There were various traps in this Labyrinth of Terror, the most frequent being arrow traps. Unfortunately, these did little damage to the iron-maned bear.
Even after taking dozens of them head-on, it was only slightly injured. Moreover, beast-type monsters have good recovery abilities, so a few minutes of rest would certainly have restored it.
Thus, Adall sought to make it fall into a much deadlier trap, a trap known as the spiked pit. He had spotted one after exiting the second boss chamber and, as with many other traps, he managed to pass it without triggering it.
So, like a master walking his dog, he led the bear to a destination from which it would not return.
Adall could now see the exit of the second boss chamber in the distance.
All he had to do now was to continue his run and jump at the right moment to avoid triggering the trap. The bear, far too heavy for such a spontaneous movement, would then be inexorably doomed.
