Caveats

This is not a simulation tool!!! Use a simulator to optimize your character for fixed, full-fledged fights.
Spells are typically computed on a per ability basis using probabilistic expectation but may take into account averages of various effects that are reasonable enough (e.g. Nature's Grace, Illumination, Clearcast talents etc) according to your configuration.

Troubleshooting

If you have issues or suggestions, the best way would be through Github issues or Discord.

Localization

The addon is functionally localization agnostic. Localization of UI strings is also supported, can be turned on in settings but only has some placeholders from automated translations.

Support
