Hissing 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 hissing in the distance. When you do, you summon 1 Giant Constrictor Snake. It appears in unoccupied spaces that you can see within 60ft. of you. The beast is also considered Fey, and it disappears when it drops to 0 hit points or after 1 minute has passed. The summoned creature is friendly to you and your companions. Roll initiative for the summoned creature, which has its own turns. It obeys any verbal commands that you issue to it (no action required by you). If you don't issue any commands to it, it defends itself from hostile creatures, but otherwise takes no actions. The whistle can be used once per day, and regains its use after the next dawn.
