Kage’s suggestion for Link’s Action Skill:
A quick dash and heavy-damaging melee blows. Locks onto the nearest enemy. Essentially the slashes form a very familiar shape.
With the help of one of the tier three skills [likely in the skill tree dedicated to melee], you can max this out to being able to strike three targets in one dash.
The final blow deals some amount of bonus Explosive damage.
Still need a name for the Action Skill, though. Suggestions?
