This video was recorded in the Spiral Abyss May Waxing Phase.

These videos are more like team ideas to clear Floor 12 than damage showcases. Some of my artifacts on these teams are pretty bad so anyone with better artifacts should be able to clear even quicker. See below for more character and team information.

Constellations and 5-star weapons are not required but of course help. Most characters or weapons at level 90 would suffice at level 80 but I'd recommend levelling these characters to 90:
-Itto as DEF scalers benefit more from levels than ATK scalers
-Chiori for the same reason as Itto
-Bennett for a bigger attack buff

A mono geo team is a generally decent team but can struggle with elemental shields. The team has enough to destroy the cryo shields in chamber two and the rest of the chambers aren't much of a problem, considering you can do enough damage. For the second half, cryo is great for destroying electro shields in chambers two and three, whilst also being enough for the pyro shields. Pyro is great against the cryo shield and completes the melt team.

This is my (almost) Free-to-Play account that I started playing daily in 1.6. I have used 3 welkins so I hope my account could give F2P players an idea of what their account could look like after roughly 2.5/3 years of varied character usage or if they invest into a few teams for a year.
