Burnout II duration 1 hour?
 

All info I can find on this spell (lucy, alla etc.) says the duration of this spell is 1 hour. Now without any messages for spells wearing off it is hard to say when it does - but from my observations my pets start to perform markedly less well after 11 mins or so.

Any others have input on this?

Says 9.7 minutes to 15 minutes depending on level. You can double check this in the spells_us.txt file if you really wanted to, but it's probably correct.

Thanks for the link, useful resource.

You can always cast the DS spell on yourself and just recast Burnout whenever the DS wears off. They should be roughly the same duration per level.
