Irons Spell N FTB Teams
by HenryCROSS
Irons Spell N FTB Teams is a NeoForge addon that makes Iron's Spells n Spellbooks summons respect FTB Teams when they pick attack targets.
What it does
Summons created by Iron's Spells n Spellbooks spells, such as skeletons, zombies, vexes and polar bears, check team membership before choosing a target. A summon owned by a player will not attack that player's teammates or their summons, even when those teammates are players themselves. Teammates can still damage each other directly, because friendly fire stays under the vanilla scoreboard team settings.
The addon is a small patch with no new items, blocks or spells. It applies a minimal Mixin to the summon targeting logic. Both the server and every player need it, so it has to be installed on both sides. Mobs summoned by bosses, such as the Necromancer or the Fire Boss, are not affected, since only player-owned summons are considered. A single config toggle enables or disables the behavior, and turning it off requires no uninstall.
Iron's Spells 'n Spellbooks is a required dependency, so the addon fails to load without it. The addon also needs GeckoLib, Curios, Player Animator, Iron's Lib, Architectury and FTB Library installed. The addon is published for NeoForge 1.21.1 only and is open source under the GNU General Public License v3.0 or later. Its code was generated with AI assistance under human direction.
Key features
Team-aware summon targeting
Player-owned summons skip members of their owner's FTB team and the summons those members control.
Friendly fire unchanged
Direct damage between teammates follows the vanilla scoreboard team settings, so it is not blocked by the addon.
Boss summons excluded
Mobs summoned by bosses keep their original targeting, since only summons owned by players are changed.
Single config toggle
One config option turns the team targeting on or off, and turning it off does not require an uninstall.

What the author says
A lightweight bridge / addon mod: makes Iron's Spells 'n Spellbooks spell summons (skeletons, zombies, vexes, polar bears, etc.) respect FTB Teams allegiance when picking attack targets. Within the same FTB team, players — and their summons — will never be targeted by each other's summons, even if the players can…
