[ISS DSB]Distant Shock Barrier
by LOAE_U987
[ISS DSB]Distant Shock Barrier is a NeoForge optimization mod for 1.21.1 that limits how far Iron's Spells spells can reach, so that oversized spell ranges stop causing performance problems.
What it does
The mod ties a spell's power to its distance: the farther a spell travels or its block range extends, the more destruction it causes at the cost of the caster's output, so very large ranges become expensive rather than free. Its main purpose is to solve the performance issues that excessively large spell ranges create on a server. The mod is released under the MIT License as open source, and its source code and issue tracker are public. Files exist for 1.21.1 only, with 1.0.0 as the current NeoForge build, published 2026-03-21. It runs client and server, so both the server and every player need it.
Key features
Distance-based spell cost
Spell power is linked to distance, so a longer reach carries a higher price in destruction and cost.
Block distance scaling
Block-range effects of spells scale with how far they travel, limiting the destruction they can cause at long range.
Iron's Spells addon support
The mod works as an addon to Iron's Spells 'n Spellbooks, targeting the lag that very large spell ranges produce.
