Thirteen knew that even if they lured the Yellow Striped Dusk Brute into one of their pitfall traps, it would not really do much damage to its body due to the hard scales that protected it.
Their wooden and stone spears would not even put a dent in its armor, so their weapons were more or less useless.
The only realistic thing they could do was to let Brutus and Bruno tag-team to smack it into submission with their Spiked Mace and Bone Club.
However, they weren't exactly the fastest-moving monsters in the Houdini Desert.
The Monitor Lizard was also slow-moving, but it had something that the two Brutes didn't have, and that was a poisonous spray attack that could kill the two Avatars in minutes.
Over the past month, Thirteen had strategized a way to overcome its deadly weapon, but in order for his plan to work, Brutus and Bruno had to get close enough to execute his plan.
In fact, they had to get extremely close, which was the main problem.
