Most Champions have one or more skill cards, denoted by the skill icon in the upper left corner of the card. Some skills affect specific targets, and have targeting icons like attacks.
When a player activates a Champion using a skill card, they resolve these steps in order:
1) Use as much of the card’s movement as you choose.
2) Choose if you will use the skill. If you choose not to, the activation ends immediately.
3) Declare target(s), if necessary.
4) Resolve the text box of the skill card.
