- Demonic Spiders: Too many to list.
- That One Boss:
- Sausagefanclub in games 1 and 2. That unknown attack causes a ton of status effects. Plus, he can instantly kill your party members.
- Adumrod in game 3. Does tons of damage per hit - especially with his super attack - and has a decent amount of HP. Plus, there's a punishing miniboss before him.
- That One Level: The two ruins levels in Advent 2 are brutal. They're sequential, for one. Also, each floor is pretty long, and big. The enemies are good at inflicting annoying status effects, and have high HP. Also, there are TWO bosses.
YMMV / Advent Of The SMLPS
