Death slaad

Death slaadi were very powerful evil slaad shapechangers and spellcasters.

Description
Death slaadi emerged as the result of a gray slaad having devoured the corpse of a dead green slaad. As their previous form, they could wield greatswords and imbue them with their own magic.

The death slaadi were infused with energy from the Negative Energy plane, which made them sadistic and cruel creatures. They commanded armies of lesser red and blue slaadi to invade other planes and used the survivors as hosts to spawn new slaadi.
