How you get here
Use the unlocked alternate exit. The ordinary Mines/Ashpit entrance requires two explosions.
Prepare before the checkpoint
- Save enough bombs for the entrance when following the standard route.
- On floor II, find the rail switches and minecart entrance.
- Learn the chase route and hazards rather than relying only on the power of your current build.
