Hey Kaida,

Thank you for bringing this to our attention. We will pass this off to development and get this clarified for you. Should the TP gain for Multishot attacks require any adjustments or fixes, they will be posted on the Official Final Fantasy XIV Lodestone site.

If we receive any updates or need any additional information, we may unlock the thread and post here.

Thank you,
