Void questions

Questions about void monsters, not questions that are void.
I was wondering if the lichens had posin ressist, since they inflict posin. Also, the wiki said that they were weak to elemental. Is that true/are there any weaknesses? And do monster specific damage buffs help whatsoever?

Dang, I figured VV might be a good counter for the swarm seed. I feel the need to test this elemental/shadow thing, need to make a shadow tech and a prisma tech alchemer...
Oh, and also, I wasn't sure when I did the snarby lair, but does the swarm seed decrease attack speed and charge time reduction or just movement speed?

It just affects movement speed. One of my favorite tactics for running through the unknown passage is to use Flourish combos to move faster than walking speed on the swarm seed. I think you could also use the Rocket Hammer to go even faster.

I used sword combos to get through as well, even worked with CIV.

DVS and WRH work wonders for getting through the unknown passage for that reason.

I'm still thinking that rocket hammer would be better.
They are slimes. Elemental does slightly more damage than usual, but not as much as shadow.
Idk about poison, for I never tried it. I would assume they are poison immune.
