EffectImmunity
Tracking Issue: #1575
This is one of the three functions required to enable boolean management for whether or not X2Effects will be allowed to be applied to a unit. This enables various functionality that was previously heavily limited by damage typing. An example use case: We do not want to X2Effect_MindControl to be allowed to be applied to a unit, but we want to allow other Mental-typed effects to effect this unit. This would enable that. Alternative use case example: We want to block a Chosen from being able to be Frozen, but do not want to block damage from a weapon that is damage typed as Frost This also provides a solution should we want to block an effect that has no damage typing. And many more.
