By the time he'd reached the third floor, Vincent felt the entirety of the paralysis wear off of him. Heeding the warning of Alexander and Senna, he stayed away from the entrance to the fourth floor and instead chose to examine the mass of gelatinous corpses spread over the surface of the third. He'd already gathered a substantial amount of Poison Slime residue from what was left on his coat (which he'd carefully scraped clean with a knife- what remained of the Slime made it too dangerous to wear, but not to carry with a gloved hand), so he focused on collecting the Acid Slime. 

Or at least, he'd intended to collect it before he'd been fed some additional information on its properties. He didn't exactly consider any of the empty vials he had in his case 'enchanted', and he didn't feel like potentially sacrificing one of them to the slime to find out if they would be able to contain the residue. Instead, he just collected what he could of the Poison Slime splattered across the floor, filling up his remaining two vials for four full total. 

With that done, he remembered the other piece of information he'd been given, about the statue- spying it at the edge of the room, by the stairs to the fourth floor, he carefully made his way over to it, and carefully nicking his finger with the edge of one of his knives, pressed the bleeding tip to it. 

About a moment later, he took a step back, a little spooked by the new voice that had shot through his mind and described in detail what he'd only been given a rough explanation of before. Another moment passed, and he just shook his head. He'd already heard about previous happenings in the dungeon when Thoth let her mouth slip, this wasn't too big a surprise.

Rather than use the statue immediately, however, he decided to turn and go back the way he came. Maybe someone else was making their way down- even if they weren't, he appreciated the ability to move freely again too much at that moment.

That, and he had an idea. From one of his pockets, he produced the flask that had contained the 'Intermediate Antitoxin'- he doubted any of his vials could properly contain the Acid Slime, but perhaps one belonging to a God would do the trick? 

So, crouching by the pile of residue, he carefully gripped the base of the flask with his thumb and forefinger, and slowly pushed the mouth through the acidic puddle...
