Sage Advice
WotC publishes a monthly column with errata and official rulings on certain things. Answers from each column are compiled into this document.

Character Creation
- Point Buy: see section "Variant: Customizing Ability Scores"
- Available Points - 27, point cost increases with bonus
- Maximum Attribute Before Racial Bonus - 15
- Minimum Attribute Before Racial Bonus - 8

Language
"Common" exists as "Ubrekti", a sort of Latin-facsimile lingua franca. Human languages have subdivided into several regional tongues, and all human PCs speak Ubrekti and one regional language. Dwarves, elves and gnomes have all maintained enough regional homogeneity that they only have one recognized language apiece, although dialects are recognizable to the trained ear. The old halfling language has been lost to imperialism (more rule-specific details in their section).
While scholarship does exist of the various monster languages, few people care enough to make any special distinctions. For character creation purposes, monster languages may be chosen as they exist in 5e, and any rules differences that come up will be handled in-session.
