Recently I played through FFT again and this time I resolved to get a hidden item I had missed on previous playthroughs: Elmdor's Cursed Ring war trophy, from the castle roof battle after Velius.
Except it refused to drop.
If you go into the ENTD of that battle, Elmdor does indeed have a Cursed Ring set for his war trophy. Presumably you were supposed to get a bonus item if you managed to knock him out instead of just bringing him to critical or beating up his arm candy. I never really messed with events but I get the feeling his end of battle message and/or teleport stops him from actually giving you a war trophy.
If there's an easy fix to this I'd like to apply it. If not, well, just another random bit of trivia hidden in FFT's data.
Teleporting out removes the unit and their data from the map, so you wouldn't receive his war trophy.
Sadness.
