Fun game. Started this morning and made it up to the Imperial Camp so far. I also did the daily GIL dungeon (managed to beat it on easy and normal), since from what I've read money becomes a bottleneck. I'm also on the 6th level of the ongoing event, though I don't think I've gotten anything useful from that so far (other than Cecil, I think!).
It's not entirely clear to me what determines whether I get "Mastery," though. I've had Champion status in all but the final boss and sometimes, but not always, that's sufficient...
Also, is it worthwhile to upgrade some equipment? I figure the 1 and 2 star stuff is just going to be fodder to level up better gear... but what about the 3 star stuff?
I also have a ton of minor orbs. Should I level up my 1 star abilities, or is that just a waste? I almost never run out of ability uses, and it's not clear to me whether it merely gives me more uses or also strengthens the skill.
Getting Mastery is dependent on you meeting certain thresholds for each fight, total number of actions, whether you abused a bosses weakness, how much damage did you take from enemies and if anyone died. For instance to get mastery on the FF IV Mist Elite dungeon, you cant attack the dragon while in mist form or youll not get mastery.
As far as equipment, that seems to be the entire game and is much more complicated to answer. Basically, youll need to level up gear for each of your characters that corresponds to the content you're doing. For instance there is Leather Armor (VI) that drops that is a 1 * armor, however when you upgrade it, combine it twice, it becomes a 3* FF VI armor that is best in slot for FF VI content.
This doesn't really begin to matter until you face elite dungeons and much harder content. I can safely say you wont really need to worry about the synergy until you're almost completely done with the normal dungeons but it doesn't hurt to save this gear for later use, all you need is 3 sets of an item to max it but with only 100 inventory slots, it can fill up fast if you go for everything. Keep in mind it is very easy to come back to these places and acquire it again.
For current priority FF 4 and 6 gear. while 7 gear will be important ONLY if the next event follows the japanese version timeline, with Aeris being released.
You can find the links on the first post of this thread for lists of all documented drop locations and their synergy if you ever feel like searching or being aware of what drops in the content you're doing.
As far as orbs go, honing abilities only grants you more uses and doesn't make them do more damage. Most bosses in the game are weak to thunder at this time, while the current event boss is weak to fire and the only boss I know of at the moment that is weak to ice is ant lion in FF IV.
Currently I use Thundara (lesser orbs) Fira (lesser orbs) and working on Blizzara for ant lion. I never really used the minor spells because my melee characters destroyed everything without any necessity of black magic til I hit my mid 20's. With the exception of Cure, which, well, is a heal and can definitely benefit from some honing.
I'll also add, I recently sold all my minor orbs while trying to get together all the Gil I needed to upgrade my shit... and made over 160k gil from selling minor orbs, so, you CAN hone them, to double down on any weakness a boss has, if you dont already have 2 of the higher tier magics. Otherwise, sell them bitches.
