Similar to Lv7, Lv8 didn’t have significant changes outside of a floor swap; in this case the previous boss, Sandalphon, swaps places with Lucifer to the first floor. This doesn’t change the dungeon difficulty for an awoken Greco-Roman god, but it does make things more convenient. Sandalphon is the hardest floor for this strategy so if you screw up on him you only have to redo the first floor instead of the entire dungeon.
To take advantage of this, I decided to be a bit more daring in killing him. Before I’d play it safe, but this time I got him within a pixel or two of 50% HP. This way I could use GOdin’s nuke to get him below 50%, switching him to water, getting the benefit of elemental advantage while avoiding the 10-turn god bind. This, of course, made him trivial to kill.
Challenge Dungeons 6 appears to bring the first significant jump in difficulty. The new Lv8 loses Raphael, Sandalphon and Lucifer and swaps in Athena, Hera-Sowilo and Zeus Vulcan. Hera-Sowilo brings her own set of challenges, but shouldn’t be difficult for an awoken Greco-Roman lead to deal with. The real problem is Zeus Vulcan which pretty much rules out using Ceres. You’d need to do over 5.5 million burst on the first turn to get him to switch to light. This would be easy for Neptune, but I’m not sure I want to invest in the team. I also don’t think my current Verdandi team can handle it, either. It looks like I’ll actually have to put some effort into beating the next version of this dungeon.
