if u mean pt from angel beach (cook island lvl 3), ruby rings help a bit: https://moot.us/lounges/415/boards/2002/posts/5436612/perfect-ruby-ring.
but tbh, even after u can buy ur own and borrow friend's staff with max-level perfect rings, the chance of getting the pt is still really low (like <10%, u can check by looking at the icon when choosing staff for expedition), so it might not be worth it unless u hv coins to spare or rly like the pt
btw theres a bug w the ad system where u can repeatedly get the "reward without watching ad" to hatch eggs (or for any other ad thing) wo waiting for 3h or actually watching ads as long as u hv enough eggs n incubators. idk how to trigger it on purpose, but when it happens as long as u don't close the app u can use it as many times as u want, so u can try checking whenever u get that msg ^^how to get pet? 5
