FIQHack/Monster spellcasting

In FIQHack, instead of having their own dedicated spellcast list, monster spellcasting instead use the same spellcasting rules as the player. Monsters have energy (Pw), just like players do. They gain or lose Pw as they level up, in an approximation of the player formula:

• Start with a minimum: 0 for dwarves, 2 for nymphs, humans, gnomes or dedicated casters, 3 for elves and dragons, 1 for everyone else
• Add a random number between 0 and Wisdom/2 + 1 (+ 1 for dedicated casters)
  • Base wisdom before helm of brilliance is 20 for Wizard of Yendor, 18 for dedicated casters, 11 otherwise
• Multiply the result by 1/2 for mindless creatures, 3/4 for Barbarians, Valkyries or animals, 3/2 for healers and knights, 2 for Priests, Wizards or dedicated casters, 5/2 for Wizard of Yendor

Spellcast failure uses the vanilla formula with these values:

Who                 Base   Emergency   Shield   Suit   Stat
 Wizard of Yendor      1          -3        1     10    Int
 nurses                8          -3        1     10    Int
 dedicated casters     3          -1        1     10    Int
 everyone else         8          -1        1     10    Int

Monsters always use their intelligence with casting (whose base rate before helms of brilliance is always 20 for Wizard of Yendor, 18 for dedicated casters, 11 for everyone else). In addition, monsters represented by an A doesn't get the cast penalty from casting using a large shield.

Whenever a monster is generated, it is assigned a list of spells. This is done by rolling a spell with equal probability for each of them, potentially rolling the same spell more than once, a certain amount of times: 10 + rn2(XL+5) for dedicated casters, rn2(XL/3) for everyone else. This spell is then added to the monster's spell roster with a probability of (2 + Spell level + Skill level) / 6. Skill level is 0 (unskilled), 1 (basic), 2 (skilled), 3 (expert). In addition, monsters with at least Basic skill in attack spells are guranteed force bolt.

Some monsters, mainly uniques, but also some additional ones, are generated with a fixed spell list. Those are listed below.
