From an adventurer's league session:
*We may not capture the goldfish handler with an animated rope bridge.
**The party may not intimidate him using the aforesaid animated bridge and a necromancer with two blue skeletons
***The skeletons especially may not be called Oingo and Boingo
****We may not then kill alll of the prospective replacement goldfish and have the necromancer turn his familiar into a goldfish in order to have a spy.
*****We may not then follow him to the Xanathar's ship, sneak through the ship using the hide bonuses granted by some low-level spells, making even a roll of 1 be higher than the \perception of any creature on the ship, and steal what we came there to steal without fighting the Xanathar
******After that, we may not add insult to injury by unsummoning the familiar and having the Xanathar attack everything around him
