The Lipimancer: Update

One of my players is playing a Lipimancer! And he is rocking it! So now I have to take my half baked idea and make it into a usable 5e sub-class.

Some quickly obvious problems arise from the original post:

• It implies an infinite number of spells per day assuming you can find enough food
• Having spells cost calories means that I have to figure out a way to equate relative cost of different spell levels

The simple solution is to use an already built in mechanic of the sorcerer class, sorcerer points, and keeping the spell casting system intact.

Invest in suspenders, you'll need them

The Lipimancer:

Regaining Spell Slots: When you take a long rest you regain all of your spell slots but it consumes all of your stored calories, AND unless you have full calories stored you only regain half of the number of spell slots per spell level, rounding down.

So a 4th level Lipimancer goes to sleep with only 10,000 stored calories she wakes up hungry (no calories stored) and with only 2 1st level spell slots and 1 2nd spell slot restored. Lipimancers are cranky in the morning if they are hungry.

Wellspring of Vitality: At 2nd level you learn how to tap into your bodies stored energies to augment your casting. 4,000 calories are equal to 1 sorcerer point, and unlike sorcery points you do not regain all of your calories at the end of a long rest, you have to eat to get them back. You can never have more calories stored than your current calorie cap (see table below).

Let the Fat Flow: You can translate your stored calories into magical energy and vice versa, either by spending calories to get spell slots refreshed or spending spell slots for more calories (but never more than your cap!), both are bonus actions. You cannot regain spell slots greater than 5th level using this ability.

Some Tables:

Level	Sorcery Points	Calorie Equvilent
1st	-	4,000
2nd	2	8,000
3rd	3	12,000
4th	4	16,000
5th	5	20,000
6th	6	24,000
7th	7	28,000
8th	8	32,000
9th	9	36,000
10th	10	40,000
11th	11	44,000
12th	12	48,000
13th	13	52,000
14th	14	56,000
15th	15	60,000
16th	16	64,000
17th	17	68,000
18th	18	72,000
19th	19	76,000
20th	20	80,000

Spell Slot Level Regained	Sorcery Point Cost	Calorie Cost
1st	2	8,000
2nd	3	12,000
3rd	5	20,000
4th	6	24,000
5th	7	28,000

(I like this because it builds in a cap to the number of calories the Lipimancer has stored away to use for magic but leaves the spell casting system intact so that they can use them seamlessly with the sorcerer's class abilities, and I don't have to mess with fudged spell level equivalence)

Metamagic: At 3rd level you gain the Metamagic ability, as described in the PHB, except that you expend calories instead of sorcery points.

Spontaneous Lipid-Generation: At 20th level you regain 16,000 calories just by taking a light nap (a short rest). You must be asleep for this to work.

Suddenly giant chickens become the most desirable enemy to hunt.

Okay great, we've tweaked the sorcerer class enough to work as a Lipimancer, now lets make their sub-class abilities:

Way of the Fat Mage: At 1st level you gain access to your calorie pool, but only for use in determining spell slot replenishment. You also get all of the tweaks to the sorcerer class as described above. In addition you  the following spells to your learn able spell list:

Spell Level	Spell
Cantrip	Consume
1st	Emesis
2nd	Swallow Whole
3rd	Vortex of Excess
4th	Dimension of Flesh

Over Burn: At 6th level you can choose to spend more calories than you have stored, sending you into calorie debt. When you over draw this way you must make a DC 12+(1 per 4,000 calories expend bellow 0) Constitution save or fall unconscious and takes 1d6 Con damage. You can only be awoken if force fed enough food to get you back to positive calories, but the Con damage remains until magically restored or taking a week of downtime recovery and eating your full calories every day per point of Con damage.

So a 6th level Lipimancer has only 4,000 calories stored, but he really needs to cast one more 1st level spell. He expends the calories (8,000) to get the spell slot as a bonus action and then he rolls a DC 13 Constitution save. If he passes she acts normally, if she fails she falls into a low-energy coma state and take 1d6 Con damage. He can continue to over draw this way down to -24,000 calories (bottom cap mirrors top cap), at which point he falls into the coma state regardless, but she only takes Con damage if she fails her save.

14th Level: Leaving for player and I to work out.

18th Level:Leaving for player and I to work out.
