Notes

• Illithid Arcanists have 2 variants: one with Fire Shield: Chill and Fire resistance, and another with Fire Shield: Warm and Cold resistance.
• Their version of Magic Missile deals more damage, fires more missiles, and has a significantly longer range. This makes them dangerous if not dealt with quickly.

Loot

• Onyx
