Skullshatterer Premium First Encounter (IS#3)

Looks really cool, reminds me of Vendetta from CC#12.
The hardest aspect of this map does not come from the boss itself, but the conditions. Basically if you mess up your team comp, you are fucked as DP regen is damn slow and you can't even redeploy in time. Attacks from the boss can one shot your operators. You have even less ATK, so Art damage dealers should be prioritized over physical damage dealers. Furthermore, the fact that enemies spawn and start moving too quickly making the stage even harder.
