1. Gargoyle vs. Skeletons
Here are a few different approaches:
1. The Dark Knight kills elves, takes damage from skeletons, then hides, followed by summoning elementals.
2. The Dark Knight moves among the skeletons, takes slightly less damage, then hides, followed by summoning elementals.
3. The Dark Knight kills elves, moves a second time, then follows step 2.
4. The Dark Knight moves among the skeletons, moves among them again, leaving approximately 500 health – there's no chance of winning.
