I couldn’t find a dedicated c/unearthedarcana so I’m posting here. I’ve been creating a handful of homebrew spells to fit characters I’m playing. For this one I wanted to make a spell for my lighting storm-themed gish character that would also be a nice capstone spell for an Eldritch Knight in general. While there are some similar-ish spells I’m basing it off of, I wanted some feedback if it’s balanced based on the damage numbers and amount of benefits for its spell level.

Personal Lightning
4th-level evocation
Casting Time: 1 bonus action
Range: Self
Components: V, S
Duration: Concentration, up to 10 minutes

You channel the energy of a fierce lightning storm within your body. You gain the following benefits until the spell ends:

  • Attacks you make deal an extra 1d6 lightning damage on a hit.
  • Your speed increases by 20 feet.
  • Your movement doesn’t provoke opportunity attacks.
  • Your jump distance is tripled.

As an action on your turn, you can dismiss this spell and cause a blast of electricity to erupt from you. Each creature within 20 feet of you must make a Constitution saving throw. A creature takes 3d6 lighting damage and 2d6 thunder damage on a failed save, or half as much damage on a successful one.

At Higher Levels: When you cast this spell using a spell slot of 5th level or higher, the thunder damage dealt by the blast increases by 1d6 for each slot level above 5th. Using a spell slot of 6th level or higher also causes you to gain a fly speed of 50 feet until the spell ends.


Edit based on feedback: I’m getting a variety of responses, so I’m figuring out what exactly needs to be targeted for adjustment here. The blast option seems to be considered a bit strong since it’s an additional mode to the other benefits. I can shrink the range and drop the damage a little. I don’t want to nerf it too much though because it’s still costing an action. Maybe drop it down to 15 foot radius and, what, 3 or 4 damage dice?

In terms of the main mode of the spell, I want the spell to compare fairly overall with guardian of nature which is the same level. Guardian has two different modes that both give advantage on (pretty much) all of your attacks; with that in mind I’m considering if it’s fair to up the damage dice from my spell to 1d8 per hit. Would that be fair, or am I underrating the other benefits of my spell here?

      I’m not sure I’m seeing how it amounts to action surge-y? The thing about the blast is that it costs your action on that turn, so if I make it too weak then it won’t be worthwhile ever using it vs just keeping the spell up and continuing to attack with it or dropping the spell normally and doing something else with your action.

      Holy weapon’s blast, which was the inspiration, is substantially more impactful: more damage (slightly), bigger area, and it can even inflict blinded, plus it’s triggered as a bonus action rather than an action. Of course my spell can’t be as good since it’s a level lower, but I do think the comparison is more than fair even given that, between the blast effects at least.

      I guess, do you think I’m underrating how good the movement effect is? I’m trying to make it comparable to guardian of nature which is also 4th level and can add 1d6 damage per hit, plus it gives advantage on your attacks. Since advantage is really strong I don’t wanna just add that to my spell instead but I do want the other effects to end up being comparable. I did originally consider just giving disadvantage on opportunity attacks rather than ignoring them completely, but I figured if zephyr strike and Ashardalon’s stride could ignore them with lower level slots it should be ok.

      Thanks for your feedback, I do appreciate it!

          I don’t want the AoE to take away too much from the rest of the spell, it’s like 50% there for the flavor/coolness effect anyway. My experience with taking holy weapon on my Cleric is that you’ll often end up dropping the spell from taking damage or you’ll hold off using the blast because you wanna keep swinging, so you end up not using the blast anyway. So I don’t want the blast to drag down the power of the rest of the spell. Seems like there’s a fine line between making it overpowered and making it unusable here.

          You have a good point comparing it to ice storm, which only does a little more damage than the blast. Though on the other hand ice storm kinda sucks, doesn’t it?

          I guess speed buff + op-attack immunity does make you pretty untouchable to melee from most humanoids, that is pretty good. I do want it to be better than haste since it’s a level higher. If I nerf the AoE a bit do you think the rest is balanced overall?

              I’m probably gonna end up nerfing the blast at least a little so it feels a bit more fair overall, since a number of responses thought it was overturned. Probably take a damage die off and drop the range a little.

              The dual damage types is mostly flavor, I think thunder is a little better than lightning technically? but they’re pretty close, and I don’t think you’d cast this if you’re fighting something resistant to lightning anyway.

              With the main mode it seems like it’s in a fair spot, then? Better than haste, seems fair compared to guardian of nature? Part of the balancing is also that it’s self-buff only, so unlike haste and holy weapon you can’t have the 7th level Wizard give it to the Fighter.
