No class, no saves, no problem: All in the Attribute Scores

An opposite approach from what I did in here is to ditch classes, level and skills and choose the other abstraction to build the system around: The ability scores.
Wisdom decides how well a cleric you are. Dexterity does that for thieves. Strenght doesn't really work for fighters, however, as there are other factors that might decide in how good a fighter you are than your bulk body power, so I'm using CON instead
The most obvious advantage on using ability scores is that it keeps the thrill of rolling a character (instead of just rolling the HP), and also allows checks by rolling under the given ability score. For a game with both clerics and wizards WIS and INT can be separated. I prefer to merge both concepts into an attribute called MAG.

When you create a character, roll 2d8 in order (yeah, that will produce below average guys) Mods, however, can't go below -1. Positive mods ALLOW you to perform certain tasks,  and you still roll under score to see how well you perform (having +2 STR is better to force doors than just +1 even if you can attempt it with just +1)

STR: Mods adds to melee damage. +1 allows for force doors, +2 allows to bend bars
DEX: Adds to missile. +1 allows for easy thieving skills like pickpockets, +2 allows for advanced thief skills like climb sheer walls. Used as a reflex save.
CHA: Your common hireling/reaction mods. Also used to save VS any soul or mind controlling effect (willpower save).

CON: This amount is literally your Hit Points, and also says how well you are as a fighter. At +1 you get an extra attack with your favored weapon, or maybe some armor. At +2 or +3 you get extra attacks regardless of weapons. Read the last articles to know more about my stubborness of claiming that Fighting Prowess is indisoluble from Having more HP. Can be used as a Fortitude save but I'd rather make that kind of things just drain HP
MAG: How much magical shit you know. Roll under this to detect magic or to get a glimpse of the otherwordly side of your surroundings.
At +1 you get a 1st level spell
At +2 you get a 2nd level spell and two 1st level spells
At +3 you get a 3rd level spell, two 2nd level spells and three 1st level spells.
Rearrange spells to fit in three level categories OR allow higher level spells to be cast using magical trinkets, magical places or other aids.



Provisional score to mod conversion:

2-8: -1
9-12: 0
13-15: +1
16-17: +2
18:+3


Evidently, in a game deprived of levels or other mechanical parts, when you "level up" you raise your ability scores (thats why I had them start low at 2d8). Maybe raising 2 points at will per level, always capped at 18.
And that is how you become a better figher/wizard/thief, not by picking it as a class.


Rolling certain distributions at the start might give you the chance of playing an ELF, DWARF or any other, like a class requirement. Then you get the darkvision or knowledge about caves; thats the only way to pick them.
