How to learn

Granted by items:

• Markoheshkir

This spell is a variation of:
Kereska's Favour

Notes

• The in-game tooltip says this effect inflicts 1 turn of Reverberation, but it actually inflicts 2 turns.
• Applying Reverberation can only occur once per attack. A spell hitting multiple targets like  Shatter will only apply the condition to a single target.

Bugs

• The version of Destructive Wave granted by this condition still displays the individual variant spells ( Destructive Wave: Necrotic/ Destructive Wave: Radiant) as costing a  Level 5 Spell Slot. Though no actual spell slot cost is incurred by the caster, these variants will still activate effects which trigger when spending spell slots.
