# [Chasme](Rules\Source\bestiary\fiend/chasme-xmm.md) *Source: Monster Manual (2024) p. 69* ## Chasme *Demon of Betrayal and Sycophancy* - **Habitat.** Planar (Abyss) - **Treasure.** [Relics](/Rules/Source/tables/random-magic-items-relics.md) Flying forth from the Abyss, chasmes resemble horse-size flies. They incapacitate foes by producing a mind-numbing droning, then use their proboscises to drain victims of life. In the Abyss, most chasmes obsequiously serve more powerful demons and search for captives to press into demonic hordes. ```statblock "name": "Chasme (XMM)" "size": "Large" "type": "fiend" "subtype": "demon" "alignment": "Chaotic Evil" "ac": !!int "15" "hp": !!int "78" "hit_dice": "12d10 + 12" "modifier": !!int "5" "stats": - !!int "15" - !!int "15" - !!int "12" - !!int "11" - !!int "14" - !!int "10" "speed": "20 ft., fly 60 ft."
