Realpower
by kazut0
Realpower, a Fabric client mod, shows the actual damage a held weapon deals to an opponent wearing a given armor set, directly in item tooltips.
What it does
When a player holds a sword, axe or pickaxe, the tooltip shows the real damage that weapon would deal after the target's armor is taken into account. The calculation covers base attack damage, the attribute modifiers the item carries, the extra damage each enchantment level adds, and status effects such as Strength and Weakness. Armor is simulated per material, so leather, iron, diamond, netherite and toughness penetration each change the reduction shown.
The mod runs only on the client, so a player can install it on a single-player world or a multiplayer client with no change on the server. Customization is handled by Mod Menu and YetAnotherConfigLib (YACL) v3, which are both required. The file targets 1.21.8, and the mod is released under All rights reserved, so it is not open source.
Key features
Actual damage in tooltips
Tooltips show the damage a held weapon would deal after armor reduction, rather than only the raw attack value.
Armor set simulation
Each armor material and its toughness and penetration values are modeled, so the displayed result reflects a specific opponent's gear.
Enchantment and effect math
Protection enchantments, per-level damage bonuses and Strength or Weakness effects are included in the displayed figure.
Configurable options
Display options are set through a YACL v3 screen reachable from Mod Menu.

Use cases
Who it’s for: The mod suits players who want to understand combat numbers in single-player or multiplayer, and who are willing to install Mod Menu and YetAnotherConfigLib alongside it. It is a client-side tool, so server owners do not need to add it.
How it compares
PvPHitCounter is a Fabric client mod for 1.21.11, released under the Creative Commons Attribution Non Commercial No Derivatives 4.0 license, so it is not open source; it counts hits rather than showing damage figures. Sharper Tooltips is a Fabric client mod for 1.21 – 1.21.10 under the MIT License, which makes it open source, and it changes how tooltips are laid out rather than calculating damage. Enchanting Tooltip is a Fabric client mod for 1.21.1 – 1.21.11 under All rights reserved, so it is not open source, and it shows enchantment details in the tooltip.
