Additionally, when you take the Attack action, you can forgo one of your own attacks to allow your familiar to make one attack of its own with its Reaction.

Dark One's Own Luck

You can call on your fiendish patron to alter fate in your favor. When you make an ability check or a saving throw, you can use this feature to add 1d10 to your roll. You can do so after seeing the roll but before any of the roll's effects occur.

You can use this feature a number of times equal to your Charisma modifier x4 (minimum of once), but you can use it no more than once per roll. You regain all expended uses when you finish a Long Rest.

Contact Patron
-In the past, you usually contacted your patron through intermediaries. Now you can communicate directly; you always have the Contact Other Plane spell prepared. With this feature, you can cast the spell without expending a spell slot to contact your patron, and you automatically succeed on the spell's saving throw.
Once you cast the spell with this feature, you can't do so in this way again until you finish a Long Rest.

Fiend Patron
Fiendish Resilience

Choose one damage type, other than Force, whenever you finish a Short or Long Rest. You have Resistance to that damage type until you choose a different one with this feature.

Inspiring Leader
You can spend 10 minutes inspiring your companions, shoring up their resolve to fight. When you do so, choose up to six friendly creatures (which can include yourself) within 30 feet of you who can see or hear you and who can understand you. Each creature can gain temporary hit points equal to your level + your Charisma modifier. A creature can't gain temporary hit points from this feat again until it has finished a short or long rest.

For that duration, you have Advantage on Strength checks, and your Speed increases by 10 feet. Once you use this trait, you can’t use it again until you finish a Long Rest.

Hill’s Tumble (Hill Giant). When you hit a Large or smaller creature with an attack roll and deal damage to it, you can give that target the Prone condition.
