I'm brainstorming a character concept, a tavern brawler specialist that summons a variety of random items usually found in a bar (just because he is more familiar with those than regular weapons). He will be a level 3 Hexblade Warlock with Pact of Blade and have the Tavern Brawler feat.
I intend to utilize the third option of Tavern Brawler feat to grapple enemies hit by my pact weapon:
When you hit a creature with an unarmed strike or an improvised weapon on your turn, you can use a bonus action to attempt to grapple the target.
Tavern Brawler requires I hit with an improvised weapon, so I intend to summon, for instance, a kitchen knife, a bottle, or even a rolling pin or a pan, just for the hilariousity. And yes, the character will be a female dwarven innkeeper.
So, can I use Pact Weapon to summon improvised weapons? Or is the Pact Weapon required to be a conventional weapon? Can it be a kitchen knife that counts as dagger and improvised weapon?
