Kiss of Mephistopheles Invocation (UA)

Hello warlocks of all shapes and sizes! Welcome to my spellbook and thank you so much for checking out the 9th episode of our warlock eldritch invocations unearthed arcana series. These are all play testable so they’re not canon or true to the actual 5E material. So just get your DMs permission before you use them.

In any case today we’re talking about a particularly strong one a little bit too strong in my opinion. Today we’re going to be taking a look at kiss of mephistopheles dnd this one’s particularly interesting in a couple of ways, from the way it’s described to the mechanics it uses and i’ll kind of get into why that is in a little bit. That being said, let’s take a look at the mechanics.

What makes this so strange is there’s not one, not two but three prerequisites. You have to be at least 5th level that is five levels of warlock by the way not five total character levels. You have to picked the fiend as your patron and you have to be like as the eldritch blast cantrip. So pretty self-explanatory there, the description reads as followed.

You can channel the fires of Mephistopheles through your eldritch blast. When you hit a creature with that cantrip, you can cast fireball as a bonus action using a warlock spell slot. However, the spell must be centered on a creature you hit with eldritch blast.

So pretty cool! Makes sense, not really a whole ton to break down. But let’s kind of simplify it a little bit in the overview section and explain how i would present this to my DM. Also read this can warlocks get polymorph?


So essentially when you hit a creature with eldritch blast, you can cast fireball as a bonus action using a spell slot. The blast much be centered on a creature hit by eldritch blast.

So what i don’t like about this is is way too strong i mean the ability to cast fireball 5e as a bonus action in general is potentially game breaking and when you combine that with the ludicrous damage eldritch blast can put out this could one-shot a lot of groups, a lot of parties for sure. You can also read can a paladin lay on hands himself 5e

How i would work it so, it would be allowed is i would just make it so warlock 5e could cast fireball. That’s probably the best way i could do it, not as a bonus action or anything just make a cast fireball that’s probably the best way to do it.

Yeah that’s probably the other way you could really go about it now that i’m thinking about it. You could try and make it where they could forego all of their eldritch blasts as an attempt to make a fireball using a spell slot they can lead to that one once per long rest but i think just giving them fireball works just fine.

In any case that’s my thoughts on it, if you have any thoughts, opinions, questions or anything you’d like to add please do so down beneath in the comment section. We really enjoy chatting with you guys and i really do appreciate all the support. That being said, i hope you all have a wonderful day and as always happy casting.
