A wizard is never late . . .

Guild/Order

You have gained membership in an organization of warriors (or wizards). That organizations base becomes a sanctuary for you and any companions and the organization will happily provide support for your endeavors in the forum of food shelter access to training grounds and lore as well as any other means short of marching to war. Although they might be convinced to do so. Your named weapon now inflicts a critical hit on a natural 19 or 20

Through Fire and Water

When you attack with any weapon you may add your proficiency bounus instead of your ability modifier to your damage.
At the start of your turn you may trade your +2 bonus to attack and damage for a +2 to your armor class.

That Only Counts as One

Nominate an ally during battle as long as the number of enemies you have each slain does not have a difference greater then 3, you both get a +1 to your attack rolls. If one of you out paces the other by more then 3 you both lose this bonus. You may only use this once per long rest.

You Shall Not Pass

Your named weapon is indestructible
