PK Ground is a PSI ability in Mother 3. It works on all enemies, hitting five times and dividing the damage between all of the targets. The exact damage is determined by the maximum HP of the foe it targets (it does 5% of the enemy's max), making it very effective against bosses (with the exception of the King Statue, which is immune). PK Ground is learned in Mother 3 by Kumatora. It cannot be reflected by PSI shields.
