+# D4 Tools
+
+Lightweight, clutter-free, web-based, open-source tools for Diablo 4 to calculate stats like damage or defense.
+
+### Common features
+
+- Super lightweight design with no external dependencies (<100kb total size)
+- Store calculators in your browser cache (localStorage) and export as JSON files
+- Open multiple calculators side by side
+- Disable properties temporarily (to quickly see changes)
+- Drag & drop sorting
+- Responsive design for large (desktop) and small (mobile) screens
+- Light/dark mode
+
+## Damage Calculator
+
+The D4 Damage Calculator is a useful tool to assess your build, evaluate your damage and find ways to optimize it.  
+It **combines all D4 damage buckets** like weapon damage, main stat (str, dex, int, wil), additive damage ([+]%), multiplicative damage ([x]%) and more to **calculate your total damage** per hit.
+In addition it supports **critical hit**, **vulnerable** effect and **overpower** damage (including HP and fortify).
+To compare different variants of your build and test changes you can **open multiple calculators** next to each other and easily **store, load and export the data** (as JSON files).  
+
+URL: https://bytemind-de.github.io/apps/d4/damage.html  
+
+**Typical questions** to answer with this calculator:
+- _What is the total damage per hit I can expect when using skill A with a fully charged aspect B and overpower + critical hit?_
+- _What is better with my current gear, +50% critical damage or 80 more strength?_
+
+### Ideas to improve it
+
+- Implement weapon speed and DPS
+- Add predefined properties (skills, passives, glyphs, paragon nodes etc.) for the user to select
+- Read the data from your actual account via some Blizzard API (d4armory seems to be able to do it, but how???)
+
+### Known bugs / quirks
+
+- To get correct values we need to apply an approx. 66% global damage reduction for monsters. This value seems to be independent of world tier, but I haven't really tested it with low-level characters.

+
+## Defense Calculator
+
+The D4 Defense Calculator is a tool to evaluate your defense and determine your **"effective" life against certain attacks**.
+It will also **calculate your armor required to reach the 85% DR cap** against a specific monster level.  
+
+URL: https://bytemind-de.github.io/apps/d4/defense.html  
+
+**Typical questions** to answer with this calculator:
+- _What is my 'effective' life when defending vs bleeding enemies that do physical damage in close range?_
+- _What is better with my current gear, 4% more life from a ruby or 3% damage reduction from a sapphire?_
+
+### Ideas to improve it
+
+- Add damage groups to be able to calculate defense for multiple attack types at the same time (close, distant, fire, poison, etc.)
+- Simplify handling of rubies and paragon nodes (% life), so you don't have to enter every single one
+
+### Known bugs / quirks
+
+- There might be slight rounding errors in the result, because the game often doesn't give you the full values (e.g. Doombringer is actually 41.44% life not 41.4% etc.)
+
+### Credits
+
+- Armor cap calculation is based on [SkyLineOW's findings](https://www.reddit.com/r/Diablo/comments/152gd9u/i_mostly_cracked_the_d4_armor_formula_and_made_a/)
