No, Proto-Turk Light was just supposed to be a regular attack that he throws around, like Electroprod. I actually saw this in action this morning, when watching someone's playthrough. The Pyramid enemy moves around but the 'effect' stays on the original Pyramid target, from what I can tell. Seems (sort of) harmless but it's too confusing so I'll probably remove the attack.
EDIT: I'm currently making a char.lgp using ULGP that'll hopefully be able to decompile through that program. Could you let me know if you were able to decompile and recompile the battle.lgp and flevel.lgp?
Battle.lgp and Flevel.lgp both worked fine on my end.
Edit: Just cleared the Shinra Tower. The difficulty really seems to be picking up; I'm loving it.
The elevator battle seemed far too easy, though. Aerith and Barret are definitely back-row characters, and Red XIII arguably is too with his fairly high magic stat. I only had to cure-all once throughout the fight :/
Motor Ball, on the other hand, was
brutal. His phase-change attack (something Flames, I forgot) was hitting for almost 600 damage on unprotected party members. Wound up having to give Barret and Aerith Fire-Elemental armor, give Cloud the Talisman, and start the fight with MBarrier. When I finally brought him down, Cloud was dead and Barret and Aerith were both in critical. Dunno how the fight would be possible without that second Elemental materia.
