Nimble Escape. You can take the Disengage or Hide action as a bonus action on each of your turns.
Send In The Goblins (Recharge 3). Let out a cry to rally your goblin minions. As a free action, summon 1d4 Goblin Minion units to a maximum of 5 total. These minions appear within the closest safe spaces near your boss and share your turn order.
Hey You, Listen Up! As a free action once per turn, you can issue a command to your group of minions, which they do their best to obey. You can specify a simple and general course of action, such as: Attack that creature, Run over there, or Fetch that object.
You cannot give individual commands to each minion. Minions are eager to please their boss, so they will all attempt to fulfill your command.
After the creature completes the command, until they receive further direction from you, they defend and preserve themselves to the best of their ability.
