Prime Matter and Certain Doom

[FreeTrojanVirus]

I'm looking for a way to survive Certain Doom, my first idea is to ask if Certain Doom is a pure attack that can be reflected with Exquisite Mirror? Or perhaps I need a certain amount of hp to survive?

[Capt. W. Schwartz]

Mirrors do not not help.
As for Max HP, The attack will be around 10x you current max HP, so more HP won't help.
The only solution I have found is to stack your own pure damage, other than that just have to get lucky.

Example: I made it to loop 51 last weekend, still had all my revives but then got destroyed by 3 PM CDs in a row. The only thing I can think of is I had just swapped from a weapon with very high Pure Damage to a weapon with out PD, and lowered my total PD by 20-30%.

kill them within 6sec, that's it.

I stopped using battlegrounds unless I have a very specific reason to use them now. If you're trying to go for a long loop you can't have battlegrounds due to prime minister spawns that will end your run every time.
