Re: Appease-mint vs Conceal-mint
The best levels are 2,4 and 7 as they knock time off the refresh rate and anything over 7 is incredibly expensive unless you're a mintionaire.
Both appeasemint and concealmint are good powermints that are very useful in arena, but i think if you're worried about zomboss battles you should go with appeasemint.
Bowling bulb and threepeater/ torchwood are usually pretty good against zomboss.
I think if i were you i would concentrate on levelling up the more useful powermints (about half of them) to levels 2,4 and 7 as they all bring something useful to the party.
While maxing out spearmint is an excellent idea, maxing out reinforcemint isn't unless you have a massive pile of mints.
Most of reinforcemints abilities are just as good at level 1 as higher levels (knockback and armour boost) and all higher levels do is decrease the refresh rate and allow peanut to spew peas a little longer.
I'm a big fan of reinforcemint but i recognise his limitations.
I sat down and wrote out a plan of powermint levels/ benefits and over time upgraded them as necessary now have maxed them out in two profiles, am currently taking my level 5 powermints to level 7 and have a level 1 profile as well.
The fandom site has tables showing the costs and benefits of each powermint and it costs a whopping 4,150 mints to buy and max out a powermint (enlightenmint excepted).
