Big strong team
Big strong team do much damage. Makes sense, right? Right! As you level up your team and use stronger level Pokémon, your team level will go up, and you'll, well, survive that much longer in battle, and do more damage.
Yeah, this is an obvious one, but it's still important. If you're struggling to do a mission, double check you have the very strongest Pokémon available to you in your team, and maybe go back to older, easier missions to grind for experience.
There's one more important thing you can get from grinding…
Power stones are unique to Pokémon Quest, and they act as simple equippable items you can give to your Pokémon to increase their stats.
Health boosts, defense boosts and strength boosts, with certain stones even giving additional buffs, such as an increase critical hit rate.
Gaining experience and levels will give you more slots for power stones, so continue to level up, and make sure all of your power stone slots are filled whenever possible.
You can rush into battle and mash away at attacks as soon as you're able, but that's not really the best way to go about things. Remember, defensive techniques are as important to battle as offensive.
Voltorb, for example, has Taunt, bringing other enemies towards him and making them ignore the rest of your team. It's essentially a bit of a sacrificial move, but lets your other, potentially less hardy Pokémon, do the damage.
All out aggression
When the time is right you really need to let loose, just pushing out out all of the damage possible.
All of your moves have cooldowns of course, but they don't last that long, and in these situations, often against bosses, you'll be wanting to use all of your moves, but keep a few things in mind.
Mainly, if there's recoil damage, the position of your Pokémon relative to the enemy, which moves might move you out of harm's way after, and whether or not you'll have time to Scatter.
It might be the most important move in any battle. Tapping the icon in the bottom right will make your Pokémon run for it, and it's the best way to avoid damage.
Really, the only issue is that walls can get in the way, and will prevent you from running. Oh no.
Another small problem is that, if you're in the middle of an attack animation, the attacking mons won't receive the scatter order and will run into danger. Oh no.
