With the new drop rates coming, it'll be even better. What I used to do was run Max Attack runs in Ep4 and go through the first Rappy waves. Something like 30 spawn almost immediately. Do that, hope for a Del Rappy, get freaked out cuz they're scary looking, get PC, restart.
This is kinda why I am still playing PSO after N.A adjusted rare enemies to 0.7%, if they remained unchanged, it would've been like pulling teeth running max attack 4 50 times and not seeing any del rappy. With the new spawn rates, it feels like Christmas morning when I see a rare enemy pop, and makes me want to keep trying to see another
The photon crystal just supports this even more
N.A asked for feedback, here it is!
EDIT (because this thread moves slowly, I can add to my posts instead of a new one, lol)
Also... I tried to put an untekked Dragon Slayer into bank and I got lagged out during the transfer and I was automaticaly disconnected with an error 100, I went back to the same game I was in and I couldn't do anything with my items, would get disconnected if I tried to tek, bank, or even equip my items. FInally I just made a new game, and everything was working normally again
I looked into this and it seems that sega put in a new locking mechanism to prevent duping with lag, and you are locked with your items (disconnects you) if you keep trying within the same game...
Maybe if you desync with mags or the bank, try making a new game and see if your mag stats revert back to normal or not. Maybe it doesn't work, but worth looking into it
