No, it does not (unless it requires concentration). The Mage Slayer feat lets you make a melee attack against a triggering creature.
Can a ranger attack twice?
Extra Attack is gained by rangers at fifth level, and simply put, enables them to attack twice in a single round, rather than just once. This talent can be used once per combat round, and can be stacked with any other spells or abilities that otherwise allow your ranger to attack more than once.
When does a Mage Slayer use their reaction?
With mage slayer, if they cast the spell at disadvantage or with the melee spell attack, then you get your “When a creature within 5 feet of you casts a spell, you can use your reaction to make a melee weapon attack against that creature” portion of mage slayer .
What’s the difference between Mage Slayer and Misty step?
Also it’s Duration is Instantaneous, which means it happens the moment the spell is cast, there is no lingering or lasting effect which takes a period of time to fully complete the spell. I would rule that, while Mage Slayer would grant a Reaction to Attack the caster, there would be nothing to strike as they’re already a “silvery mist”.
What happens when Misty step finishes her spell?
When misty step finishes your target is no longer there and so you do not get an attack using your reaction from mage slayer since you no longer have a valid target. There are no rules in D&D 5e for interrupting a spell while it is being cast EXCEPT for counterspell.
Is the Mage Slayer feet useful in melee?
So realistically the Mage Slayer Feet isnt super useful. It depends on how you want to play it. If you are playing a mage killer, you will want to close as often as possible, particularly if you’re predominately a melee character. In melee, your superior AC and attack skills give you an advantage over many spellcasters.
