Mechanics
After taking damage, you will receive a demonic guardian with a chance equal to the percentage of the damage to your maximum health. Additionally, attacks that take 50% of your health at once or that leave you with less than 20% of your health will always summon a demonic guardian.
After receiving a guardian you will not receive another one for another (1+mutlevel) to (20+mutlevel) turns. The guardians always spawn friendly and won't be angered even if you attack them. Also, you can shoot ranged weapons and cast spells through your guardians without harming them. Even explosions like Fire Storm won't hurt demonic allies.
The strength of the demonic guardian is based on both the mutation level and your experience level:
Tier = mutlevel + ((XL - 9) / 9)
| Tier | Demons |
| 1 | 5  quasit, 5  white imp, 5  ufetubus, 5  iron imp, or 5  shadow imp
|
| 2 | 4  orange demon, 4  ice devil, 4  rust devil, or 4  hellwing
|
| 3 | 3  soul eater, 3  smoke demon, 3  sixfirhy, or 3  sun demon
|
| 4 | 2  balrug, 2  reaper, 2  lorocyproca, 2  cacodemon, or Script error  hell beast
|
| 5 | 1  Executioner, 1  Hell sentinel, or 1  Brimstone fiend

History
- Prior to 0.28, Okawaru did not suppress this mutation, as it did not forbid all allies.
- Prior to 0.27, guardians were summoned based on current tension rather than after being damaged. Also, the player couldn't shoot projectiles and cast spells through them.
- Prior to 0.14, this mutation was suppressed while worshiping Okawaru, as allowing an ally to die caused you to lose piety.
