Multifocus (3.5e Feat)
From D&D Wiki
Example: Rathe is a 30th level Psion (Telepath) who has taken Epic Psionic Focus twice (at 21st and 23rd level) and Multifocus (at 24th level). Rathe expends his psionic focus to quicken, twin, and maximize a power he manifests. He then uses his Multifocus feat by succeeding on a DC 25 Concentration check to regain his psionic focus to make use of his Mental Leap feat. Rathe uses his Multifocus feat again by succeeding on a DC 35 Concentration check to regain focus so he can maximize, twin, and empower another power he uses. If Rathe had not chosen to expend his psionic focus on the second power after he had regained it with the DC 35 Concentration check he could benefit from his Speed Of Thought feat on his next turn because he would have psionic focus.
