the new changes to magnus and empress

ok so i have read before on the nexon forums that empress i think in red got changed back to the version before unleashed
now ive been browsing through the extractions and ive noticed empress and magnus got another changed and since im quite a bit of a noob i would like to know if its possible to summarize it

The bosses in the new patch are for boss arena. Or atleast I'm pretty sure they are.

im not entirely sure
considering empress in boss arena has way less than 63b hp
and same goes for magnus having 122b

The bosses in the arena scale to your level, like PQ mobs.

Empress now one shots you with dark genesis at future ereve. She also has no heal now.

Magnus got his green aura attack fixed, but now his dash is somewhat broken.

Those are basically the changes.

so figures that they did change
since they had to re-add the magnus data to the game and empress also got a complete change since she doesnt heal anymore
so empress equips will now go up in price quite a bit
