QUICK REFERENCE
📍 HABITAT
- Forgotten dungeons or ruins of magically advanced civilizations
- Wizard towers and magical academies
- Ancient vaults or other noteworthy locations to protect for all eternity
🎭 BEHAVIOR
- Silent and relentless guardian, following programmed instructions, never retreats
- Adapts its body to attackers and environment, making repeated strikes less effective
- Often remains motionless until intruders approach, only acting when commanded or certain situations trigger it
🧠 INFORMATION (Intelligence Check)
- DC 10 History: Recognized as a magical construct powered by unstable geomancy
- DC 15 Arcana: Known for its malleable body that adapts to attacks and other situations
- DC 20 Arcana: Known for their rigid end, trapping foes in their stiffening body
⚔ COMBAT
- Prefers to stay outside melee range, hovering outside of harm or pushing creatures away from it, to continuously retrigger its Sentinel Attack reaction when they come back into melee range
- Changes into melee range when it becomes bloodied, to make the best of its Whirl attack and not to miss the opportunity to have a target for its Petrifying End upon death
💎 LOOT IDEAS
- Intact body parts to potentially rebuild or repair one of them
- Crystalized residual gravitational energy (usable to empower spells dealing force damage or spells that push or pull)
