All weapons are available to all classes.
Difference between classes can be done with fighting styles, number of extra attacks, "riders" on weapon attacks.
Extra attacks for full martial classes(fighter/barbarian) would be every 4 levels(1 attack at 1st level, 2 at 4th...6 at 20th)
For paladins/rangers/monks every 6 levels, 2 attacks at lvl6...4 attacks at lvl 18,
rogues/bards/warlocks every 8 levels, 2 attacks at lvl8, 3 attacks at lvl16
full casters extra attack every 12 levels, so 2 attacks at lvl 12.
All classes can wear all armor, but suffer armor penalty if they do not have sufficient strength.
Lightest armor can have str requirement of 8,
Heaviest armor can have str requirement of 18,
also no spell-casting without sufficient strength,
10th level spells at lvl19.
no ability boosts from racial bonuses, howevery every race(except humans) would have one or more abilities that would have minimum value and maximum value at 1st level.
In default array and point buy minimum score is 8 and maximum is 16 at 1st level. 18 would be max score available without magic.
