The information above is false, about the poison damage on the staff. It is not "superior" to poison or toxic mist, except in the case of something with high hp. Poison spores scales drastically with the opponents maximum hp, so it USED to be better then poison mist, even in pvp. Now, it is quite a bit weaker (tested on players with roughly 2000 hp) then poison mist UNTIL the enemy has about 4000 hp or higher, which then it is marginally better. bosses like pontiff on higher NG's will make it scale much much higher, as high as 113 per tick, whereas normal poison mist will still be about 16-18 damage.
