 From observation, with a straightforward randomization approach, about 75% of seeds end up being "Hook seeds", i.e., seeds where the Magma Key is not readily available and the Hook is required to access the underworld, a much more difficult route with two challenging boss battles. From observation, with a straightforward randomization approach, about 75% of seeds end up being "Hook seeds", i.e., seeds where the Magma Key is not readily available and the Hook is required to access the underworld, a much more difficult route with two challenging boss battles.
  
-To ease the difficulty for newer players, when generating a seed without any of the extended key item position flags (summon, moon, and traps), the randomizer has a 50/50 chance of forcing a Magma Key underworld route to be available. This will be the 'logical' route, guaranteed to abide by any safety checks.+To ease the difficulty for newer players, when generating a seed without any of the extended key item position flags (summon, moon, and MIABs), the randomizer has a 50/50 chance of forcing a Magma Key underworld route to be available.
