Mektul, the Forgemaster

Please fix Mektul, the Forgemaster, at last. He just refuses to come out of his molten gold. As a result, he's just a punching bag for ranged classes. I've already died 10 times on this boss in endgame just because he doesn't come out of his yellow puddle.

If I'm not mistaken, I never managed to kill him in the endgame. And I'm not used to dying on bosses.

P.S.
And finally fix the blue and red Chayula lights. They don't do anything.
