Wither Spawn Fix WSA Compatible Mod Guide

Fixing Wither Spawns Without Losing the Altar Animation

The Wither Spawn Fix WSA Compatible Mod addresses a specific problem: the Wither sometimes fails to spawn, or spawns incorrectly, when small blocks sit in the area where its body should form. Vanilla spawn checks can be blocked by these obstructions, leaving you with a broken ritual instead of a boss.

This mod corrects that spawning logic so the Wither forms properly even with minor interference. At the same time, it stays fully compatible with the Wither Spawn Animation (WSA) mod, so the animated altar effects you already use still play as intended. You keep the visual build-up without the failed spawns.

Install it alongside WSA when you want reliable Wither summoning. No configuration is described; the fix applies automatically. If you have ever placed soul sand and skulls only to watch nothing happen, this mod targets exactly that failure.
