[Bug?] Coloseum

I think i noticed two bugs there.

First is, like said in an other thread, Meteo isn't dropping Chips[in normal mode].
I made the normale mode about 30-40 times and got perins only from meteo.

Another thing is that Rockepeller could be bugged,
because I#m making only 1 DMG to him when my ATK is over ~40k
When I'm using a second weapon which wont give me more than ~40k ATK I'm doing regular DMG.
