Dungeon Core

You and a few other unfortunates have found yourself at the mouth of The Dungeon. It is blighting the land and causing the dead to rise, which is of course an issue, but more pressingly, you cannot leave while the Dungeon remains alive. Yes, alive. You must descend into the Dungeon, seize its Core, and expose it to the light of day to break the curse this blasted edifice has on you and the land both.

The Basics

If there’s a chance your character can fail at something, roll 1d20. Results of 11 or above indicate success. If your character has a relevant skill, add your proficiency bonus. If there are beneficial circumstances outside of your character’s personal skill, you can get advantage. If there are detrimental effects outside of your character’s skill, you might get disadvantage.

Advantage / Disadvantage

If the circumstances are in your favor, roll 1d6 and add the result to the roll. If the circumstances are not in your favor, roll 1d6 and subtract the result.

Advantage and disadvantage cancel each other out. Additionally, some other effects may increase or decrease the advantage or disadvantage applied.

Making a Character

Choose a a class, a perk, and three skills.

You apply your proficiency bonus to any skills you possess. Your proficiency bonus is equal to your level +2.

A newly created character is 1st level.

Classes

There are three classes: Warrior, Rogue, and Mage.
Warriors are those folks who dedicate their life to combat and bloodshed. Rogues live by their wits. Mages know deep secrets and spend their lives in pursuit of magic.

Warrior

Warriors can use any weapon, any armor, and shields. They apply their proficiency bonus to their attack rolls and damage rolls. They have d10 hit dice, and have 1d10+5 hit points. At 1st level, they choose one of the following:

  • Martial Artist: Your unarmed strikes count as light weapons. You have 3 focus. If you hit with an attack, you can spend a point of focus to immediately make an unarmed attack. You recover all focus after a short rest.
  • Fighter: Your weapon damage dice increases by one die size. Your critical strike range increases by one.
  • Outlander: Your hit dice increases by one die size, and you gain three hit points at first level.

Rogue

Rogues can use light weapons and light armor, but not shields. Rogues have a d8 hit die and have 1d8+4 hit points.

At first level, a Rogue gains two additional skills, then they choose one of the following:

  • Assassin: When you strike an enemy that is unaware of you, you gain 1d6 advantage on the weapon strike. If the strike lands, you deal 1d6 bonus damage.
  • Adept: You gain two 0th level spells that you can cast at-will. You gain a 1st level spell. You have spell points equal to your level.
  • Acrobat: You have 3 focus. You can spend a point of focus during your turn to move half your speed in any direction. You regain your focus after a short rest.

Mage

Mages can use light weapons, but cannot wear armor or use shields. They add their proficiency bonus to their spell-casting rolls. Mages have d6 hit dice and have 1d6+3 hit points.

Mages have spell points equal to twice their level, and, at first level, know three spells.

At 1st level, a Mage chooses one of the following:

  • Warcaster: You may wear any armor, and use shields.
  • Wizard: You have a spellbook.
  • Acolyte: You have an additional skill, and your hit die increases to d8.

If you have a spellbook, you have access to more spells than usual, as long as you have your spellbook on hand. A spellbook can contain up to ten levels of spells inside of it. When you come across another wizard’s spellbook, you may be able to transcribe it.

Perks

Choose one of these at character creation.

  • Darkvision: You can see in shadows as though it was fully lit. You cannot see in total darkness.
  • Iron Stomach: Immune to disease and resistant to poison damage.
  • Deadly: When you roll a natural 20 on an attack roll, increase the damage die by 1 step.
  • Natural Concealment: Disadvantage to those trying to notice you, as long as you are totally still and have made a token effort to hide.
  • Toughness: You gain 2 bonus hit points every level.
  • Tinker: You can produce small, simple mechanical clockwork items out of scrap and junk. These clockwork gizmos can play music, clatter, bounce around, or similar nominally harmless effects.
  • Massive: You are considered Large. You increase your hit die by one step, and you can use larger weapons.
  • Diminutive: You are considered Small. You can dart between the legs of larger creatures, and they can provide cover for you. You eat half as much.
  • Natural Wizardry: You know a 0th level spell that you can cast at will. You know a 1st level spell. You gain 1 spell point.
  • Avian: You have hollow bones, and can jump twice as far. You take half damage from falling.
  • Amphibious: You can hold your breath for ten minutes without issue, and have a swim speed equal to half your walking speed.

A skill is any set of experiences, training, or aptitudes that shape who a character is and what they do. The skills listed below are suggestions; feel free to use your own.

Equipment

Medium sized weaponry deals 1d6 damage. Small weapons deal 1d4 damage. Large weapons deal 1d10 damage.

Medium-sized creatures can wield a medium weapon in their main hand, or a large weapon in two hands. A weapon at least one size smaller can be wielded in an off-hand.

Swords deal critical hits on a roll of 19 or 20.

When Maces deal a critical hit, the target must save or be stunned. Difficulty is 10 + the damage dealt.

When Axes deal critical hits, increase the damage die by two sizes.

Standard defense for an alert human-sized combatant with no armor or shields is 10.

Light armor grants +3 defense.

Heavy armor grants +6 defense, but its wearer suffers 1d6 disadvantage on checks related to sneaking, swimming, or climbing.

When Shields are wielded, they provide +2 defense.

Fighting

Sometimes, you can’t avoid violence.

When you attack another being with your weaponry, roll 1d20. If your result is higher than their defense, you inflict damage.

When you inflict damage, roll the weapon’s damage die. Your opponent will subtract the result from their hit points. If they survive, they may attempt to return the favor.

Damage reduction, if present, reduces the damage from each attack by the listed amount.

Getting Hurt

When you run out of hit points, you are incapacitated. An incapacitated character cannot move, fight, or cast spells. An incapacitated character recovers if tended to by another character, a process which takes several minutes.

A character who becomes incapacitated also gains an injury.

Resting

A short rest is a quick breather, no less than half an hour without strenuous activity. When you complete a short rest, you can ‘spend’ a hit die to recover 1 hit die worth of hit points (ex. if your hit die is d10, you recover 1d10 hit points.) You may also recover focus, or any other resources that return on a short rest.

A long rest is a full night’s sleep, a good meal, and a warm fire. After a long rest, you recover hit points equal to your maximum hit points, and you recover all of your hit dice. Additionally, you mark one tick towards recovering from an injury.

Sleeping Rough

If you are missing one of the requirements for a long rest, you recover a number of hit points equal to half of your hit points, and half of your hit dice. If you are missing two out of three, you gain only the benefit of a short rest.

Environment

Difficult terrain is broken, cracked, thorny, slippery, or otherwise hard to traverse. You move half as fast over difficult terrain.

Characters can swim at about 1/4 their normal walking speed. They may need to make a check when in a rush, or if the water is choppy or fast-moving.

Characters can climb at about 1/4 their normal walking speed. They may need to make a check if the surface is slippery, they are carrying a lot, they are in a rush, or if the surface is especially challenging.

Falling typically deals 1d6 damage per ten feet dropped. Characters can save (difficulty 10 + damage) to try and roll at the end of the drop, to avoid getting hurt.

Gaining Experience

A character

Leveling Up

When you become second level, you gain additional hit points equal to your hit die size. (ex. if your hit die size is d6, you gain 1d6 hit points)

When you hit third level, you may choose a Talent Perk. You may instead choose to gain another 1st level Perk from your class instead, if you wish.

When you become fourth level, you gain additional hit points equal to your hit die size.

When you become sixth level, you gain a Capstone Perk. You may instead choose to gain a Talent Perk instead, if you wish.

Talent Perks

Weapon Mastery: When you wield a weapon, increase its damage die by one step. Additionally, you gain +1 critical strike range.

Brutality: You gain 2 focus. When you deal a critical strike with a weapon, you may spend one focus to force your target to suffer the critical effect twice, then gain hit points equal to half your hit dice.

Guardian: You have 1 Damage Reduction and +1 Defense. Whenever an ally is standing next to you, you may put yourself in harm’s way to protect them, taking any damage meant for them.

Berserker: Whenever you take damage, gain that many points of Rage. For every 3 points of Rage you have, you gain +1 to your attack and damage rolls. For every 6 points of Rage you have, you gain +1 Damage Reduction. Rage quickly dissipates after the threat has passed.

Aspect of Stone: You gain 2 focus. Whenever you take damage, you may spend a point of focus to

Energy: You gain 2 focus.When you choose to use a point of focus, you gain +1 to attack rolls and +1 defense until the end of that turn.

Hands without Shadow: When you deal damage to an enemy with an unarmed attack, you gain 1 focus. When you make an unarmed attack against an enemy, you may instead make two unarmed attacks against that enemy.

Peace and Calm: When you spend a point of focus, you may shift immediately before or after that action a distance of up to 5′.

Concealment: When you

Capstone Perks

Spells

To cast a spell, first spend spell points equal to the level of the spell. Then, roll a Spellcasting test, difficulty 10 + twice the spell’s level.

Many spells require their targets to ‘save’ or suffer additional effects. The difficulty is always 10 + the caster’s level + the spell level.

Spell points recover after a long rest.
