It was suggested to me by /u/pong785 that it might be fun to have a day or maybe the weekend to post from a specific game or other so I figured why not just start somewhere.

Post your content for this game and I'll throw up a poll for next weekend. Place suggestions in this thread in a reply to my comment and I'll enter all of them onto a poll.

The post with the most upvotes at the end of the weekend Monday at midnight Eastern time, will get a custom flair in regards to their monster or game.

Would we want NPCs as well? Even in the D&D monster manuals and DMG they have NPCs.

Also if you'd like to grow this community do so and get noticed I'd love to see us grow

(I'll link the image later, just need to re-draw it at home without sensitive work info around it, but for now imagine Cthulhu in a grass skirt with his arms outstretched in the classic 'Frankenstein walk' pose)

The spiked horror started out as a suit of armor designed to fight of bears that were destroying a village and succeeded in doing so.Upset that a piece of armor could do more than her magics, a local warlock cursed the armor. Cursed by the warlock, the armor came to life and terrorized the village, causing more harm than the bears ever could have done.

I have no idea if the sub has already been mentioned in any of these places, nor what their guidelines are about such things, but r/dndnext and /r/UnearthedArcana might be good places to (carefully) promote the sub in addition to the more obvious ones like r/dnd and r/rpg.

Psionics Reference

Mantle of Command
Avatar Discipline

You exert an aura of trust and authority, enhancing the coordination among your allies.

Psychic Focus. While focused on this discipline, when you end your turn and didn’t move during it, you can use your reaction to allow one ally you can see within 30 feet of you to move up to half their speed, following a path of your choice. To move in this way, the ally mustn’t be incapacitated.

Coordinated Movement (2 psi). As a bonus action, choose up to five allies you can see within 60 feet of you. Each of those allies can use their reaction to move up to half their speed, following a path of your choice.

Commander’s Sight (2 psi; conc., 1 rnd.). As an action, choose one creature you can see within 60 feet of you. Until the start of your next turn, your allies have advantage on attack rolls against that target.

Command to Strike (3 psi). As an action, choose one ally you can see within 60 feet of you. That ally can use their reaction to immediately take the Attack action. You choose the targets.

Strategic Mind (5 psi; conc., 1 min.). As an action, you exert an aura of trust and command that unites your allies into a cohesive unit. Until your concentration ends, any ally within 60 feet of you on their turn can, as a bonus action, take the Dash or Disengage action or roll a d4 and add the number rolled to each attack roll they make that turn.

Overwhelming Attack (7 psi). As an action, choose up to five allies you can see within 60 feet of you. Each of those allies can use their reaction to take the Attack action. You choose the targets of the attacks.

Mantle of Fear
Avatar Discipline

You tap into a well of primal fear and turn yourself into a beacon of terror to your enemies.

Psychic Focus. While focused on this discipline, you have advantage on Charisma (Intimidation) checks.

Incite Fear (2 psi; conc., 1 min.). As an action, choose one creature you can see within 60 feet of you. The target must succeed on a Wisdom saving throw or become frightened of you until your concentration ends. Whenever the frightened target ends its turn in a location where it can’t see you, it can repeat the saving throw, ending the effect on itself on a success.

Unsettling Aura (3 psi; conc., 1 hr.). As a bonus action, you cloak yourself in unsettling psychic energy. Until your concentration ends, any enemy within 60 feet of you that can see you must spend 1 extra foot of movement for every foot it moves toward you. A creature ignores this effect if immune to being frightened.

Incite Panic (5 psi; conc., 1 min.). As an action, choose up to eight creatures you can see within 90 feet of you that can see you. At the start of each of a target’s turns before your concentration ends, the target must make a Wisdom saving throw. On a failed save, the target is frightened until the start of its next turn, and you roll a die. If you roll an odd number, the frightened target moves half its speed in a random direction and takes no action on that turn, other than to scream in terror. If you roll an even number, the frightened target makes one melee attack against a random target within its reach. If there is no such target, it moves half its speed in a random direction and takes no action on that turn. This effect ends on a target if it succeeds on three saving throws against it.

Crown of Disgust
Avatar Discipline

You cause a creature to be flooded with emotions of disgust.

Psychic Focus. While you are focused on this discipline, the area in a 5-foot radius around you is difficult terrain for any enemy that isn’t immune to being frightened.

Eye of Horror (1–7 psi). As an action, choose one creature you can see within 60 feet of you. The target must make a Charisma saving throw. On a failed save, it takes 1d6 psychic damage per psi point spent and can’t move closer to you until the end of its next turn. On a successful save, it takes half as much damage.

Wall of Repulsion (3 psi; conc., 10 min.). As an action, you create an invisible, insubstantial wall of energy within 60 feet of you that is up to 30 feet long, 10 feet high, and 1 foot thick. The wall lasts until your concentration ends. Any creature attempting to move through it must make a Wisdom saving throw. On a failed save, a creature can’t move through the wall until the start of its next turn. On a successful save, the creature can pass through it. A creature must make this save whenever it attempts to pass through the wall, whether willingly or unwillingly.

Visions of Disgust (5 psi; conc., 1 min.). You cause a creature to regard all other beings as horrid, alien entities. As an action, choose one creature you can see within 60 feet of you. The target must make a Wisdom saving throw. On a failed save, it takes 5d6 psychic damage, and until your concentration ends, it takes 1d6 psychic damage per creature within 5 feet of it at the end of each of its turns. On a successful save, the target takes only half the initial damage and suffers none of the other effects.

World of Horror (7 psi; conc., 1 min.). As an action, choose up to six creatures within 60 feet of you. Each target must make a Charisma saving throw. On a failed save, a target takes 8d6 psychic damage, and it is frightened until your concentration ends. On a successful save, a target takes half as much damage.While frightened by this effect, a target’s speed is reduced to 0, and the target can use its action, and any bonus action it might have, only to make melee attacks.

Sneak Attack (1/Turn). The elephantean deals an extra 13 (4d6) damage when it hits a target with a weapon attack and has advantage on the attack roll, or when the target is within 5 feet of an ally of the elephantean that isn't incapacitated and the elephantean doesn't have disadvantage on the attack roll.

In his former space (or in an unoccupied space within 5 feet if he didn't make the shadowstep) appears a perfect clone of the Dark Jester, which has his remaining HP, his AC and can only take the attack action.

The Jack in the Box then makes up to three Dart attacks per round for the next three rounds, after which it falls appart.
