Skills with battlefield cooldown can't be used straight away. Prompt skills only let you use it before non-prompt skill although your positioning or initiative is lower( when the situation is prompt skill vs prompt skill then positioning or initiative will be in the play) . On the other hand, skills with no battlefield cooldown can be used at first like 2 star Neji or 2 star Hinata or 2 star Shikamaru and so on ..
