This is Acilis. Davis and Vivian worked on it for about 1 and a half years until it was perfected. It will melt rubber and most elastic materials, but it will never melt skin. Instead, when it comes in contact with the skin, it will cause paralysis within a couple minutes. Some monsters have adapted to not be affected by small amounts of Acilis, but most of them after taking a large dose will get paralyzed (there are only some exceptions.)

Stop exploring. I already told you at that other place, so I don't understand how you haven't learned your fucking lesson by now. We are superior to you, and we can jump out at any time and make you one of us. So this is your last warning, don't go any further.
