hunter credo grants you +20mm
you can gain this benefit and die without completing the credo, which will set your MM to around 10ish
then you can bury your corpse and you'll regain even more MM
then you can start the credo again and it will bump up your MM even more, rinse and repeat
can be applied to any credo that does the same, but hunter is the most abuseable as the benefit is the very first benefit, and is much larger.
most abuseable by just making an alt first to spam kill over and over and raise their mm for, as 10k lp is very much cheaper than the cost to raise MM higher.
