OK, I feel like either we’re missing a key strategic point here, or we’re the unluckiest raiders on the planet.
Here’s the problem: We all stack on the green-slime-victim. Slime gets there, we get thrown back. Inevitably, someone gets thrown into a pool of green goop. The person dutifully tries to move OUT of the goop, but cannot, because the slime is now focused on the person in the goop, immobilizing him. So we try to finish off the slime, but the person in the goop quickly dies, despite our best efforts. We lost a healer TWICE this way.
Here is a reenactment of that horrible event. Remember, no stick figures were harmed in the making of this drawing.
