Are you referring to the story straw hats? And what do you mean by second skulls? None of those need more than one skull, and besides, they aren't all that great anymore.

There's only ever one treasure map out at a time and none of them are recurring. You should buy one copy of each one you don't have with the blue tickets you get by farming treasure map. All the TM characters are boosted in every treasure map, so you should use them as often as possible to max their mastery points. The only one's that you should worry about maxing their LB potential ability ASAP are Hancock and Shanks because they have the double special ability.

The newest Coliseum's and raids are the one's you should be focused on farming the most, but only if you can safely beat them. You should never use gems to revive. There aren't really any of them that would qualify as "useless" except perhaps Rebecca and a few others. Just check out their abilities beforehand to see how good they are.

For the most part, you should only pull on sugo-fests that have a 2x or better legend rate, or maybe something really good guaranteed. Most of your gems will come from clearing Chopperman missions and the daily events that give you a gem for clearing them once.

For the most part, your best captains are going to be legends, so even if you don't have their special maxed, you should still be using them. Most RRs are usable even if they don't have any skill-ups, you just need to stall a few extra turns with them.

You get manuals for legends and RRs by farming fortnights. Just make sure you don't try to raise their special levels except when there's a 2x or better skill-up event happening, same goes for Coliseum and raid units.
