You guessed it! It's a new difficulty mode. True Expert mode, other names are Master and Extreme mode.I realized while making this would be better as an item that activates the mode
Compared to expert mode:
Enemy HP, ATK, and DEF, coin and item drops are increased by 50%
Increased enemy spawn...
Ninja Ambush :kingslime:
This would be an event that randomly happens at night, after a mechanical boss has been defeated
Can be summoned with a Ninja Reinforcement Caller
As for the enemies:
Most ninjas would be slow and invisible until either within 10 tiles of the player or get attacked...
