Dance!

[siegfriedliner]

So the dance! Feat works when you supress a target with an attack. I assume area-fire counts as it has the attack trait even though it's not an attack action ?

Yes, it works. Area/Auto are already considered attacks. Additionally, the new errata for the SF2E Core Rulebook FAQ indirectly also clarifies further in the question about Using Kill Steal on creatures failing their saves against Area/Auto Fire attacks, calling those attacks "hits" and treating them as Strikes.
