How do you distribute ability scores?

An ability score is determined by rolling 4d6 and discard the lowest score. This is repeated six times and each score is placed next to the ability where they are wanted by the player. This method tends to produce higher than average scores, which is more appropriate for a heroic character.

How strong is 20 str?

At 20 strength your carry weight limit is 300 lbs (which is approximately 136kg). This will encumber you but even so, this is a serious amount of weight when you consider Hafthor Björnsson (Aka the Mountain, and the world's strongest man) broke the record when he deadlifted 1,105 lbs.

How do you roll for the ability score modifier?

To determine an ability modifier without consulting the table, subtract 10 from the ability score and then divide the total by 2 (round down). Because ability Modifiers affect almost every Attack roll, ability check, and saving throw, ability Modifiers come up in play more often than their associated scores.
