Oh, the relic in the queen's room, I see. Yes, that one, you can jump all the way and without touching the water to get to. Anyway, I have to say, the Queen is so easy when you got the gas mask.... It's actually unfair to her!! The first time I fought her, I have the gas mask but never put it on ( I was thinking having it in my inventory will automatically protect me from poison
... That was one very tough fight - without the gas mask on
)
