This glitch requires Genis to have used Indignation 50 times and have the EX-Skill Spell Charge (EX-Gem Lvl 4). When in Overlimit, cast Indignation to cast Indignation Judgment. Hold the tech button to delay the spell, and then press the basic attack button to charge the spell. Quickly cast Indignation a second time, but let it cast this time. You can now use your charged Indignation Judgment at any time by pressing the basic attack button twice. Video here.
