You can cast spells using your ability to channel energy.
Prerequisite: Knowledge (arcana) 24 ranks, Spellcraft 24 ranks, ability to turn or rebuke creatures, ability to cast 9th-level divine spells.
Benefit: You can spend one of your turn/rebuke undead attempts to cast spontaneously any divine spell you can normally prepare. When you attempt to spell siphon a spell, make a turning check and consult the following table to determine the maximum spell level you can attempt to spell siphon.
| Turning Check Result | Highest Level Spell Possible |
| 1 or lower | 0 level |
| 2-4 | 1st level |
| 5-7 | 2nd level |
| 8-10 | 3rd level |
| 11-13 | 4th level |
| 14-16 | 5th level |
| 17-19 | 6th level |
| 20-22 | 7th level |
| 23-25 | 8th level |
| 26 or higher | 9th level |
Once you determine the highest level spell you can spontaneously cast and have selected which spell you wish to cast, you can cast the spell just as if you had prepared it. You must supply any material components or foci the spell normally requires. Spell Siphoning is at least full-round action. If the spell you siphon has a casting time of a full-round action or longer, it takes an extra full-round action to cast the spell. You can apply metamagic feats to this spell, as long as the spell's effective level is not greater than the highest level spell possible set by the turning check. Each metamagic feat you apply, however, adds another full-round action to the casting time for the spell.
