After reaching a Cursed Energy score of 20, you have learned how to use your maximum output, which consists of techniques with the highest possible cursed energy output channelled into them. As a bonus action, you can spend twice as much cursed energy to amplify your cursed energy output on one of your techniques, making it gain one of the following benefits the next time it is cast:
- The technique’s range is increased by half its original range, rounded up to the nearest 5 feet. For example, a technique with a 10-foot range would become a technique with a 15-foot range. This range increase does not work with touch-based techniques.
- The technique’s damage dice are increased by half of its original dice, rounded up. For example, a technique with 10d10 dice of damage would add 5d10 dice of damage to the total damage dice.
- The technique’s bonus to hit is increased by half of its original bonus, rounded up. For example, a technique with a +7 to hit would add a +4 to hit in its maximum output form. DCs increase by half your proficiency bonus (rounded down).
- The technique’s duration is increased by half of its original duration. For example, a technique that lasts 1 minute would last 1 minute and 5 rounds.
