Zoe builds generated from the raw maths of League of Legends. Using combinational optimization techniques such as multi-objective optimization and genetic algorithms. The optimal builds can be found via pure computational brute force. Customization is supported, you can override all items and all runes and the rest of the build will adapt to handle your choices. You can optimize Zoe for different roles and different ratios of Damage, Ability Haste, Effective HP, etc. Best of all you can find the optimal build rather than just guessing blindly.
