Lesser Vigor lasts for 10 rounds + 1 round/level, up to 15 rounds. If I use Extend Spell on it, is the limit still 15 rounds?

  • \$\begingroup\$ no, it would cost 6 times more, and heal twice as much, bad deal \$\endgroup\$

1 Answer 1


I found the following Sage Advice/FAQ quotes on the playground.

The main quote:

Main 3.5 FAQ, Revision 06/30/2008, p. 40

Q: The Vigor series of spells (CD) raise an interesting question. Does the built-in maximum duration of each spell limitation override the effect of the Extend Spell feat?

A: Yes. Extend Spell still increases the spell’s duration, but only up to the spell’s listed maximum duration. Use either the normal maximum duration or the doubled duration, whichever is less. If a 7th-level druid used Extend Spell on her Vigor spell, the duration could not increase beyond 25 rounds.

Which is corroborated by a second quote:

Main 3.5 FAQ, Revision 06/30/2008, p. 92

Q: The Mass Lesser Vigor spell has a fixed range (of 20 feet), which makes it eligible for the revised Persistent Spell feat in P.G.. Does that mean a 17th-level druid could use a 9th-level spell slot to give nine creatures fast healing 1 for 24 hours, or does the built-in limit of 25 rounds make that pointless?

A: Unlike Extend Spell, Persistent Spell replaces a spell’s normal duration with a new duration of 24 hours. In this case, the effect overrides the normal maximum duration of the spell, so it would indeed grant nine creatures fast healing 1 for 24 hours (a pretty reasonable effect for a 9th-level spell).

The FAQ itself can be downloaded here; I have amended the quotes with the latest revision.

The FAQ is not necessarily authoritative, and sometimes of dubious quality; it is up to you whether you choose to follow its ruling or not.

If you do choose to follow them, then the rulings are clear:

  • Extend Spell doubles the normal spell duration of a spell, up to the specified maximum duration if any.
  • Persist Spell simply overrides any duration to 24 hours.
