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.

Properties

 If already applied: add to duration

 More properties:

• MultiplyEffectsByDuration

Condition: Prone

 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.

Bugs

• Despite the description, no such mechanics exist to prevent Thunder-immune creatures from receiving Reverberation.
• In real-time mode, none of the effects described for applying 5 or more turns occur but the duration is still capped at 5 turns.
• If the saving throw for  Prone triggers any reaction which prompts for confirmation, Prone is not applied and the saving throw is not recorded in the Combat Log regardless of the result or whether any reactions are selected. If the saving throw was caused by multiple sources of Reverberation, multiple consecutive confirmation prompts might appear instead of one and the text line which names the involved entities is missing.

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.
