Final gym help!

[SuperNova]

Spoiler

I am at Saphira's gym and that challenge is quite something, I am stuck after stopping magneton as I don't have the time to get back to the chest after I defeat it and even with full health on the chest it is destroyed. Any tips?

I guess my best tip would be to disable speedup inbetween fights. Helps you navigate better and you'll lose less time bonking into walls.

Also, the warning for magneton comes very early. You should try to anticipate the other enemies and once you defeat them start running towards magneton, even if the chest hasn't been lifted yet

after defeating magneton, go straight to the chest. the guard that spawns after magneton is not your priority. he will move from the middle path but you need to move back to the chest from the right path at the same time with him.
