Well...as for the bugs above...
Not sure what's going on with that item drop...could be collateral to using Yousei's editor...?
Beats me, but the message is borked. The game tells you that you have to take the item, and that's the message that comes up...
The trail near Troia castle was just superficial to the dopey tower of zot wannabe I put there...LOL I was really just playing around with the map editor.
The general consensus in other FF4 circles, including the Japanese, is that Zot is a high-flying floating fortress left by the Lunarians at some point in the past (the idea I've heard is that it was supposed to have been an observation platform used/built by KluYa or FusuYa to keep tabs on events on the Blue Planet).
Someone needs to master Mode 7 and make that dream happen.. someday.
I think the Charm Arrows will probably be sold somewhere in future hacks. I read your post about tweaking the arrows and bows, and those are great suggestions I will probably use some of that.
Well, my ideas probably break some balance somehow (I don't know what exactly, but it would break some of the early game monsters to an extent...), but the basis is to restruct the damn weapon to be useful and to keep all arrows relatively useful when you obtain them and keep them that way throughout the game. It's sad that the Lit arrows have almost no impact when you are in the Giant (like, Rosa does approximately 1000-1500 points of damage, and that's unacceptable IMO).
Samurai/Yoichi Arrows should be normally sold by Kokkol along with the Shuriken and Ninja Stars/Fuma Shuriken after you have him forge Excalibur.
IIRC, you replaced the arrows with whatever you renamed as the Ninja Sword. Not worth buying at all...
