Chap 5 ghost archer: at the start of the map Elc fights an enemy archer and the cri rate is 2%, if the archer got killed you still see him on the map
Nergal is not a Dark Druid?: in the story before chap 30E/32H when Nergal talks to Limstella his sprite ont the map is the same as a normal druid....(so he got promoted just after that??)
Ninian/Nils's rings: you can keep the effect the ring give for more than one turn, just have the character with the effect rescued by any other character and drop he/she next turn and the effect will still be there. Useful in Arena, just use sing/dance on the character so they can move again.
Mounted Units move again after attacking: if you let any mounted units attack enemies while standing on a trap square (one that shoot out fire for example), they can move again after attacking if there is any movement left.
