Some adjustments that would make the boss more pleasant:

-The shark pools appear randomly to any member of the pt, it would be more useful if you indicate who the shark pool is going to attack, perhaps with an icon on their head. Then the pt could put together a better strategy.

-The shark pools appear and disappear quickly, there is no time to hit the boss or charge attacks, much less when combined with the horde of beetles. It would be more manageable if the pools changed places less times, or also that the pools remain in one place for longer.

-Lightning strikes very often, and they are difficult to evade, a good war can resist it, but rogues and mages usually die in one hit. It would be easier to evade if you added a warning or some red zone, indicating where the rays are going to strike.

Thank you anyway.
