Upgrading all spells from round to minute ?

[Roncorps]

Is there a way to upgrade spells that have a duration in rounds to a duration in minute ? Like a feat or etc. that make you cast all your rounds spell into minutes spells ?

Thanks !

Extend metamagic, four pearls of power and four extra appropriately scheduled actions. Or nine and nine without extend.

Metamagic: Extend doubles their duration, Persist makes it last 24 hours.

Used to be, but it was far to insane.

Not in PF. In Pathfinder, Persist makes it force a second save if the first was successful. Much more reasonable than 24 hour buffs.

Thank for the info. Extend just double the duration, so it's a no-no. I was asking this because I've got the Enduring Blessing from the Hierophant mythic path and I wanted to see if there was a way to get round to minute and use the path ability to up them to 24h for free. At least, it work for 1 minute and 10 minutes spell.
