I was thinking of a new character and had a question about how this would work. You are a Echo Knight (Level 3+) Multiclassed with a Oath of Vengeance Paladin (Level 7+) who has the Tunnel Fighter fighting style (from this UA) and has used their bonus action to activate it on your turn. You and your Echo stand within 5 feet of a creature and it provokes an opportunity attack.
- Would both you and your Echo get an opportunity attack since your reaction isn't used?
- Could you then move up to the enemy who ran away getting within melee reach again?
- Could your Echo do likewise and move up with you within melee reach of the fleeing creature?
- Would you then both get to make an opportunity attack again if it leaves your reach (or just you if number 3 is not possible)?
I think you can't do this because you have to use your reaction the first time to move up to the creature. Could you repeat this again moving into the creatures melee reach?
'Tunnel Fighter (UA). As a bonus action, you can enter a defensive stance that lasts until the start of your next turn. While in your defensive stance, you can make opportunity attacks without using your reaction, and you can use your reaction to make a melee attack against a creature that moves more than 5 feet while within your reach.'
'Relentless Avenger. By 7th level, your supernatural focus helps you close off a foe's retreat. When you hit a creature with an opportunity attack, you can move up to half your speed immediately after the attack and as part of the same reaction. This movement doesn't provoke opportunity attacks.'
'Manifest Echo. When a creature that you can see within 5 feet of your echo moves at least 5 feet away from it, you can use your reaction to make an opportunity attack against that creature as if you were in the echo's space.'
