I was thinking of Opportunity Attacks, and how they are handled in other systems. That reminded me of an interesting little Feat in Pathfinder called Step Up, which allows you to pursue Opponents that attempt to escape your Reach.
I thought I’d try to make something similar in Open Legend and after bringing it up on the Discord server, I decided to go for something simple:
Cost: 1 Point
Prerequisites: Agility 4 or Might 4
Description: Enemies have a hard time taking their distance from you, whether that is because you’re particularly fast, have expert footwork or a quality that allows you to partly get teleported along.
Effect: Whenever an enemy moves out of your Reach, you may follow them up to half your Speed as a Minor Action that can be taken outside your Turn. This movement provokes Opportunity Attacks as normal.
With this, the Movement gained from Defend Interrupt Action loses some strength and normal movement and/or Evasive Footwok is less effective, though can still achieve the goal of leaving one’s Reach.
The movement would take place after an Attack and the enemy’s movement, so there’s no additional Opportunity Attack to be had, at least not how it is now.
Unless the enemy Defends against an Opportunity Attack, moves away, you Step Up, the enemy moves away again and you also have Battlefield Opportunist, that is.
Maybe there could be multiple Tiers to this Feat which allow for moving multiple times a Round, similar to how Battlefield Opportunist works. It shouldn’t work multiple times on the same movement though.
I changed “10 feet” to “half your Speed”, since part of the intent was to match with the movement gained from the Defend Interrupt Action. It seems I had misremembered that.
