Bloodhound Torment boss in the Shallows virtually impossible in the dark

I’m normally not one to gripe, but I cant help but feel that this fight is just a little ridiculous in its current state. I’m all for challenge, I love difficult games and thrive on learning the systems and adapting my playstyle to fit and overcome, but in this case the darkness of the arena makes this fight almost impossible to tactically approach in my opinion.

The fight is taking place in the trapdoor at the bottom of the tower in the shallows. Basically the Riven twins beefed up, at least it seems like them for the moveset, but I cant tell because even with a torch the room is essentially pitch black. I cant see the AOE pools he’s dropped down and I roll or walk into them. He also drops a massive number of these persistent plague pools all over the arena sometimes 10 or 12 at a time cutting off massive swathes of the space to fight - which of course I cant see.

I have no issue with the damage I’m doing, or the damage he’s doing with his melee or spell hits, but the Plague stuff in the dark is just absurd as there’s (unless I’m missing a way to light this arena up) simply no way to even respond to the game state because its so concealed in the darkness even holding a torch - without the torch the room is literally pitch black.

Does anyone have suggestions on how to light this place up or is this actually running as intended? If this is the way this fight is supposed to play out then I genuinely think it needs addressing. Perhaps giving the AOE pools a more visible glow or effect so I can at least see where they are to avoid them, illuminating the room to a higher degree of limiting the amount of AOE spam he can do would make this a less frustrating experience.
