Finally got to the end of episode 30. I'm glad i marathoned the episodes 29 and 30 to be able to see the end of this story line no matter what happens!
Maybe the loss of the figurine will make the players more prone to listen how a magical item works for reals.
@AdamKoebel How are you going to handle AoE spells and LoS? AFAIK spell effects (such as damage) wrap around corners without any problem if the spell doesn't specify otherwise. 15 feet of Spirit Guardians is pretty massive bubble in tight spaces. For Spirit Guardians it's clear that you need to see those who you don't want to be taking damage, but would someone take damage behind a wall even if there was no doorway? I mean the spell is spirits flying around and they really don't care about walls.
PS: As a DM i'm of an opinion that SG is a completely crazy spell. Enemies can't even reach the center if they don't start at the edge of the spiral due the rough terrain modifier. Forget Fireball, that's easy to tank with save and damages only once. This thing can go for 100 rounds!
