The unique Improved Bardic Inspiration (obtained from Alfira by playing music with her at Moonrise Towers) is not working properly.
If cast during dialogue - the buff does not apply its +1d12 bonus to that particular ability check (instead the player just indefinitely keeps the buff for all other future checks)
Once a party member has the buff - the buff never gets consumed by any ability checks whatsoever (thus it permanently provides a +1d12 bonus to all ability checks indefinitely)
Cannot be used as a reaction - instead the buff uses passive-toggles for whatever reason (it should use the reaction system instead of toggles, like the regular Bardic Inspiration)
*As can be seen casting the Improved Bardic Inspirationduring dialogue will not apply its 1d12 bonus to that ability check, the player just keeps the buff instead.
*As can be seen theImproved Bardic Inspirationnever gets consumed by any ability checks, so it can be indefinitely used forever as a permanent 1d12 buff.
