Known Unlocks, Progidies, and other Special Effects:
Progidies:
- (Hydra Progidy) 50 Willpower and 1 Prodigy Point and finding a very rare dialog option in the Clasp menu: Hat Trick - Allows the Hydra to clasp Necklaces and Headgear.
- (Drakeling Progidy) Inspecting or Picking up a Crown item (excluding crown of burning pain) while having 3 Drakelings (at least one with its "Ultimate" trait): Legacy: Crowns can be clasped normally, and at least one drakeling gets a special personality (possibly more effects or drakelings. I don't know)
- (Ritch Progidy) 50 Cunning and 1 Progidy Point and using the Killing Blade effect on a Bow (Plus special step listed at end of the Prodigies list): Death from Above - Allows you to craft bow Impermanence Weapons (Requires one metal item, one belt, one piece of jewelry, and a bow) using Death from Above and unlocks shoot talent.
----- Special Step for Ritch Prodigy: First attempt- Choices as such: Bowstring (Bow), (I don't know perfectly for this step. I used Improvise and a helmet), Jewelry, and a belt.
Unlocks:
- Winning the Game as an Avatar: Therian- Class for non-summons that has hydra, drakeling, and mantis skills.
- Corrupting the Sandworm Queen's Heart and using it: Unlock the "Start as Blighted Form" option for Avatars (under Customize tab)(Only way to get original drakelings blighted).
AND causes the current character to hit blight threshold (If they are blighted already, they get a bonus to blight skills (I don't remember by how much)).
- Start an Avatar Game: rexorcorum graphics under Customize tab.
Consume And Other effects:
- Corrupted Heart of The Sandworm Queen: Causes the current character to hit blight threshold (If they are blighted already, they get a bonus to blight skills (I don't remember by how much)).
- Chromatic Harness: ?
- Storm Fury: Gives you a Proud, Loving, Male "Storm Drake"-themed Drakeling whose preferred NC is "Rabbit's Foot" and "Elusiveness" (has VERY high Defense and Trap Evasion).
- Consuming Heart of The Sandworm Queen (Drakeling): Next Drakeling is Proud, Loving, Female Drakeling who starts with TL10 Growing Bones, TL5 Swallow, TL4 Quake, and TL2 Sand Breath. Also has 50/100 knowledge, some special text, and prefers to learn Savage Strength and Nature Hardened.
- Using Heart of The Sandworm Queen (Drakeling, possibly others): Gives Burrowing Beast generic tree (Locked).
- Tooth of the Mouth: Gives all Monstrosities a Physical Power boost of 10
- Fiery Choker: "Monstrosity: Dragon" (I don't know exactly what that is yet). The Fiery Choker is a one fourth drop from Fyrk, the Faeros guard at Charred Scar (Portal from Var'Eyal in Eruan), so this is an extremely rare find.
- Wyrmbreath (Drakeling): Next Drakeling is Kanros (Special Dialogue) Extra Skills: Fire Breath 2, Devouring Flame 5, Bellowing Roar 4. Also, has Aspiration (Anti-Death) 3, and feels divided towards you. May have bonus stats, I can't tell.

- Primal Infusion: Gain 5 Wild Power.
- Eye of the Wyrm (Drakeling): ...? It is labeled and has an inspect message, but no effects I can see.
- Eye of the Wyrm (Hydra): When "Clasped" by a Drool head, it gives Hydra an additional head, as well as TL2 of "Venomous Breath".
- Blood of Life (Consumed and Gluttonied): Instant revival upon next death.
- Swordbreaker (Ritch): When used as an Impermanence Weapon, grants +.1 to Metal Rending and +5 to Swordbreaker (possible minor glitches (I suddenly seem to have 7 out of 5 ranks in Swordbreaker)).
