New player here. How does a weakling make an intermediate level weapon page? I've read some guides, and I understand you need to participate in events to get SSR weapons, but how do you get enough strength to reach that point? What SR weapons do you grab as placeholders?

The store has a wind and fire SR weapon that gives an ATK skill, but is it worth buying?
What about farming prison disaster raids? Which weapons will they drop that has ATK up skills?
Is it more important to have a grid of high level uncapped weapons of different elements, or one with as many SRs of the same element with ATK UP skills, even if it means having less uncaps?

Sorry if I'm asking a lot. I want to understand how I should be spending my AP outside of daily quests right now. I'm reaching a point where the Advent Union battle thing is becoming a struggle to fight against really quickly...
