Rolling stats

Either:

• 3d6 and arrange freely, or
• roll 4d6h3 in order down the list, or
• roll 3d6 in order down the list, but for one ability score you may roll 6d6h3.

The first lets you roll and customize; the second lets you roll and have slightly above the fold on average.  The last makes someone who is likely to excel in one particular ability of your choice.
