Terraria-Fied Armor Defense

Under the vanilla system, armor takes a fixed share of damage. This mod changes that rule: instead of a flat damage reduction per armor point, the armor value reduces the incoming damage by a set amount. In the author's example, 10 armor against a 15 damage hit leaves 5 damage taken, so a strong armor value can cut a hit much more sharply than before. The override is optional and can be turned on or off in the mod's settings.

Other parts of the mod are built as stackable defense systems that add on top of the base rule without changing the armor items themselves. Damage that bypasses armor and removes health directly, such as percentage-based damage, is handled separately and is not reduced by armor. Enchantments on armor still work as usual and add their own damage reduction. A minimum of 0.1 to 1 damage is kept for each hit, so armor never reduces damage to zero.

The mod is built for Forge 1.20.1 and runs on client and server, so the server and every player need it. It depends on no other catalog mod for its core behavior, though the author notes some optional dependants for extra content. The license is All rights reserved, which means the code is not open source.
