On the event map, you need to collect feathers and drop them under the Elisah statue by pressing the space bar. Fill up the progress bar at the bottom of the map to defeat the Anvil God.
Once you have you winand consumables!
But watch out, the Anvil God will throw lazers at you and if you get hit by it you will die.
More information:
You can earn consumables from filling the bar. And can collect more than one feather (try to collect as many as possible)
Also, you can get consumables if you're dead, only if you can bring back at least 1 feather back and the bar has been filled up.
