Safe Adventuring
This page tells the minimum moxie required to adventure in an area without ever being hit by the monsters you will find there. This is determined by multiplying the monster's XP values by five to find the monster's level. Monster level is the average of the monster's attack power and defense (muscle and moxie). Generally, these numbers are equal. To evade every attack, you must have 9 more moxie than the monster has attack power. These formulas were derived by Kittiwake and Crawly, the former of which compiled the list on the forums.
The two tables below both show the required Moxie for safe adventuring. The Sorted by Location shows locations sorted in the standard Wiki location order while the Sorted by Moxie table shows sorts locations ordered by the Moxie required for safe adventuring. Thus, knowing your current Moxie, you can figure out at a glance the areas in which you're reasonably capable of adventuring.
