A creature may have more
cybernetic attachments installed on its body can it can bear. However, the creature gains 1 negative level per
cybernetic attachment that exceeds its maximum allowed. For each negative level, the creature takes a -1 penalty on all
skill checks and
ability checks,
attack rolls, and
saving throws, and loses one effective level or Hit Die whenever level is used in a die roll or calculation. Further, a character with psionic powers loses the ability to manifest one power of the highest level she can manifest (player's choice), while a character with spellcasting ability loses the ability to cast one spell of the highest level he can cast. This loss persists until the negative level is removed.
