Summoned Skeletons from the Grimoire only last 5 minutes. That's not enough time for an army.

Summon Forever gives you complete control over how long your Undead stick around.

What this mod does

Makes your summoned Risen Knights last forever (until killed)
Or set a custom duration in seconds (10s, 60s, whatever you want)
Works with modded summons to last forever too such as Wolf Summon Spellbooks

Why I made this

Summoning skeletons from bone piles is one of the coolest features in the game. But disappearing after 5 minutes felt wrong. I wanted my undead army to fight by my side until the end.

Now they do.

Customisation

-1 = Forever (default) - Summons live until killed
0 = Default game behavior (5 minutes)
Any number = Custom duration in seconds
Config generates automatically in your mods folder:

\mods\SummonForever\config.json

Planned / to hopefully come

Summons survive when player disconnects
Randomly nametagged summons
Indicator for summon duration remaining
Whatever else comes to mind…
