[SBM] Dual Wither
This minimalist mod significantly increases the challenge of summoning the Wither boss by creating an exact copy behind each player located near the original summoning location.
How the Enhancement Works
Every time the original wither boss appears, [SBM] Dual Wither automatically generates an identical boss behind all players within the effective radius. The new threat spawns at a distance of up to 15 blocks directly behind the character, with a vertical tolerance of ±2 blocks. If the system doesn't find a suitable placement location, the additional boss won't be created.
The mod's design includes intelligent error prevention mechanisms: it ignores Wither bosses that existed before the mod's installation, as well as those created anew after reloading the game world. The developers implemented specialized code to minimize false triggers from mob spawners, though rare exceptions may occur with certain modifications due to unconventional creature generation methods.
A significant advantage of this enhancement is its ability to function exclusively on the server side. Clients aren't required to install it for proper operation.
Source of Inspiration
The idea for creating the addon emerged completely spontaneously after a user's post on Twitter suggested an intriguing scenario: "what if when summoning a regular Wither, a second one appeared — right behind you?" This proposal seemed so unusual and captivating that the developers immediately proceeded to implement the concept.
