Question about Grey Star book 1 - Use of Tarama Flower seeds

[journeyman]

Hi everyone, can someone help me with this question please? I have reached the point where I've rescued the herb warden and received among other things, 3 Tarama flower seeds. In the book, it says that one seed permits the use of a magical power or use of the wizard's staff without the loss of any willpower points. Does that mean for just one round of combat or for the entire duration of the combat? Also, what about the rule of multiplying enemy EP loss when using the wizard's staff? I'm assuming this doesn't apply if we've used one of the seeds otherwise we could just choose a large number and kill them easily in one round of combat knowing we won't lose any WP points. Could someone clarify please?
Thank you,
Journeyman

I always found this confusing as well.

There's an entry for Tarama in the Readers' Handbook:

The seeds of this plant are highly sought after by those trained in the magical arts. Swallowing a single seed prior to the working of a spell will allow it to be cast without loss of WILLPOWER. These benefits do not apply to the use of WILLPOWER to charge a Wizard's Staff in combat although they do help when making long distance attacks.
