You may not skip the following abilities/effects:

* Negative effects: Effects that when performed will (not may) reduce hit points, lose cards, or apply a negative condition to yourself or an ally .

* Stand alone infusions (i.e. not attached to a specific ability). Note that infusions gained from modifier cards are considered attached to the attack so they can be skipped. Also, for characters, at least one ability on the action must be performed in order to gain the standalone Infusion. This is not true for monsters, they cannot skip abilities and do perform their infusion even if they can't perform another ability during their action.

* XP granting abilities, whether standalone or attached to another ability. If standalone, at least one ability on the action must be performed in order to gain the XP.

* +/- X ability adjustments from modifier cards.

* Individual targets of an AoE attack - if you do the attack, all eligible targets in the area must be attacked. Note that Add Target and Target X are not AoE abilities and can be skipped. For Target X, you may attack less than X targets.

* Charges and their effects of a multi-use item or ability if the triggering conditions have been met

You may skip any other ability or effect, including some or all effects attached to an attack but you must chose to do so BEFORE drawing an attack modifier card.
