Alternate description

A second source words this differently; both are kept rather than one being discarded.

Sharpens the mind of your defensive target's party, increasing energy regeneration by XX every sec.

Not in the emulator. This ability is recorded here but does not appear in the VGO Emulator build. It is kept because this archive records the game as it shipped — see everything else missing from it. Its figures are unverified.

As it was earlier

What guides written while Vanguard was running recorded for this ability. Kept beside the current figures rather than replacing them — the game was rebalanced across its life, so both are right for their own year.

Notes

Not present in the VGO Emulator build as of August 2026 — a player at the level cap went through the whole Psionicist spellbook and does not have it. Kept because this archive records the game as it shipped, not the emulator; the figures are the wiki's and unverified.
