How to Use

Here's a guide to using LoL Build Sim.

1. Champion Selection

There are champion selection areas on the left (Blue side) and right (Red side) of the screen. You can type a champion name in the search bar or use role filters to quickly find your champion. When selected, the champion's base stats are automatically loaded. Use the level slider to adjust between levels 1-18, and stats will update instantly.

2. Item Selection

The item shop allows you to select up to 6 items. Filter by category (Attack, Magic, Defense, Boots, etc.) or search by name. When an item is selected, its stat bonuses are immediately reflected in calculations. Click an item slot to select an item, and click again to remove it.

3. Rune Configuration

In the rune section, select your primary and secondary paths and configure runes for each slot. Stat shards are also selectable, and all rune effects are automatically reflected in stat calculations. The rune section is collapsible to save space when not in use.

4. Combo Setup

When a champion is selected, a skill combo bar appears. Set the number of uses for each skill (Q/W/E/R) and auto attacks (AA) to calculate full combo damage. You can also toggle summoner spells and item active effects. Passive proc counts can be adjusted as well.

5. Reading Damage Results

Damage calculation results are displayed in the center of the screen. You can check auto attack damage, individual skill damage, full combo damage, DPS (damage per second), and kill potential via the HP bar. Damage is shown bidirectionally (Blue to Red and Red to Blue) so you can intuitively understand 1v1 outcomes.
