While wearing this belt, you gain the following benefit:

• Your Constitution Score changes to 22

In addition, while attuned to the belt and while Shifted, you can use an action and speak the Driver's command word to further your lycanthropic transformation for 1 minute once per long rest, giving you the following benefits during the time limit: 

• Your movement speed increases by 10ft.
• You gain 1d4 times your level temp HP.
• You deal an extra 1d8 lightning damage with every hit. This increases to a 2d8 at level 4, 3d8 at level 8, 4d8 at level 12, 5d8 at level 16, and 6d8 at level 20. 

However, when the Driver is activated, you cannot cast or hold concentration for spells other than cantrips. If the time limit of 1 minute is exceeded, you gain a level of exhaustion for every round that the belt is activated past the limit. The Driver can be deactivated at any time, also causing you to lose any remaining temp HP as well as gaining the following detriments for 30 seconds: 

• Your movement speed decreases by 10ft. 
• You loose any resistances or immunities given by any means. 
• You take 1d4 lightning damage at the start of your turn. This increases to a 2d4 at level 4, 3d4 at level 8, 4d4 at level 12, 5d8 at level 16, and 6d4 at level 20.
