Global Skill Proficiency Buffs

Every character receives one extra skill proficiency at level 1 during character creation.

Every character has proficiency in improvised weapons by default at level 1.

(No longer) Optional Features

If a class feature is labeled as optional, but does not replace another feature, it is no longer optional. The DM can ignore this rule if the optional rule does not fit with the campaign (e.g. Artificers getting firearm proficiency in a setting with no guns, Universal Existence on previously setting-locked species, etc).

Feats are no longer optional rules.

Point Buy And Standard Array rework

Your pool of points to work with is now 30. You can now reach 16 in a stat, but going from 15 -> 16 costs 3 points. Standard Array is also now 16, 14, 13, 12, 10, 8.
