# [Blue Slaad](3-Mechanics\CLI\bestiary\aberration/blue-slaad-xmm.md)
*Source: Monster Manual (2024) p. 285*
Almost as numerous as red slaadi, blue slaadi are muscular brutes with vicious blades extending from the backs of their claws. These claws carry a magical curse called chaos phage, which can transform victims into red or green slaadi. Blue slaadi accompany red slaadi and behave similarly. They innately know the signs of chaos phage and avoid slaying creatures that carry it or other slaad curses.
## Slaadi
*Chaos-Spawned Hordes of Limbo*
- **Habitat.** Planar (Limbo)
- **Treasure.** Any
Unpredictable slaadi devour and multiply across the Ever-Changing Chaos of Limbo. These toad-like, extraplanar beings embody the endless potentiality of their home plane of existence. While slaadi aren't inherently evil, their impulses are wild and often destructive. Many are driven to propagate through supernatural processes. Unfortunately, these processes typically are fatal for other creatures.
Slaadi have no formal society. Rather, strong slaadi dominate weaker ones. Blue and red slaadi rampage across Limbo and spill into other worlds at the direction of green slaadi. More powerful slaadi have connections to the Spawning Stone, a source of chaotic magic from which the first slaadi originated. The Spawning Stone is hidden deep within Limbo, and legends tie its origins to the modron overlord Primus or the ruinous slaad lords, such as Ssendam, the golden amoeboid terror, and Ygorl, the winged skeleton. These slaad lords and others plot to spread slaadi across the multiverse.
> [!note] Slaad Control Gems
>
> A slaad born from the Spawning Stone has a magical control gem embedded in its head. If a creature claims the gem, the slaad has the [Charmed](3-Mechanics/CLI/rules/conditions.md#Charmed) condition and obeys the gem's bearer. The slaad ceases to be [Charmed](3-Mechanics/CLI/rules/conditions.md#Charmed) if it is harmed by the gem's bearer or the bearer's allies or if the gem is returned to the slaad. A [Greater Restoration](3-Mechanics/CLI/spells/greater-restoration-xphb.md) spell cast on a slaad destroys the gem, and the slaad ceases to be [Charmed](3-Mechanics/CLI/rules/conditions.md#Charmed).
>
> One can obtain a slaad's control gem using a [Wish](3-Mechanics/CLI/spells/wish-xphb.md) or [Imprisonment](3-Mechanics/CLI/spells/imprisonment-xphb.md) spell. If the slaad fails its saving throw against [Imprisonment](3-Mechanics/CLI/spells/imprisonment-xphb.md), the caster gains the gem, and the slaad isn't imprisoned. An [Incapacitated](3-Mechanics/CLI/rules/conditions.md#Incapacitated) slaad's control gem can be removed by spending 1 minute and succeeding on a DC 20 Wisdom ([Medicine](3-Mechanics/CLI/rules/skills.md#Medicine)) check. Failing this check deals 22 (`4d10`) Piercing damage to the slaad.
