Power have nothing to do with level freezing. For what reason should he level freeze? To get one of the top3 prizes in swb? He is f2p, that option does not exist for him, overall now that he is 81. level freezing does not help, just prevent him from getting free power from cultivation, awakening, character progress and equipment level up with coins.

What he needs to do is to give himself midterm goals, go only for 'good for his situation' power in events and use recources only when a rebate is available and not necessarily every time that rebate appears (and try to collect a meta team).

What i mean is: do not use coupons for things you will eventually get for free in shops, common events and monthly event.

When in redeem shops are available unbound rune packets and myoboku gifts buy them since up to level 8 summon cultivation and up to page 7 myoboku cultivation they are currently the best way to get good power for low prices.

If you tell us what are your charms, runes, summon runes, magatamas and tactics levels we can tell you on what to focus the most (you are free to play, i suggest you to select a defensive tactics, like sun move, to level up. Ghost kill is whale only).

That is only because you are lucky enough to be in an old cluster where a lot of people had a ton of hoarded exp from the previous level caps so in your field there are not 6-7 other competitive f2p like you that had the luck to avoid leveling up a lot like you did, so you just meet 2-3 whales you can not beat and 5-6 low cashers that were very lazy in the past and that were lucky to be in your same situation, people that still, somehow, you can beat.

In new server clusters a lot of f2p, low cashers and whales are level freezing so the situation is not the same you are facing.

Would you still level freeze if in your sage there were 5 whales and 6-7 low cashers you can't hope to beat that let you be always at best 4th-5th in your side?

Because this is the situation the op is facing almost for sure.

I was 35k at level 80, at the time was meaningless if not counterproductive to level freeze so i never did it. I know it because i remember i was at that power when i beat exam 100 and at that time there was no summon cultivation, no charms, no myoboku cultivation and no ninja bonds nor there was the power granted by the two group summon. I am prettt sure the perfect f2p that makes no mistake and that does not level freeze right now is at 50k at level 80 (i began cashing a bit after level 85 and i also made some mistakes, like buying konan with coupons at that time).

If you are behind in power Minato hokage works the best with azure fang since let you spread poison and she can heal him + you are making her more resistant thanks to the buff to res (for example you c*e gaara, minato, bee sst team) or with crimson fist in the well renown blitz team with gaara/wb asuma and iruka. Imho you should try one of those two. Wind and fire main with him work fine when you are at comparable power with your enemies (the reason is you need to let him stack and the only ways are by letting him survive with shields or healings).
