Take modifiers and abilities. For instance having an odd number in an Ability is a bad idea. No one explains this to you, and the "suggested stats" and even party characters have poor stat distribution.
Further to that, it is actually good to start with an odd number in some stats. Later on, when you get to the appropriate levels, you get to add 2 points to those stats. If they are odd, you can raise two stats at the same time to levels that gain better bonuses.
This is something that people new to D&D need to know.
Odd Numbers are never good.
Unless you are in a situation where you:
1. Know you are taking a feat that gives +1 to a stat
2. Get odd numbers because you have lots of bonuses to stats (Human can get this situation)
3. Don't use points buy, and have to deal with the stats you get.
You get very few Ability Score increases in the game. Another thing the game should tell you. You starting distribution is very important because of this.
BG3 is level 1 to 10, meaning you only get an ability score increase at lvl 4 and 8 (unless you are a fighter who also get's it at level 6)
That is a total of 4 extra ability points.
What stats you want high really depends on your class. But in general most classes want at least two stats high.
BG3 uses points buy, where each ability score costs more the higher you want it. 15 in a stat costs 9 points, 14 costs 7. Both 15 and 14 gives you a +2 modifier. So if I take 14 in Constitution instead of 15, I can actually set another stat to 10. 10 being the +0 modifier point. Going from 13 to 14 also costs 2 Points, This means I could have one ability at 13 and one at 15, or two at 14. In one build I have a +1 and +2 modifier, in the other I have two +2 modifiers. And it cost me the same number of points buy.
At level up, I can put one point in the 13 and 15 and increase them to 14 and 16. Lot's of improvement. But I could take my two 14 stats and increase one to 16. The result after level up is the same, but with two at 14 I have had 4 levels of +2 modifiers in two stats.
And at lvl8 I can take that 16 to an 18, or that other 14 to a 16 too.
So unless I have "points buy to spare" and can bump an 8 up to a 9, or I know I'm taking a feat that gives +1 dexterity or something, I never put a stat at an odd number.
Odd numbers all the way.
To me a race is good when it gives you a +2 to your core ability and +1 in another. That means I generally can get those two skills to 16, and then my third valued stat to 14, while still not going 8 or 9 on the rest of the skills.
