Forgotten Horseman is a simple 3 stage boss. Triggered by forgotten stone picked up by the mob on the first floor of spire. ~5% drop rate.
- Stage 1: Regular mode, just a mob riding a horse. However, right before you kill him, make sure to run to the very right side of the map. This will help you in stage 2.
- Stage 2: Split mode. The head and horse will now split apart and attack you separately. If you ran to the right side just before killing the first form, the horse will not attack you.
- Stage 3: Phantom mode. Similar to the first form but with much more health and damage. I would suggest 3 people to take him out at first all around lvl 25-30. Make sure you have a tank and dps.
