Lone Wolf

As long as you are the only player character in your adventuring party, you gain the following benefits:

• Your hit point maximum is doubled.
• You roll for initiative twice, and act on each of the turns. Your first turn counts as your "turn" for the purposes of resolving effects such as "At the start of your next turn." You also get one additional reaction per round. Being incapacitated only affects one of these turns, unless you are incapacitated a second time.
• You can concentrate on up to two spells at the same time. If you fail a saving throw to maintain concentration, only one of the spells (your choice) ends.
• A short rest takes only 1 minute, instead of 1 hour.
• If an ability causes you to regain expended spell slots, you regain twice as many.
