Question
How to make sure that a player that rolled awful stats will still have an awesome time at the table? What possibilities are available for the DM? Would it feel cheap to find stat-boosting items? What can players do to make sure that player is still having fun?
The simple solution of re-rolling the stats is out of the question. The adventure has already begun and it would feel very unsatisfying if the original rolling carried no weight at all.
Background
Starting a new adventure, we all decided to roll stats (highest 3 of 4d6) for our new characters. Most people rolled stats close to what one would get with point-buy, but one player had all stats in the range 8 to 11 and averaged below 10 (which is worse than a commoner).
The players are all quite new to the game and it is the debut for the GM. We all had some laughs on the horrible rolls and everyone is still having fun. The player has not complained yet, but my worry is that it will feel less fun in the long run.
The player picked druid, so they can wild-shape away the physical stats at level 2.
