Add Pre-defined Effect that can give Advantage to Class Abilities

[Delgored]

Hi,

Can you please add Advantage to Class Abilities and Spells if you can? Checkbox?

This would allow the talents for advantage on spells and elixirs to be added.

As always, Thanks,

It's already possible to give advantage to spells via the built-in spellAdvantage pre-defined effect.

It would be possible to extend this to Class abilities as well though.

Pushing this back until we do #915
