When using a crossroads potential laser (heals all nearby entities continuously), pokemon do not faint when they reach 0 HP. When both pokemon are at 0 HP, the battle system doesn't respond. The laser does heal pokemon to full when used outside of battle so I would assume what's happening is that the entity HP and the HP displayed in the battle gui are becoming desynced. I don't know of other mods that do direct, non-potion-effect healing in this modpack so I haven't tested if this is a crossroads thing or a non-potion healing thing.

One additional thing of note, if a move would bring a pokemon to 0 hp in one hit, the pokemon still faints.

Sorry for the late reply. I wasn't able to reproduce this yet since I couldn't find the item from the mod you're referring to. Would you be able to point me in the right direction so I can take a look?

Ah yeah potential lasers are any beam of mostly green light, made using the arcane extractor by inserting quicksilver (or other items) into one via a hopper or dropper. I've tested this using a continuous very strong beam, which can be made with an array of these pointing into arcane reflectors which point into a clockwork stabilizer.

Tried this again on 7.0.8, still soft locks after both pokemon are at 0hp. AI pokemon can still freely use moves at 0hp, but the player is not prompted to do anything when their pokemon is at 0hp but not fainted.

Tested using frozen quicksilver fed into an arcane extractor (aoe heal is at the end point of the beam) If testing with only these two mods, a chest of frozen quicksilver on a hopper feeding into an arcane extractor pointed at a clockwork stabilizer should work.
