One duel in a drowned cathedral: a souls-like demo that plays in the browser.
Evensong is a single souls-like boss duel that plays in the browser. A pilgrim with a sword, a shield and a lantern wades into a drowned cathedral lit by candles floating on the water, and faces Ondine, Cantor of the Drowned Choir: a winged giant, 3.67 times his size, who fights with a great sword and with rings and blades of light.
The fight was first tuned hard and filmed that way, then made easier for release. The author kept the filmed balance available as a separate rule set.
The model that made it is not stated by the author.
Sweep, Cleave, Lunge, Spin, Leap, Stomp, Chorale, Hymn, Descant and the Tide.
