Did you recently leave/get kicked from a group while having some levels into group skill?
That is the most common form of power drop.

it seems if u have 3x 4 star ninjas..somehow u get more stats on ur main..if uhave 3x 5 star..again more stats...and yea i experienced power rises and drops just by leveling or awakening ninjas that were not in the lineup

yeah I left from a group
wait if I join that same group I will have those powers back

I did leave from a group called legends if I join that same group will I get my powers back

you can join any group and get you power back.

You'll get powers back by joining any groups of high enough level.

YESSS so any group right and my powers will be restored full amount as before? don't matter if I join lgnds or akatsuki

so lets say I upgrade before I join the group and during that upgrtion i gain some powers, that power will add to the power i had before quitting the group s it will go higher right?

You may get the same upgrade before you left your former Group as long as the new Group youre joining in has the same level as your old one. Hope this helps.
;P

Groups have something called group skills when you train those it adds to your power. When you leave a group you lose that boost, but if you join any group of same level or higher than the one you left you'll gain that power back.

The power you gain adds to your current power so yes, if you upgrade your current power and join a group again you power will be what you have now plus your group skills.

yeah bcos the group increase your power a bit, but only staying inn.

Your group skill level will remein the same in every group you join. However, you'll resceive power equivalent to the max skill level of the group you're in, if you're over it. So, a newly created group of one person won't do. Once the max level is increaced, you'll automatically receive the appropriate power boost. Rince and repeat, until you reach your previous skill level and are eble to learn once again.
