Two unrelated things that became related in my brain:
- It would be reasonable to model Captain America’s superpowers (from certain eras and writers) as just “human max attributes.” In D&D/Pathfinder, that’s 18s (or maybe 20s) in all six ability scores.
- While I have my misgivings about the fungibility of the race features in the Advanced Race Guide*, I couldn’t help but notice that the point scales involved in race building seemed fairly similar to the points used to buy ability scores. In particular, I wondered if it would be fair to do something like allow a player to be an aasimar (a 15 point race) in a party of players handbook races (9-10 point races) in exchange for the aasimar PC having 5 fewer points for ability scores.
Those ideas gelling in my head, I did do some additional math and found out that, indeed, the race point balancing is relatively close to ability point balancing. To wit, if you made a PC with all 18s it would cost around 90 ability or race points (not counting the first 15 points that normal characters get); for race points, it’s using the +2 ability score bonus with no strings that increases in cost for each cumulative +2. The price is likewise similar (around 130) for all 20s. Since the math is close enough, let’s move on to the system below.
* In that my intuition and experience is that it leads to players ditching rarely used but interesting features for boring features they think they’ll use more
You can turn Pathfinder into a supers system by just giving out bonus points that can be spent on ability scores or racial features. A character of around Captain America’s power level gets 100 or so points. Notably, these characters will be hella awesome for first level characters, but scale normally through character level (and mythic tiers, if you’re feeling particularly gonzo).
Character points can be spent in three major ways: enhanced ability scores, racial features, or spell-like abilities.
While the normal point buy rules stop players from buying over 18, it’s easy to extend the costs indefinitely upward: the cost for each ability score increase is equal to the modifier for that score (e.g., it costs 5 points beyond the cost of 19 to get to 20, because 20 grants +5).
The extended chart is below:
|Score||Total CP Cost||Score||Total CP Cost|
So someone that had 100 points and went all in on an ability score could start with a 30 or better.
Most of the racial features from creating new races (p. 215 of the ARG or here) are probably viable for building heroic abilities. Hell, you need a pile of superhero points to afford to be a robot (sorry, “construct”).
Specifically, leave out the racial features that modify ability scores (use the point costs above) or grant one-off spell-like abilities (see below). Otherwise, anything the GM and player agree works for the character’s power concept should be fair game for the prices listed.
The real bread-and-butter of making supers is the freedom to pick spells to use as spell-like abilities. Want to be a blaster? You can do worse than Scorching Ray. A teleporter? Dimension Door.
The costs in the ARG seem relatively cheap for this purpose, though: it makes more sense to sell players a second level spell per day for 2 points when they’re going to have less than a dozen points, but that’s a LOT of scorching rays if you have 100 points to spend.
So I suggest for this purpose you cost spell-likes as their level squared. So:
|Spell Level||CP Cost|
You can also work out with the player how many uses are required for something to become an At Will spell-like ability, or an always-on supernatural ability. For attacks and other primarily-in-combat powers, I’d work out how many times I genuinely expect the player to use it in a day, and make it At Will once that many uses are purchased. For utility abilities, particularly long-duration ones, it may only take a few per day to become a self-only, always-on supernatural ability. Healing and other things that become really good out of combat with unlimited time should probably never become At Will.
Like racial spell likes, the caster level for these abilities is equal to total character level/hit dice, and the save DC is equal to 10 + spell level + the most relevant ability score modifier (but don’t let the player browbeat you into setting the save DC to the ability score he’s raised to a crazy high level if that doesn’t actually make sense).
And with all of that, you’ve hacked in superheroes. Either turn them loose on the normal fantasy classes and setting, or strip down the core classes to run something more traditional for supers.
