All Campaigns use

• Generalized Musical Instrument Proficiencies. Musical instrument proficiencies now represent training with a category of instruments rather than single, individual instrument.  Categories are determined by the primary manner in which the instrument is played, rather than what material it is made of or what components it involves, and are as follows:

• Bowed strings (e.g, violin, chello, hurdy-gurdy, húqin, yàzhēng, haegeum, lyra, igil, nyckelharpa, etc.)

• Fingered strings (e.g. lute, yarting harp, lyre, guqin, sitar, mandolin, guitar, etc.)

• Percussion (e.g. hand drum, tocken, wargong, tantan, bodhran, tabla, rattles, shakers, tambourine, jaw harp, idiophones in general)

• Wind (e.g., birdpipes (shalm), longhorn, shawm, thelarr, glaur, gloon, conch shell, flute, carnyx, didgeridoo, duduk, ney, bagpipes, etc.)

• Keyboard (e.g. zulkoon, water organ, accordion, etc.)

• Improvised (things not crafted for musical purpose but unconventional music can nonetheless be made with them. e.g., torches, weapons, …)
  
  

• Grappler’s Privilege. If a grappled creature would be moved out of the reach of a grapple or similar situation by a third party, effect, or event that would force the grappled target to make a contested strength, dexterity, or constitution ability check (or to make a strength, dexterity, or constitution saving throw), the grappling creature may make the ability check (or saving throw) on the grappled creature’s behalf.

  • • Additionally, a grappling creature may substitute their own armor class for any ability or spell that would move a grappled creature out of the reach of the grappling creature on a successful hit. On a successful hit against the grappler’s armor class, the grappled target is struck as normal by the ability or spell, and moved.

    • Abilities that allow a third party to trade places with a grappled (and/or restrained) target result in the third party becoming immediately grappled (and/or restrained) instead.

    • A grappling creature may not use their own intelligence, wisdom, or charisma ability check (nor intelligence, wisdom, or charisma saving throw), in this manner. Additionally, magical effects that teleport or transpose their grapple target function as normal.

    • Example 1: A wizard is being grappled by a vampire, and one of the wizard’s allies (a barbarian) wishes to use their own strength (athletics) check to grapple the wizard and pull them out of the vampire’s grasp. In this situation, the vampire may contest the barbarian’s grapple on the wizard’s behalf. If the vampire succeeds or ties the barbarian, the grapple attempt fails. If the barbarian succeeds, they grapple the wizard and can move them out of the vampire’s reach, breaking the grapple.

    • Example 2: A barbarian is being grappled by a vampire, and one of the barbarian’s allies (a wizard) wishes to use the Thunderwave spell to shove the barbarian out of the grapple. In this situation, the vampire may use their own constitution saving throw in lieu of the barbarian’s saving throw to resist the spell. If the vampire succeeds on this saving throw, the barbarian is treated by the spell as if they succeeded on the saving throw. If the vampire fails on the saving throw, the barbarian is subjected to the spell as if they failed on the saving throw, and may be moved out of the vampire’s reach, breaking the grapple.

    • Example 3: A barbarian is being grappled by a vampire, and one of the barbarian’s allies (a wizard) wishes to use the Vortex Warp spell to teleport the barbarian out of the vampire’s reach, breaking the grapple. The spell functions as normal (and the barbarian may choose to make a saving throw or choose to fail as per the spell description).
      
      

• Magical Psionics. In general, all abilities referred to as ‘psionic’/’psychic’ are also considered ‘magical’ for determining how they interact with other spells and effects. For example, a mind flayer’s Mind Blast ability is referred to in the text as ‘magical’, but this errata would rule it as magical even if the text did not.

  • • Magical Psionic Subclasses. All of the features of the following Psionic subclasses from Tasha’s Cauldron of Everything are now considered magical for the purposes of spells and abilities: Psi Warrior Fighter, Soulknife Rogue, and Aberrant Mind Sorcerer. These features are magical even if the text fails to specify whether they are or not, but they do not count as spells. This means they are subject to Antimagic Field, and a creature with advantage on saves versus magical effects would have advantage on saves against them, but they are not subject to dispel magic.

    • Magical Psionic Feats. Similarly, the Telepathic and Telekinetic Feats are also magical, and interact with other spells and abilities as appropriate.
      
      

• Unarmed Strikes. Count as simple melee weapons that have a value of 0 and have no weapon properties. 

Variant Rules that some Campaigns MAY use

• Choose to Fail Save. Any creature can choose to fail a Save even if the effect does not state that they can.  GM discretion still applies.
  
  

• Double Grapple Restrain. A second successful grapple check performed by a grappler on a creature they already have grappled restrains both the creature and the grappler.
  
  

• Grappling Weight. The weight of a grappled creature is taken into account when checking the carrying capacity of the creature doing the grappling. This weight is determined by checking the weight of the exact (or a similar) creature in the D20SRD here: https://www.d20srd.org/indexes/monsters.htm, and is subject to GM adjudication. The carrying capacity is only relevant in situations where a creature intends to move their target, and is measured against the different carrying capacity modifiers for lifting versus dragging a target, depending entirely on what the grappling creature wants to do. Depending on the circumstances, a GM may waive some or all of this additional weight to account for conditional modifiers, such as if a creature is buoyant in water, or in a zero-gravity environment.
  
  

• Help Requirements.

  • • Anyone can help anyone else with any ability check as long as A: both people could have individually passed the check with a high enough roll, and B: the check doesn't require both people to pass it individually to succeed (IE: Sneak, Acrobatics).

    • (Proficiency) You cannot provide the Help Action to a non-physical skill or tool check unless you have Proficiency in the skill or tool.  Alternatively, you may attempt to substitute your own skill or tool check as considered relevant by the GM, if you are successful, you provide the Help Action.
      
      

• Hold Action Dash. A creature holding an action to Dash may move up to their speed when their held action is triggered, instead of doubling their speed.
  
  

• Passive Skill Floor. The passive score (10+Skill Modifier) of a Skill in which you are Proficient is the minimum you can roll on an ability check using that skill.
  
  

• Shared Minion Initiative. All summoned creatures, mounts, and cohorts act on their controller's initiative in combat, either immediately before, or immediately afterward.
  
  

• Sorcery Point Conversion. Pact Magic spell slots cannot be used to gain Sorcery Points.
  
  

• Stacking Advantage/Disadvantage. When determining whether a d20 roll has advantage, subtract the number of disadvantage effects on that roll from the number of advantage effects on that roll.  If the roll's number of modifiers is still positive, make the roll with advantage rather than a flat roll (which it otherwise would be per rules as written).  If the roll's number of modifiers is still negative, make the roll with disadvantage instead.  If the roll's number of modifiers is neutral, then (and only then) make a flat roll.
  
  

• Unintended Surface Reroll. Die results are only valid if the die was rolled on a flat, intended surface, and the die falls flat.

Radiant Realm Magic/Invocation Errata used by all Campaigns

• Amulet of the Devout (TCoE).  The second sentence of the item description now includes the underlined addition: "While you wear the holy symbol, you gain a bonus to spell attack rolls and the saving throw DCs of your cleric and paladin spells."  This magic item's bonuses apply to only cleric and paladin spells, just like how the equivalent items for other classes apply to only that class's spells, regardless of abilities to ignore class attunement restrictions.
  
  

• Devil's Sight (PHB). This invocation also eliminates the need for darkvision to see clearly within its range.
  
  

• Immovable Object (EGtW). This spell only functions when cast upon an object that is either being carried or worn by a willing creature OR unattended or otherwise not being worn or carried by an unwilling creature.
  
  

• Silvery Barbs (SaCoC). This spell only applies after all instances of advantage/disadvantage are resolved and there's only one die to reroll.
