Class Reductionism

 I have continued my thinking about simplifying multiclassing in my game. 

Tonight's thinking is thus: 

Multiclassing is only available for the four main classes. My alternate classes will remain, but any previously allowed multiclass using them will be outlawed (no Cleric/Rangers or Illusionist/Thieves). 

Going by the example set by the BX/BECMI Elf class, there is a single XP track and both class's abilities advance at once. Generally the multiclass will take more advantageous numbers from either base class, but demi-human level caps will take the lower. 

The numbers here are still provisional. The Elf uses double the Fighter advancement (the faster class) if you look at it one way, or the combined total minus 500xp at 2nd level if you look at it another. I went with the latter to figure out these numbers. The amounts for high level advancement were considering that spellcasters tend to get exponentially more powerful, but the MU/Thief is stuck with a d4 hit die, so they get a small boost. 

Multiclassing Rules:

• Take the most advantageous BAB track.

• Take the most advantageous saving throw for each category

• Gain all special abilities of each class

• Use any weapons or armor allowed by either class

• Use the custom XP track and advance both classes

• Use the least advantageous maximum level

Dwarf: Berserker (8), Cavalier (6), Cleric (8), Fighter (12), Thief (6), Cleric/Fighter (8), Fighter/Thief (6)

Elf: Bard (6), Fighter (10), Magic-User (12), Thief (8), Fighter/Magic-User (10), Fighter/Thief (8)

Halfling: Acrobat (8), Druid (6), Fighter (8), Ranger (10), Thief (12), Fighter/Thief (8)

Gnome: Bard (8), Fighter (6), Illusionist (12), Thief (8), Fighter/Thief (6)

Half-Elf: Assassin (6), Cleric (6), Druid (10), Fighter (8), Magic-User (8), Ranger (8), Thief (10), Cleric/Fighter (6), Cleric/Magic-User (6), Fighter/Magic-User (8), Magic-User/Thief (8)

Half-Orc: Acrobat (6), Assassin (12), Berserker (10), Cavalier (8), Cleric (6), Fighter (10), Thief (6), Cleric/Thief (6)

Still considering if I want to keep the Dragonborn and Changeling (sort of like Tieflings) or not. 

Also, my Acrobat class is an amalgam of the Monk and Thief/Acrobat. Assassin is what you'd expect, sort of a Fighter/Thief with an instant kill ability. Bard is a lore-master class, not a minstrel. Berserker is the barbarian (but no rage, no magic-item smashing, basically the Berserker monster turned into a class). Cavalier is a mix of the UA Cavalier and the Paladin. Druid is based on the alternate Cleric in the Companion Set as a full progression class. Illusionist is a port of the AD&D class. Ranger is also a modified port of the AD&D class. 

Assassin and Ranger are both basically a Fighter/Thief, only one is urban and the other is rural/wilderness.
