Death slaad

Death slaads were visually indistinguishable from gray slaads.

Personality
Despite still having all memories of their former green and gray slaad selves, the behavior of the death slaadi starkly contrasted their previous attitudes, specifically in regards to their interests. No longer concerned with increasing their magical powers, death slaadi were sadists focused on bringing death and pain to those around them, the most powerful of which undergoing rogue training in order to later become full-fledged assassins.

Abilities
As their previous form, they could wield greatswords and imbue them with their own magic.

Society
They commanded armies of lesser red and blue slaadi to invade other planes and used the survivors as hosts to spawn new slaadi.

Ecology
Death slaadi emerged as the result of a gray slaad having devoured the corpse of a dead death slaad. The death slaadi were infused with energy from the Negative Energy plane.
