That, and Duibhe might not have wanted to answer all the questions right then!

Nita keeps level with the batcat, acknowledging with an additional /Hold steady,/ before landing on the right spell and starting to fiddle with it.

The part about talking is mostly to iron out the usage of Duibhe's Name, which is essential for customizing the spell. She'll feel an odd ticking in her ears as Nita recites in the Speech - nothing painful, and even the intensity of the ticking fades over the course of the spellcasting.

The batcat will have to give an affirmative when the earplugs are at the right shape, but the calibration should go smoothly.
