The last day or so, I've been playing around with Encounter Rates and Trapped Chest triggers, trying to figure out how they tick.
ENOUNTER RATES:
Now, I notice that when it's set to 0, there are no encounters for a map. I also notice that at least a couple of dungeons are set to 8, wheras a few others (near the end of Lunar Subteranne) is set to 4. I figure "Okay, I'll set Watery Pass to 16 instead of 8 to cut the encounter rate in half!" but upon testing, it didn't really seem to do much of a difference. Setting it to 1, however, certainly made the place much more annoying to traverse, lol.
I understand that the Random encounters are well, random, so I set the ER number to 123. A little bit of a difference (or perhaps I was just lucky?) but not a whole lot. In the editor this number can go up to 255 - but can it really be set that high? Do the higher numbers even mean less encounters (like I assume based on looking through some of the other maps)?
TRAPPED CHESTS:
Now this one kind of confuses me, though I think I have some sort of grasp of this. When you set up a Trapped Chest trigger, you're allowed to use formations 449-512. I've been playing around with it, seeing which formations will or won't work with the map I'm putting it on (Watery Pass 4F). At first I tried setting up a new formation (506) to use (3 Souls, and 2 Skulls), but when the fight starts I'm fighting a Medusa, Gorgan, and Steelman instead.
Now that I think about it, since it's limiting me to a certain chunk of formations, perhaps half of them are used for the Overworld, and the other half of them are used for the Underworld/Moon.. it would make sense of why my formation acts the way it does. Back to experimenting.
