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).
