Intro
The Illithid parasite is more than a curse—it is a tool of power, a gateway to something greater. Illithid Dominion allows you to take control of your transformation, bending the tadpole’s potential to your will.

No longer just a passive passenger, you now have the means to equip, consume, and harvest the power of the Mind Flayers, shaping your evolution as you see fit.

🔹 Equip Symbiotic Tadpoles of Potential – Regular, Astral, and Supreme tadpoles can now be worn as items, granting unique passive enhancements to your Illithid abilities.

🔹 Consume Experienced Tadpoles – Special parasites, harvested from certain True Soul foes, can modify your existing Illithid powers in unique ways.

🔹 Harvest Interesting Potential – Implant a parasite in incapacitated enemies, kill them, and extract the tadpole to claim a piece of their power. These stolen abilities generally focus on psychicforce, control, and raw mental dominance.

Will you wield the powers bestowed upon you to forge your own fate? 
Will you embrace the Dominion and reshape your mind into the ultimate weapon?


Note: Native French translation included / traduction française intégrée.
