WOW. The four elements were certainly a huge step up from the past bosses.. Congratulations, you made these guys REALLY rough.
Milon was a joke, but I didn't expect anything different..
Then rubicant came out.


Those two pictures sum up the Rubicant segment of my battle.. Lol. My four top members were laid out the entire time, but Cursed ring > Rubicant. I slapped a silencer knife on her and just wailed on him til he died.
... Then immediately reset when the water guy hit her four times and tsunami'd to do just over her max health. Next try I put blur on her before killing rubicant, then Life2'd Cecil and struggled for a while getting everyone up. Then I kept heals rolling, used potions whenever I needed a quick boost before a tsunami, and whittled him down over time.
The wind chick wasn't bad at all, the 'weak' (Forgot what it was called) spell on everyone was annoying, but I got everyone up quickly and defeated her with everyone on their feet.

All in all, took a grand total of 2 resets. The tsunami guy was the only one who could literally kill me. Proceeding on now.
