Sekiro's Wolf fights in the Lands Between: posture, deflects, Mikiri counters, deathblows.

You are Sekiro's Wolf in the Lands Between. Elden Ring's own combat is replaced by Sekiro's: guard to block, tap guard as the blow lands to deflect, fill the enemy's posture bar, and finish with a deathblow. Perilous attacks flash the red kanji, thrusts can be punished with the Mikiri counter, and Unseen Aid gives you a second chance before the death screen.
Everything Sekiro brings is read from your own installed copy of Sekiro while the game runs; nothing from either game is included in the download.
Requires Elden Ring 2.7.2.0 and Sekiro: Shadows Die Twice installed. Single player, offline (Melty starts Elden Ring through ModEngine2 with Easy Anti-Cheat off).
Credits: the original Shinobi Ring by IaMaLegendBro (MIT), used with thanks. This Sharpened edition adds support for Elden Ring 2.7.2.0, fixes a crash when the sparring partner spawned, and retunes posture damage and recovery.
