I’ve DMed a few campaigns but it ends up early on making some of my players godly, while some have none above a 12.

I know in the players handbook it recommends giving a set of stats to use, but I was wondering if there was a rule or way you have a certain number of points that you separate into each stat?

Any ideas?

The optional score generation methods are in the PHB chapter 1, section 3.  The standard array is 15, 14, 13, 12, 10, 8.

Point but us a little more complicated, but not too hard. It’s in that same section. 

Ok thanks! I completely didn’t read that section on point buying. 

Ad a DM you decide ability score generation method wihin  parameters as you want. You can even use lower standard arrays, less than 27 point buy, or 3d6 instead of 4d6drop the lowest. if you want.

Point build is not perfect, but it's a lot more balanced than rolling stats.

We play a game of Yahtzee before every campaign to get out the silliness and then we point buy. I like it because:

• No Mary Sue/Marty Stus who got lucky once and coast on that throughout a campaign that could last years
• No Mary Sue/Marty Stus who have no room for growth because they're already maxed out when their adventure starts
• No severe underachievers who beg the DM for a reroll
• No severe underachievers orchestrating character suicide so they get to roll again
• No severe underachievers just slowly losing interest because they're not good at anything

No, good roleplayers make good roleplay. You can accentuate faults and play up strengths regardless of your stats. Someone with an 8 INT can have just as much fun roleplaying a dummy as someone who rolled a 5.

But if your table likes it, more power to you. It's just not for me.
