D20 Chaos One-Shots are a chance to try out the best characters against ridiculous odds. Every month the gauntlet is laid down to players to make a Level 20 build to group up and take on epic trials and god-like evil creatures. So are you up to the challenge?

Each themed event lasts over a week, with multiple sessions for different parties to face the challenge. In the weeks leading up to it, each player can sign up for a single upcoming session, but in the final days, players can opt to play in multiple sessions to fill in any gaps in the other parties.

At my tables, we run two different styles of table play to try and appease all players and what they like to experience for their fantasy enjoyment. The first style is Chaos Escape which focuses on the three pillars of dungeons and dragons, which we all have come to play from time to time. Those pillars are combat, role-playing, and exploration (challenges vary from low-combat puzzle/sneaky problems to high-combat arena clashes and Boss battles). The second style is Chaos Towers, based around one of the main pillars of dungeons and dragons: combat. (Attack or Defences style, but high-combat all the way).

Rules are changed each month to keep things interesting. Still, they expect level 20 with a range of powerful items (always wanted to try that particular Legendary?). Create your character sheet in D&D Beyond using the campaign link supplied in the discord Rules channel.

Tables	Injury Effect
1	Lose an Eye. You have a disadvantage on Wisdom (Perception) checks that rely on sight and ranged attack rolls. Magic such as the regenerate spell can restore the lost eye. You’re blinded if you have no eyes left after sustaining this injury.
2	Lose an Arm or a Hand. You can no longer hold anything with two hands and only a single object at a time. Magic such as the regenerate spell can restore the lost appendage.
3	Lose a Foot or Leg. Your speed on foot is halved, and you must use a cane or crutch to move unless you have a peg leg or other prosthesis. You fall prone after using the Dash action. You have a disadvantage on Dexterity checks made to balance. Magic such as the regenerate spell can restore the lost appendage.
4	Limp. Your speed on foot is reduced by 5 feet. You must make a DC 15 Dexterity saving throw after using the Dash action. If you fail the save, you fall prone. Magical healing removes the limp.
5-7	Internal Injury. Whenever you attempt an action in combat, you must make a DC 15 Constitution saving throw. On a failed save, you lose your action and can’t use reactions until the start of your next turn. The injury heals if you receive magical healing or spend ten days doing nothing but resting.
8-10	Broken Ribs. This has the same effect as Internal Injury above, except that the save DC is 13.
11-13	Horrible Scar. You are disfigured to the extent that the wound can’t be easily concealed. You have a disadvantage on Charisma (Persuasion) checks and an advantage on Charisma (Intimidation) checks. Magical healing of 6th level or higher, such as the heal spell and regenerate spell, removes the scar.
14-16	Festering Wound. Your hit point maximum is reduced by 1 every 24 hours the wound persists. If your hit points maximum drops to 0, you die. The wound heals if you receive magical healing. Alternatively, someone can tend to the wound and make a DC 15 Wisdom (Medicine) check every 24 hours. After ten successes, the wound heals.
17-20	Minor Scar. The scar doesn’t have any adverse effects. Magical healing of 6th level or higher, such as the heal spell and regenerate spell, removes the scar.

• Cannot attune to or benefit from more than one magic item of the same name (+1/+2 count as the same)
• Any Item attuned to a creature under your control (Familiars, Companions, etc.) counts against your character’s standard attuned items limit.

Homebrew

• Each month I create and provide a wide variety of homebrew content to add to a player’s epic fantasy experience. This content is approved for use during the event. If you want to see a list of the content available, click the link below.

House Rules

Please be mindful of other players and don’t use strategies that will significantly limit them being able to participate or having fun. To keep the game running as quickly and smoothly as possible, the following extra rules apply to our level 20 games:

• Drinking a Healing Potion can be either an Action or a Bonus Action. Healing Potions do not require the player to roll and instead recover for the max output of the rarity of the potion.
• Creatures who are immune to the Exhaustion Condition. No longer will receive this immunity.
• Players who are reduced to 0 HP will receive a maximum of 1 level of exhaustion and must roll from the Lingering Injury Table.
• Players may have a maximum of 1 Bonus token under their control on the board.
• Players can’t use Mythic or Legendary Actions from a creature’s stat block (Legendary Resistances are ok)
• Magic items are permanently absorbed into a Shape changed or Wildshaped form unless the new form is the same size class and has the same body part (e.g., hand/head) as your original form.
