The Alchemical Catalyst

You weren't just a child of two worlds; you were a "specimen" in a controlled environment. Whether held by a Wizard's Circle, a Hag Coven, or a secret cult of the Outer Planes, your life was defined by the grind of experimentation

Ability Scores:

• Charisma (Main Attribute): Usually +2. This reflects the subject's innate supernatural presence, whether it manifests as angelic magnetism or demonic menace.
• Wisdom or Intelligence: Often +1. This represents the subject's heightened awareness (celestial) or cunning (demonic).
• Strength or Dexterity: Frequently +1 or +2. Depending on the demonic parentage, the subject may have superhuman physical power or unnatural, predator-like agility.
• Constitution: High scores (14+) are common in "test subject" lore to reflect the unnatural durability required to survive the fusion of two opposing cosmic forces.

Skill Proficiencies:

• Skill Proficiencies: Arcana (from identifying the spells cast on you) and Survival (from enduring the harsh conditions of your "cell").

Tool Proficiencies:

• Tool Proficiencies: Alchemist’s Supplies or Glassblower’s Tools (reflecting your familiarity with the lab equipment used to contain your energy).

Languages:

• Languages: One of your choice (Celestial or Abyssal/Infernal), plus one "Secret" language (like Undercommon or Deep Speech) whispered by other prisoners.

Suggested Characteristics

d6	Personality Trait
1	I have a physical "stress tic" (like humming or cracking my knuckles) that triggers when I sense strong magic.
2	I am obsessed with structural integrity; I find myself constantly looking for the weakest point in every room.
3	I don't understand the concept of "privacy"—my life was lived behind glass and under observation.
4	I equate physical pain with progress, as that was the only time my captors spoke to me.
5	I collect small "shards" (glass, pebbles, salt) as a way to feel like I have control over my own shattering nature.
6	I am incredibly suspicious of healers; I assume every "cure" comes with a hidden side effect.
