Here is a guide to get pds to
buy some better gear.
You could also farm materials on normal difficulty using the quests Towards the Future Ultima for hildablue or wrath of forest for Rappies. Depending on your ID and what materials you want to farm.
id also suggest finding your max stat plan and either farming mats or buy them with pds and using them. That will make a big difference.
some cheap and easy to get gear would be
charge arms
charge mechs
charge handgun or rifle
demons hangun or rifle or bringers rifle
hell hangun or rifle
frozen shooter
v502
v101
heavenly arms
im sure there is a lot more I’m forgetting but those are some examples and they should all be easy to get with around 50hit or so
