You Might Want to Begin to Prepare Yourself for Disappointment.
The grillos in the book are less of an acute and more of a long term threat. They are pretty unattentive and focused on themselves (there's a slight reflection of that in my stats in that their Wis is so much lower than their other mental attributes, but I couldn't bring myself to actually make it negative). "It should be enough if you don't think too intensely about them," as deuteragonist Havarius Opal said. On the other hand, that wasn't enough when Princess Dyhlia and Opal had to go through teeming masses of them. Dyhlia managed to avoid them by focussing on one of her hobbies: inventing completely useless and crazy stuff in rainbow colors.
