Text of the ability reads:

"You and nearby allies gain +35 Enhancement bonus to resist Energy for 1 minute per character level.(Includes Acid, Cold, Electric, Fire, and Sonic.) nnSpell-Like Ability: This ability benefits from your Metamagic Feats (such as Quicken) without paying the normal additional spell point cost."

It actually only has a duration based on my cleric level (5). I am a Bard (7) Cleric (5). with Extend, the duration is 10 minutes.

Either the tooltip is wrong, (other than the nnSpell-Like Ability typo), or it is bugged.

Would love the duration to be based on character level as listed.
