Absolutely visually stunning, glad I didn't miss the vote.
The cannon perfectly conveys the sheer destructive force by first breaking atmospheric barriers, while the impact wreaks havoc on the earth, leaving lingering remnants of white glowing divine power inside the cracks as a constant reminder that this is where it struck after which the beam eventually dissipates in sparks, scattering into the atmosphere.
That said, the rune circles are just amazing.
Intricate runic designs of otherworldly conception silently signaling and gracefully summoning the eventual doom for those caught inside.
The rotating rune circles would make for an amazing standalone sfx in their own right, could I be so bold to politely request it?
Amazing.
