Monster of the Month: Blade Demon

Each month, we’ll give you a new monster to use in your 5e game. This month, we give you the Blade Demon. You can download the description and stat block of the blade demon here.

Blade Demon

Blade demons are vicious, insectoid-like demons whose six limbs all end in razor sharp blades. Blade demons scuttle around on these scythe-like limbs, but when it comes time to fight, they are surprisingly good at balancing on their two back ‘legs’, allowing them to attack with four of their bladed ‘arms’ all at once.


There is an old dwarven expression: “If yer only tool be a hammer, then ye’ll be treatin’ everythin’ like a nail.” Well, a blade demon’s only tools are its bladed limbs, and so it treats everything as something to be sliced. People, animals, trees, and even other demons – the blade demon interacts with everyone and everything in the same way: trying to slash it to bits.

Swaths of Destruction.

Blade demons scuttle about like insects on their six scythe-like limbs. This movement leaves a trail of slashes and cuts wherever the blade demon goes; their blades are strong and sharp enough even to leave cut marks in stone. This makes blade demons very easy to track – Wisdom (Survival) checks made to track a blade demon have advantage. However, one would have to be mad or very, very desperate to want to track down a blade demon.
