You gain the benefits of a psionic focus without needing an external piece of gear.
Hacking. If hacked, the focus goes haywire. For the next minute, using any psionic power deals 1d6 psychic damage to you. This damage can’t be reduced or prevented in any way. In addition, you are rattled for the duration, and any saving throws you make against the psionic abilities of other creatures are made with disadvantage. The implant stabilizes automatically.
