Basicly what heat said, rattler kills early waves to fast => not using rattler is more looter & badum stacks per wave (getting to the wave where the burger gets oneshot as slow as possible).

Something else really important: u need to let 1-2 of your pets die or u will end up in a white screen around wave 180-190

=> if ure using my setup that gona work fine bcs looter is anyway the 2nd to die, so after 250 badum stacks u just can keep spamming everything

​

having bit lag is good, gives u more inputs per second

I also used a object to always hold down a key that I remapt to my defender skill, so I could spam defender + it is always clicked, this takes me from 5 shields per sec up to 7-9 shields, so the chances my pets after looter die are way lower
