Be aware that if you're insane like me and need to have S knowledge on every mob, getting S knowledge on all the Vahmalkea mobs will take you quite a while. I'm missing apex lucretia and i've easily made around 250 of these scrolls. Also, the drop rate of the chips is higher if you do the legit vahmalkea and not the solo version, so what i recommend if you're not doing it in a group is to just go through the easy mobs. I am not certain if the drop rate buffs work on those. I've read one place online saying it does but it was not an official source. PA DID make a list that can be found online of what is affected by drop rate buffs and what isn't, but somehow Atoraxxion doesn't appear anywhere on the list.

Also as far as I know, all the knowledge obtainable from these scrolls can ONLY be obtained from these scrolls, killing the mobs won't work (and in the case of Apex Lucretia, they're not even a mob you can kill anyway)
