- Sariel and Tarmiel had their Graces back then, Sariel used his offensively and both used them defensively.
- Ludoshel stated he needed to intervene, meaning he suspected Sariel and Tarmiel wouldn't succeed their mission. Note that he intervened before any sign of Indura happened. He intervened because Tarmiel/Sariel were getting pressured.
- Sariel and Tarmiel started off the fight confident and joking around, but pay attention as it goes on. Sariel's expression switches to shock and then shock/fear, which is when Ludoshel intervenes. Tarmiel stops talking and concentrates on holding off both Derieri and Galand, and he loses his smirk.
- Tarmiel's Ocean creation feat is the epitome of casual.
- Sariel/Tarmiel state that they're only about twice as powerful as "you Commandments" in general. Which is why Ludoshel felt he needed to intervene.
- Both Sariel and Tarmiel are damaged multiple times by Monspeet/Derieri/Galand.
- Monspeet/Derieri/Fraudrin all tank Omega Ark with barely any injury, despite it being an attempted kill-shot.
The evidence is overwhelming for the Commandments to scale to a large fraction of the Archangel's power, which is why I'm arguing for a 6-B rating, as AA are lower-end High 6-B. The Danafor feat would simply be a supporting feat but nothing important.
