Runes

Adds a Keystone loadout slot to every survivor, vanilla or modded, with six League-style keystones. Originally part of SettMod, now usable by everyone.

Runes was created under Riot Games' "Legal Jibber Jabber" policy using assets owned by Riot Games. Riot Games does not endorse or sponsor this project.

Keystones

Keystone	Effect (default config)
Conqueror	Hits grant a stack, up to 12. Each stack gives +0.6 base damage (+0.045 every 4 levels). At max stacks, heal for 6% of damage dealt.
Lethal Tempo	Hits grant a stack, up to 6. Each stack gives +10% attack speed (60% at max).
Stormraider's Surge	Dealing 25% of an enemy's max health within 3s gives +48% movement speed and 50% slow resistance for 4s. No cooldown: it can trigger again as soon as it ends. Replaces Phase Rush, and takes over its loadout pick.
Electrocute	Every 3 hits within 3s, on any enemies, strike the enemy you hit with lightning for 200% damage (+75% every 4 levels). Stacks stay with you, so kills don't waste them; if the third hit is a kill, the lightning jumps to the nearest enemy. No cooldown.
Grasp of the Undying	Every 4s, your next hit deals bonus damage equal to 5% of your max health, heals you for 2% of your max health, and permanently gives +1 max health for the rest of the run.

A hit is anything with a proc coefficient above 0, so damage-over-time ticks don't build stacks. Stormraider's Surge is the exception: all damage counts toward its threshold. Stacks start falling off after 4s (Conqueror) or 6s (Lethal Tempo) without landing a hit.

Every survivor defaults to No Keystone, so nothing changes until you pick one in the loadout screen.

Config

BepInEx/config/com.Lemonlust.Runes.cfg

• General → Enable For All Survivors: turn off to give the slot only to survivors whose mod opts in.
• Survivors: one toggle per survivor. Filled in after the first launch.
• One section per keystone with all its numbers. Descriptions in game update to match.

In multiplayer, everyone should use the same Survivors toggles. Turning a survivor off removes a loadout slot, and players whose configs disagree will see mismatched loadouts.

For modders

Reference Runes.dll, add a dependency, and call the API from your plugin's Awake:

[BepInDependency(Runes.KeystonePlugin.GUID)]
public class MyPlugin : BaseUnityPlugin
{
    void Awake()
    {
        // ...after your body prefab exists
        Runes.KeystoneAPI.RegisterSurvivor(myBodyPrefab); // slot even if "all survivors" is off
        // or Runes.KeystoneAPI.ExcludeSurvivor(myBodyPrefab);
    }
}

KeystoneAPI.GetKeystone(body) returns the keystone a body has selected, and the buff defs are exposed for anyone who wants to react to stacks.
