Mage Slayer DnD 5E Feat

Hello adventurers of all shapes and sizes! Welcome to my spellbook and thank you so much for checking out the 32nd episode of our dnd 5e feat list series. Today we’re going to be taking a look at mage killer or mage slayer rather pretty much mage killer though my goodness.

This one is designed for those heroes out there who have for one trematic reason or another a burning desire in their soles, in their hearts or lowing to rather to destroy all that has to do with live. This interesting and flavorful feat is found in the players handbook with all that out of the way let’s take a look at its description. In any case you can check out sentinel 5e too.


Something worth noting there’s no prerequisite meaning anyone of any skill set, expertise level or can use it just fine and it reads as followed:

Being a mage slayer dnd 5e feat you have had practice of some techniques in the melee combat which are against to the spellcasters, and you can gain the following benefits too.

  • Whenever a creature which is within 5ft of you can casts a spell, you can also use your reaction for making a melee weapon attack which is against to the that creature.
  • Also when you do damage to a creature which is concentrating on the spell, where a creature has disadvantage on a saving throw and also it makes to maintain its concentration.
  • You have an advantage on the saving throws which are against to the spells cast by a creature within 5 feet of you.

A decent amount to unpack there. Let’s take a look at the walkthrough to really get to the core of the feat and its mechanics.


So a lot of attach the fairly self explanatory here. When they cast the spell within 5 feet of you regardless of what that spell is you can make a pseudo attack of opportunity against them. You can use your reaction to make a melee attack. Really useful stuff there. You may also like to read 5e magic initiate.

When you do strike them..should they happen the concentrating on the spell, they’ve disadvantage on those constitution saves. Which is super useful. Especially through using some kind of mine dominating ability or spell or even a particularly nasty damaging when something like flaming sphere at higher level. That could be very useful. Are you waiting for mobile feat!

The third reporting there you’ve advantage on the saving throws when the spells are cast gesture within the 5ft range. Which is kind of underwhelming honestly, i wish it was worded something to the effect of your advantage on saving throws against spells, so as long as your an initiative against the spellcaster.

I think that’d be a good one of do it. But i know my wizards can’t work with as any other stuff. Let’s get to my personal thoughts on it. Would you like to read misty step 5e now!


I really like this one in terms of how clean pack to characters backstory and kind of complimented. I really like how cool also kind of lot of peoples play styles. In terms of who benefit most from it….You know i wanna say rogues in all honestly. Think rogue will make fine use of it, thing with that i wish warlocks they could probably make they get hexblade warlock for example things they could probably would as well. You can also get to know about observant 5e.

Reason being they both have the capability to kind of sneak to that backline in most of the casters usually are. They are also quite good a melee attacks so they don’t really have to worry about that and the ability to strike one down as essentially a reaction is super beneficial because both the hexblade warlock and most rogues if done properly can be shot a very substantial trunket downage in one melee attack.


That being said, if you think of any classes that would work particularly well with please let me know down beneath in the comments. As well as if you have any cool stories or build concepts regarding mage slayer, i really like to read them and i know everyone else checking this article does as well. That being said guys, have a great day and as always happy adventuring.
