TL;DR: Use a 1500 CP Poliwrath with Mud Shot and Power-Up Punch against Blanche in Great League, and don’t swipe any bubbles. Quest is done in 1 battle or 3 minutes.
This has been posted before when people were working on the 200 super effective charged moves for the level 43 quest, and I personally learned the trick from that post. But now that we have regular field research quests that reward Mega Energy for 10 SE charged moves, I figured it might be worth a repost.
What you need
A Poliwrath under 1500 CP, with fast move Mud Shot and charged move Power-Up Punch.
What you do
- Do a training battle with Blanche in Great League. This can be found at the bottom of the “Battle” tab.
- Use Poliwrath in the lead, followed by two random 1500 CP Pokemon. (Blanche always uses Sneasel, Sealeo and Snowy Castform.)
- In the battle, use a Power-Up Punch whenever it’s charged up.
- Do not swipe any bubbles during the charged move animation, until you already reached ~10 charged moves. This will ensure you do minimal damage (25% of the move’s actual power).
- Once you count to 9 or 10 charged moves, you can then swipe all bubbles to do full damage.
Without any bubbles, it typically takes 3-4 PuPs to kill Sneasel, 4-5 for Sealeo, and 4-5 for Castform. So I typically don’t swipe any bubbles against Sneasel and Sealeo, then swipe all or most bubbles against Castform (would take 2-3 PuPs to kill it). This works even if you’re not consciously keeping track of how many charged moves you’ve used.
Many alternatives are available, such as Medicham with Psycho Cut/Power-Up Punch against GL Blanche, Politoed with Mud Shot/Weather Ball against GL Candela, or a Mud Shot/Mud Bomb user (Whiscash, Marshtomp) against GL Candela.
