodies are converted into crystals, that then control nearby Deceased creatures.
- Magenta crystals pierce the ground often
- Sparks occasionally fly around in the sky
If the Obelisk dies, these effects fade over the course of 1d4 days.
