# Hungerless casting
Hungerless casting or reduced-hunger casting offer reductions in (or elimination of) the nutrition penalty incurred by spellcasting. Both are granted automatically and exclusively to high-intelligence wizards:[1]

Intelligence

Reduction

17 or more

No hunger penalty

16

25% hunger penalty

15

50% hunger penalty

14 or below or nonwizard

100% hunger penalty

Hungerless casting is very useful, especially when attempting the foodless conduct. The unreduced nutrition penalty for each spell level, with and without the Amulet of Yendor, follows:

Spell level

Normal hunger

Min with Amulet

Max with Amulet

1

10

12

30

2

20

22

60

3

30

32

90

4

40

42

120

5

50

52

150

6

60

62

180

7

70

72

210

Casting the detect food spell never incurs a hunger penalty. Also, if casting a spell would put you at three or less nutrition, your nutrition is set instead to three. Hunger cost is rounded down: for example, casting a level 1 spell with 16 intelligence costs only 2 nutrition.[2]

SLASH'EM
In SLASH'EM, as in Vanilla, only wizards get hungerless casting: the new magic-specializing roles, flame mages, ice mages, and necromancers, do not.[3]
