Mutate your Mutation Table!

Roll on this table each time you roll on your mutation table. For a more stable mutation table, roll on this table only when rolling a 1 on a d6 when you roll on your mutation table.

These results permanently modify your mutation table, I suggest to print your table to be able to write on it to make modifications.

("Entry" refer to the entry that was rolled on the mutation table.)

Mutations table’s Mutations (d20)
  1. The mutation become more common, the entry duplicate itself and replace a other random entry on your mutations table. 
  2. The entry merge with the previous or following entry, become a single entry, cumulating the effect of both entries. 
  3. Write a d3 variant effects subtable for the entry. Add a entry to the subtable if you reroll this result for the same entry. 
  4. The entry grow and evolve, augment it effect by one step. If something give a +1 it now give +2, etc… Cosmetic effects become more extreme, apparent and harder to hide. 
  5. The entry become more specialized. It effect become more detailed and precise, write down a extra detail into the entry. 
  6. The entry become purely cosmetic, entries that are already cosmetic become fashionable and grant a minor bonus to reaction rolls. People start wearing clothings that evoke the mutation effect. 
  7. The mutation mutation switch some details, traits or effects with a other random mutation.
  8. The effect become deadly, after each day the mutant must pass a saving throw or die. If the saving throw is successful, the mutation stabilize and the mutant gain a saving throw bonus. Mutations that are already deadly prevent the mutant from dying from their mutation and turn them into a undead. 
  9. The entry shrivel and disappear from the random table, attribute it’s table number to the previous or following entry. The mutant is the last to ever receive this mutation. If it was a PC grant them some XP and a reputation, if it was a creature grant them a additional HD. 
  10. The entry become a magic-user spell and escape into the nearest spell book or scroll. It become a level d4 spell, duration effect depend of the spell level (Level +d6 rounds, turns, hours, days). Each time the spell is cast, it have a chance on a d20 of being a permanent effect and also affecting the spell caster. The GM can now add this spell to NPCs spell books. Remove the entry from the mutation table and attribute it table number to the previous or following entry. 
  11. The entry become a unique monster afflicted with a extreme version of the mutation. This monster have d6+3 HD. It’s attacks are infectious and inflict the mutation on a failed save. Add the monster lair on your map and infect d6 neighboring creatures and NPCs. Remove the entry from the mutation table and attribute it table number to the previous or following entry. 
  12. The entry become a specie of creatures. These creatures have 1HD and are afflicted with the mutation. They reproduce quickly. Add them to your random encounter table. Remove the entry from the mutation table and attribute it table number to the previous or following entry. 
  13. The entry become a magical item that inflict the mutation’s effect. Roll a random magic item to determine it nature. The magical item afflict the mutation when it apply it magical effect. If a non consumable magic item was rolled, the item is unique. Remove the entry from the mutation table and attribute it table number to the previous or following entry. 
  14. The entry become a minor divinity. Each time this entry is rolled it grant itself as a first level cleric spell to the nearest cleric (duration: LV+d6 turns, range: touch). Place a cult in the nearest village or monster lair and add clerics of this mutation to your random encounter table. If you reroll this result for the same entry, the mutation divinity grow in power and influence. 
  15. The entry become sentient and link together all creatures afflicted with the same mutation into a hivemind. It have it own chaotic agenda and will discuss with it afflicted creatures like a intelligent weapon, sometime influencing them through mental suggestions (once after each rest, saving throw to resist). If you reroll this result for the same entry, the mutation grow in power and it’s suggestions are harder to resist. 
  16. The entry become a contagious disease, afflicted creatures spread the mutation with their bodily fluids (save to avoid being infected). If the entry is already contagious, the virus become airborne. Infected creatures roll a saving throw every d6 days to see if they are cured. Each time the mutation is rolled, it trigger a new wave of contagion in the local area, random NPCs have a chance on a d10 of being afflicted. If the same result is rolled for this entry, it become harder to save against the disease. 
  17. This entry now trigger a additional random mutation d20 hours later. If you reroll this effect for this entry, it trigger one more mutation. This may lead to a chain of mutations. 
  18. This entry now also regenerate the mutant: regrowing lost limbs, removing diseases, rerolling it maximum and current HP. The mutant also feel good about their new mutation, as if they feel beautiful and healthy. If the same result is rerolled for this entry, the regeneration grant a die reroll when rerolling the maximum HP. Mutant afflicted by this mutation are now considered “holy” by other mutants. 
  19. The entry apply it mutation and trigger a burst of mutation d20 hours later, inflicting a random mutation to anyone in a close area around the mutant. If the same result is rerolled for this entry, step up the area of effect. 
  20. This entry become less potent, granting a saving throw. People who pass the saving throw are cured of it effect after d6 days. A mutation vaccine can be created with their blood. Receiving the vaccine inflict the mutation, after d6 days make a saving throw to remove this mutation and a other mutation every d6 days. People who received the vaccine gain advantage or a bonus to resist new mutations. If you reroll this result for this entry, grant a bonus or advantage to the vaccine saving throw. Mutants must make a saving throw to avoid the temptation of eating people who received the vaccine, eating them grant the vaccine to the mutant.
