House Rules

Rapid Quaffing
(Tal'Dorei Campaign Setting)

• You can drink a potion as a bonus action instead of an action.
• NPCs and enemies can also drink potions as a bonus action. 
• Administering a potion to another creature still requires an action. 

Spelldriver

(Tal'Dorei Campaign Setting)

• Starting at character level 8, you are no longer limited to only one non-cantrip spell per turn. However, should you cast two or more spells in a single turn, only one of them can be of 3rd level or higher. 

Dual-Focused

(Tal'Dorei Campaign Setting)

• If you attempt to cast a spell that requires concentration while already concentrating on an existing spell, you can maintain concentration on both spells simultaneously.
• If you take damage during this time, you must make a concentration check for each spell individually. 
• At the end of each turn where you have two spells you are concentrating on, you must make a Constitution saving throw (DC 8 + both spells' levels combined). On a success, you maintain concentration while on a failure you lose concentration. 

Death and Returning
(Xanathar's Lost Notes to Everything Else)

• Three Strikes and You're Out
• Each time a creature is brought back to life via magic, a piece of their soul remains in the afterlife. 
• You may only return from death twice before your soul is permanently anchored in the afterlife. 
• A third death is the absolute final for any creature. After that a creature can't be brought back to life by any means short of a wish spell or miracle.
• The Soul is Fragile
• Outside of the body, a soul is fragile and can easily be destroyed. The process of bringing a person back to life is hard on the soul and there's a chance a returning soul could be destroyed in the process. 
• A caster must make a DC 15 ability check using their spellcasting ability modifier. 
• If the check fails, the DM should roll on the appropriate Fragile Soul table for the result.
