This is definitely more of a stream of consciousness post, I’m thinking through various principles for designing spells for my Artificer player. He’s the only guy in our group that’s attending school abroad, so I try to toss him extra goodies to entice him to show up for games. It works (about 50% of the time)! Jokes aside, he largely only fails to show up when he can’t. Anyways, those goodies take the form of crafting primarily. Whenever my player is away, he’s on the airship crafting firearms, potions, magical oddities, you name it. We ran into a bit of a problem though; he wanted a self-winding grappling hook. I’ve got a good grasp on the mechanical advancement of the world and how its limitations differ from those of real life (you can check this post for why firearms will never become widespread in my world). Long story short, it wasn’t gonna happen (not in the form he wanted at the very least).
Being the ever generous DM, I made him an offer; why not create a spell that did what he was looking for? He was an intelligence based caster, after all. This excited him a great deal, and after a short delay, I set off to work!
Not bad for a first draft, right? It’s even cooler for the artificer, because he gets an ability that let’s him place spells in items! He can literally place this spell that uses a grappling hook as a material component into the grappling hook and hand it off to another character. There’s a bit of wording to fix, I need to say “alternatively, you can swing up to 60 feet away, provided the anchor point is at least 20 feet above you” or something.
You get the idea, though! The moment this concept played itself out it my mind, I started thinking of other artificer spells. It’s such a unique class, of course it would benefit from unique spells! What would they look like?
The Artificer’s ability to place spells in an object is a factor in any spell I design for them. Material components normally are not important beyond a gold cost. The Artificer could of course cast spells into unrelated objects. It’s incentive enough to make spells that focus on altering equipment for me, however. I’m attracted to that variety of narrative/mechanic synergy.
Next is action economy. The Artificer has plenty of things to do with his action already, mostly shooting things with a firearm. As such, anything that isn’t a bonus action spell should probably have some sort of significant effect. I understand that’s horribly unspecific, so I’ll try to drill it down in a sentence or two. Bringing a party member back from the brink of death with a cure wounds, forcing multiple creatures prone with grease, etc. Something that cures or deals a status effect is “significant”, or perhaps is better stated as “changes the conditions of the battlefield”. Spells shouldn’t simply deal damage, they should augment damage. Anything worth casting with his action at such a low level spell would not be balanced in the least, the dude has 1/3rd casting progression. No, the spells need to impact the battlefield in some manner other than damage. Damage is a nice rider if the spell takes an action, but I should look to balance bonus action spells.
Finally, we have spell levels to watch out for. Anything I make for the Artificer can be picked up by the Bard at level 10 with magical secrets, but I’m not terribly worried about that. My primary concern is multiclassing. Since I’m as much of a power gamer as power gamers can be and an avid fan of multiclassing, I usually know what to watch out for. The more the spell is meant to synergize with the class I’m designing it for, and the greater investment a multiclasser has to make to get that “prize spell”, the less I need to worry about it. Things shouldn’t be so far down the line that they can’t access it, on the contrary. I want players to actually feel special with the artificer. Is a 3 level dip enough of a cost to get a new take on misty step, or cast a special spell on a grappling hook? I think so.
Let’s look at another spell I designed somewhat spontaneously.
By the time the artificer gets this, he’s at least 13 level. It fits with his class, it’s an excellent secondary damage boost (6d6 with the thunder monger from his class, 2d8 from the spell, all to 2 targets, one of which doesn’t require a roll to hit). It’s far enough in that I don’t have to worry about any nasty “I dip in, now I’m OP” multiclassing (though dipping out of the class could make for some interesting combinations). It fits his theme (spell requires a firearm, he’s all about mechanical weapons, can literally implant the spell in the gun for later use, etc). I’d say it fits my principles!
I already had some additional ideas for spells (which will sadly stay out of view until I release a supplement focused on them)!
