Due to an ancient and horrible truth your ancestors discovered in the past, your long-broken mind is afflicted by an indefinite madness. Either create a fitting quirk yourself, or choose one from the list below. If this madness is cured (such as by a greater restoration spell), you will likely develop a new form of madness within one year. Some kua-toa may remain sane for far longer though, so long as they don't experience a stressful event, such as the death of a family member of close friend.

Indefinite Madness

Choose a Flaw (lasts until cured)

• Being drunk keeps me sane.
• I keep whatever I can find.
• I try to become more like someone else I know--- adopting their style of dress, mannerisms, and name.
• I must bend the truth, exaggerate, or outright lie to be interesting to other people.
• Achieving my goal is the only thing of interest to me. I'll ignore everything else to pursue it.
• I find it hard to care about anything that goes on around me.
• I don't like the way people judge me all the time.
• I am the smartest, wisest, strongest, fastest, and most beautiful person I know.
• I am convinced powerful people are hunting me, and their agents are everywhere I go. I'm sure they're watching me all the time.
• There's only one person I can trust, and only I can see this special friend.
• I can't take anything seriously. The more serious a situation, the funnier I find it.
• I've discovered that I really like killing people.

You have proficiency with nets, spears, and shields.

You have proficiency with a musical instrument of your choice.

You have the uncanny ability to peer beyond the ethereal veil and see creatures hiding beyond the bounds of your reality. You learn the see-invisibility spell, and may cast it once per long rest without using a spell slot. You may also choose to expend a spell slot of 2nd-level or higher to cast this spell additional times.

Your naturally wet and slimy skin means that it is very hard to hold you down or restrain you. You have advantage on ability checks you make to escape a grapple and creatures have disadvantage on ability checks to grapple you.

At 5th level, you gain the ability to channel your maddening belief to manifest a divine entity.

When an ally you can see is reduced to 0 hit points or dies, you can use your reaction to roll on the following table (1d20) to summon a manifestation of divine power.

You may use this feature a number of times equal to your proficiency bonus, regaining all expended uses after a long rest. Once a roll on this table results in the manifestation of a Godling, you may no longer summon any more Godlings until you complete a long rest. All rolls on this table after summoning a Godling result in the following:

• Odd. Momentary Mind-Shatter
• Even. Spark of the Divine

Divine Manifestation

Roll a d20 and consult the table below to determine the effects.

• (1-5) Spark of the Divine. You gain 1d6 temporary hit points.
• (6-10) Momentary Mind-Shatter. One enemy you can see within 30 feet of you must make a Wisdom saving throw with a DC of 8 + your Constitution modifier + your proficiency bonus or have disadvantage on their next attack roll.
• (11-15) Lesser Godling. You create a lesser godling. The godling appears in an unoccupied space within 30 feet of you. Roll on the short-term madness table and gain one of its effects for one minute. After one minute, or once your madness is cured, the godling disappears.
• (16-19) Standard Godling. You create a godling. The godling appears in an unoccupied space within 30 feet of you. Roll on the short-term madness table and gain one of its effects for one minute. After one minute, or once your madness is cured, the godling disappears.
• (20) Greater Godling. You create a greater godling. The godling appears in an unoccupied space within 30 feet of you. Roll on the short-term madness table and gain one of its effects for one minute. After one minute, or once your madness is cured, the godling disappears.

Short-Term Madness

Roll a d6 and consult the table below to determine the effects.

• (1) You experience an overpowering urge to eat something strange such as dirt, slime, or moss. At the start of your turn, you must succeed on a Wisdom saving throw with a DC equal to 8 + your Constitution modifier + your proficiency bonus or use your action and movement to perform attempt to consume something within your immediate area.
• (2) You experience vivid hallucinations and have disadvantage on all ability checks.
• (3) You believe the nearest creature is a large and terrifying monster, and become frightened of it.
• (4) You believe your body is slowly freezing over. You feel extremely cold, and your movement speed is reduced by 10 feet.
• (5) You hear voices in your mind that aren't your own. You must follow out any command given to you that isn't obviously self-destructive.
• (6) You are convinced that all other people in the world have disappeared. You feel extremely lonely and melancholic, and have disadvantage on saving throws against being frightened or charmed.

Thanks to your Underdark ancestry, you have superior vision in dark and dim conditions. You can see in dim light within 60 feet of you as if it were bright light, and in darkness as if it were dim light. You can’t discern color in darkness, only shades of gray.

You can speak, read, and write Common and Undercommon.
