Oolas Lab Flux Matrix

I have been doing Oolas Lab solo and on level 2 theres the indestructible golem that you need to kill with the charged flux matrix for the key.

Problem: The flux matrix does not work reliably. more often than not it does not do its supposed 1337 dmg, instead it's just like 25 dmg and i have to try 10+ times.

Has anyone else encountered this issue? is there a way to get the 1337 dmg every time?

Thanks

dont use shadow form when pulling the golem

what a noob move, i should have thought of that. that was it!
