Reverberation (Condition)

Reverberation

• Affected entity has a -1 penalty to Strength, Dexterity, and Constitution  Saving throws per remaining turn.

• When the entity has 5 or more turns of Reverberation, it takes 1d4⁠⁠Thunder damage and must succeed a DC 10  Constitution saving throw or fall  Prone. The condition is removed afterward.

• Creatures Immune to ⁠Thunder damage can't receive Reverberation.

 Prone

Duration: 2 turns

DC 10  Constitution saving throw

• The affected creature cannot move or take  Actions,  Bonus Actions, or  Reactions, and has Disadvantage on Strength and Dexterity saving throws.
• Attacks against a Prone creature have Advantage if made within 3 m / 10 ft of the creature.
• A Prone creature must spend half its Movement Speed to stand up.
  • A character with the Athlete feat spends only 1.5 m / 5 ft of Movement Speed to stand up.

Prone, Unconscious

Notes

• Since the penalty to Constitution saving throws is also applied to the saving throw against being knocked  Prone after stacking 5 turns of Reverberation, the DC for this saving throw is effectively 15.

Items that apply Reverberation

•  Boots of Stormy Clamour: When the wearer inflicts a condition upon a hostile creature, they also inflict 2 turns of  Reverberation.
•  Gloves of Belligerent Skies: When the wielder deals ⁠Radiant, ⁠Lightning, or ⁠Thunder damage, apply 2 turns of  Reverberation to the target(s).
•  Markoheshkir: Grants  Kereska's Favour which can grant  Bone-shaking Thunder: When you deal spell damage, inflict 2 turns of  Reverberation upon the target. [As well as other benefits]
•  Spineshudder Amulet: When the wearer deals damage with a ranged Spell Attack, inflict 2 turns of  Reverberation on the target(s).

Items that interact with Reverberation

•  Ring of Absolute Force: If the wearer bears the Absolute's brand, they deal 1 additional Thunder damage with Thunder damage spells and attacks. [Currently works even if the wearer is not branded]
•  Ring of Spiteful Thunder: When the wearer deals ⁠Thunder damage to a  Reverberating creature, it becomes  Dazed unless it succeeds a Constitution Saving Throw.
•  Thunderskin Cloak: When a creature with  Reverberation deals damage to the wearer, the creature needs to make a Constitution Saving Throw or become  Dazed.
• Everything in the Thunder set combos with  Gloves of Belligerent Skies and  Ring of Spiteful Thunder. It further fits thematically: 5 stacks of  Reverberation deal ⁠Thunder damage and creatures immune to ⁠Thunder cannot receive a stack of  Reverberation.

Bugs

• Until Patch #3, Reverberation was bugged. While it applied the stacking penalties to Strength, Dexterity, and Constitution Saving Throws, it did not deal thunder damage and prone. As of Patch #3, now works as described.
• The different items that can apply Reverberation do not all work as expected from their description.
• Creatures knocked  Prone by  Reverberation occasionally do skip their next turn unlike other Sources of Prone.
