Notes
- The extra damage inflicted also adds to spell attacks, such as Fire Bolt and each individual beam of Eldritch Blast.
- WARNING, the self-damage each round does still induce Concentration checks if you are using a Concentration spell. If you want to use a particularly important one like Haste alongside Psionic Overload, it would be better to have an ally cast it on you.
