It must have been over 10 years since I've taken down the Black Omen. With all the time spent in the Lost Sanctum going through the Black Omen was pretty easy. Only a few enemies put up a challenge and it was the ones with the ability to knock HP down to 1. I kept the Crono, Marle, and Magus party throughout.
Once I took down Queen Zeal and the Mammon Machine it was time to face Lavos. Crono has beaten the void and is ready for Lavos this time. After recreating previous boss battles, Lavos unleashed its primary attacks. This was the first time that the group has suffered major damage in awhile.
