Also, monster counts for completion would be nice to know for prospective vanquishers.
1. I used a back & forth path for clearing out the area, keeping my trails fairly close together, using my spin-map & U-map to be sure I covered everything.
2. Using a path that takes you from the outer edges to the middle in a circular pattern is a great way to work on cartographer title while working on this one.
3. It appears that pop-ups will not count if they are not aggroed. But once aggroed, they must be killed to get the title.
4. Active quests will also affect spawn numbers in hard mode.
5. Some patrols cover a wide area, so be sure to take them out as you find them. (I noticed this in the Cliffs of Dohjok.)
6. Controlling your DP is very important! Don't save the tough mobs for last. If you take them on and get 15 - 30 DP, you can go take out some of the weaker mobs to reduce your DP. This is especially important when you're DP gets in the 45+ range.
7. When you've got favor, take advantage of the shrines! It will cost you some gold, but those blessings can make things easier and may save you from a wipe that will send you back to town from a failed effort.
8. If your with a group of people, and you can't seem to find that last group, spread the entire party out over the map searching. Once one of your party members finds the mob, you can all meet up and take care of business. NOTE: Be careful when searching on your own like this, you stay on previously covered ground. You don't want to get surprised by something hiding in the dirt.
