Custom Card Effects

If you made it to this page congrats. You can skip this section for now while I think of a good novel custom card effect that the base game doesn't provide. Feel free to hop on discord and I can explain the steps.

However the thing with a Custom Card Effect is you should only write one if it is absolutely necessary. You should never need to write a custom effect that damages units, or heal units. CardEffectDamage and CardEffectHeal with a custom card trait will handle many, many cases. And if you have a novel method to calculate how much damage to deal then you would just write a Custom Tracked Value for it to use with CardTraitScalingAddDamage. The reason being is because the shop upgrades look for specific card effects by their name, adding new card effects means that each exclusion filter needs to be updated, and can result in mods shop upgrades not working with your specific effect.

So if you have a novel idea, ask, but I bet we can find a way to do this with the tools available in the base game.
