Racial Ability Score Modifiers with Monster Races?

[Silence among Hounds]

As a Gamemaster, I am currently work on a campaign that involves a significant amount of centaur, kappa, Minotaur and bugbear. Any methods to reverse engineer them for the racial stats?

Yes; subtract 10 from all even scores and 11 from all odd scores. The result is the racial ability score modifiers.

For instance, a centaur has racial modifiers of: +4 STR, +4 DEX, +4 CON, +4 WIS, +2 CHA.

Bugbear Str+4 Dex+2 Con+2 Cha-2.

[Silence among Hounds]

I am extremely confused. I used Are's method and found that the Bugbear would have a racial modifier of +6 strength +2 Dex +2 Con and -2 Cha.

My Bugbear stats come from Reincarnate.

So, RAW.
