My group is playing Abomination Vaults, and on the second level there is a room with an undead Minotaur Skeleton Warrior. The book specifically states that it never leaves the room it’s in.
My group quickly figures this out and would simply have everybody ready an attack, one PC would open the door, triggering everybody else’s reaction, and would then close it again.
After doing this about 10 times they finally took down the skeleton despite it having resistance to most of their attacks, with none of them taking any damage.
This is a somewhat inexperienced group that doesn’t usually do strategy things, so I was happy to see them plan and execute.
Anyway what’s the weirdest way your group beat a supposedly challenging enemy?
I see this as an excellent strategy to use with inexperienced players.
Let the gamify the tactics a little, give them a false sense of security and then BOOM give them a genuinely intelligent opponent that makes them pee their pants
Oooh, or you could bring in another player to play the enemy similar to this greentext (tl;dr: FelixLaVulpe tells the story of playing a minotaur against an min/max adventuring party at the DM’s request. Spoiler, it goes very poorly for the overconfident party)
That greentext in turn reminds me of Tucker’s Kobolds
