EldenRim

Fight Skyrim like Elden Ring. You play the whole of Skyrim Special Edition, with all of its NPCs and quests, using Elden Ring's combat rules and sounds. Both are read from your own copy of Elden Ring when the game starts.

What changes

• Weapons hit with Elden Ring's weights. Each Skyrim weapon class uses a real Elden Ring weapon's numbers, read from your regulation.bin: Dagger, Longsword, Battle Axe, Mace, Claymore, Greataxe, Great Mace and Longbow. Damage is scaled to Elden Ring's ratios against the Longsword.
• Stamina is the fight. Every swing costs the light-attack stamina of the matching Elden Ring weapon, and power attacks cost its heavy-attack stamina. Stamina refills fast in combat.
• Dodge. Press Jump with a weapon drawn to dodge: a quick hop with a short invincibility window, a stamina cost, and Elden Ring's roll sound.
• Poise and stagger. Enemies take Elden Ring poise damage from your hits. Each Skyrim enemy type uses the poise of an Elden Ring counterpart: dragons use Flying Dragon Agheel, giants the Fire Giant, trolls the Troll, draugr a Skeleton, and bandits a Godrick Soldier. Once their poise breaks, they stagger. Enemy hits break your poise in the same way.
• Limited healing. Only 4 healing potions work per fight, like flask charges. Your health doesn't regenerate in combat, and enemies hit harder.
• Elden Ring sounds. Drinking a potion plays the flask gulps, dodging plays the roll, and dying plays Elden Ring's death sound before Skyrim's normal reload.

Needs

• The Elder Scrolls V: Skyrim Special Edition (Steam).
• ELDEN RING (Steam). It is never started or changed; the mod only reads its files.

How it works

When you press Play, eldenskyrim-setup.exe runs before Skyrim starts. It does four things:

1. Reads Elden Ring's regulation.bin and sound banks from your install.
2. Converts the sounds to Data/Sound/FX/EldenSkyrim/*.wav.
3. Writes Data/EldenSkyrim.esp.
4. Turns that plugin on in Plugins.txt.

On later runs it only rebuilds when your Elden Ring files change. setup.log lists every value it used.

Single player. It works on new and existing saves.
