Buzzing Conjurer's Whistle

Summoning Call. You can use an action to blow on this whistle, which makes a sharp and high sound with a faint noise of buzzing in the background. When you do, you summon 4 Giant Wasps. They appear in unoccupied spaces that you can see within 60ft. of you. Each beast is also considered Fey, and it disappears when it drops to 0 hit points or after 1 minute has passed. The summoned creatures are friendly to you and your companions. Roll initiative for the summoned creatures as a group, which has its own turns. They obey any verbal commands that you issue to them (no action required by you). If you don't issue any commands to them, they defend themselves from hostile creatures, but otherwise take no actions. The whistle can be used once per day, and regains its use after the next dawn.
