I know that raid power adds extra rolls for the rare rewards pool for Tera Raids. But when does it work?
Is it predetermined and only applies the extra rolls to new raids that show up on the map or does it apply the rolls to all existing raids? For example, if I had a 6 star raid that only granted me an Ability Capsule before using Raid Power, are those rewards fixed if I were to restart my game and do the raid again with Raid Power, or would Raid Power actually give me more rolls for other rare pool stuff like Herba Mystica?
Additionally, does Raid Power only apply to your own raids or would you get the extra rolls when you join someone else's raids?
By extension, does your own Raid Power mean others who join the raid reap the same rewards/get extra rolls themselves?
I don't usually use Raid Power but since the Chi-yu raid sometimes gives good Herba Drops, it might be useful for me to farm Herba. Any info on this is appreciated!
