DiceSum is your dedicated math wizard, simplifying complex TTRPG calculations so you can spend less time tapping and more time living in your game.

### 🚀 Master Your Calculations

We go far beyond standard `1d20` rolls. Simply input your equation, watch the magic happen, and instantly get the accurate result.

**✨ Key Features:**

* **Advanced Formulas:** Use full standard notation: `(2d3d(4d10 x 2) + 1) / 3`.
* **D&D Ready:** Effortlessly handle Advantage (`a`) and Disadvantage (`d`) on any roll.
* **Step-by-Step Breakdown:** Never wonder how your total was reached. DiceSum shows the exact path from dice roll to final sum.
* **Action Log:** Save, edit, and categorize your "Actions" (Spells, Attacks, Skill Checks) for instant access mid-session.
* **Full Arithmetic:** Supports addition (`+`), subtraction (`-`), multiplication (`*`), and division (`/`).

### 🎲 What Can You Roll? (Examples)

**Simple Rolls:**
* `2d6 + 5`

**Complex Formulas:**
* `2d20 + 5 - d4d6` (Roll 2d20, add 5, subtract the result of 4d6)

**High-Powered Checks:**
* `(1d20 + 2d(a 3d4)) * 3` (Roll 2d3d4 with Advantage, add 1d20, multiply by 3)
