Liminal Shattered House Rules

Training

Advancing in level after 4th level requires a measure of training.
This takes ten days of training for levels 5 - 10, twenty for levels 11 - 16, and thirty for levels 17+.
This training does not have to be done all at once, an in fact can be "stored up" until the character levels, allowing them to level up immediately.
Neither does this training have to be accomplished all at the same time, permitting the characters to accrue a few days of training here and there in preparation for their next level.
Characters can also discover training manuals, trade secrets and other lore that functions to grant a certain amount of training.

A character starts with 5 hero points at 1st level. Each time the character gains a level, he or she loses any unspent hero points and gains a new total equal to 5 + half the character’s level.
A player can spend a hero point whenever he or she makes an attack roll, an ability check, or a saving throw to make that check at advantage.
On a failed roll, the player may spend a hero point to re-roll.
In addition, whenever a character fails a death saving throw, the player can spend one hero point to turn the failure into a success.
Heroes gain Hero Points instead of Inspiration, although the normal methods of gaining Inspiration still apply - that is, significant roleplaying that cleaves to the hero's Ideals, Bonds and Flaws.

Healer's Kit: A character can’t spend any Hit Dice after finishing a short rest until someone expends one use of a healer’s kit to bandage and treat the character’s wounds.
Healing Surge: As an action, a character can use a healing surge and spend up to half his or her Hit Dice.
- For each Hit Die spent in this way, the player rolls the die and adds the character’s Constitution modifier.
- The character regains hit points equal to the total.
- The player can decide to spend an additional Hit Die after each roll.
Slow Natural Healing: At the end of a long rest, characters recover up to half of their Hit Dice.
- Additionally, at the end of a long rest, characters may spend as many Hit Dice as they like to heal their characters.
- Hit Dice may only be spent in a short rest through the use of a Healer's Kit (above).

Anytime one of the following occurs, check for Lingering Injury, using that chart in the DMG.
- When a character takes a critical hit.
- When a character drops to 0 hit points, but isn't killed outright.
Make a save based on the potential Lingering Injury; this is a Constitution save, DC 10 + the proficiency bonus of the attacker.

Adventurers that encounter threats they have no hope of overcoming, the DM may all for a Wisdom saving throw, at a DC he sets.
A character who fails the save becomes frightened for 1 minute.
The character can repeat the saving throw at the end of each of his or her turns, ending the effect on the character on a successful save.

Horror involves more than simple fright. It entails revulsion and anguish.
Often it arises when adventurers see something completely contrary to the common understanding of what can and should occur in the world, or upon the realization of a dreadful truth.
A character in such a situation must make an Intelligence saving throw to resist the horror, with a DC established by the DM.
On a failed save, a character gains a short-term or long- term form of madness, per the DMG.
