Yeah, I died on one of the bosses of the Sky Hawk one as I'm kinda underleveled, but just getting more/upgrading that is probably the easiest way to handle this while lacking clear info on what banes each jara has. I'll just try getting through that a couple times tonight, I guess. Grinding for a Miracle feels even more tedious, as nice as another would be.
I kinda gave up on trying to match Snacks as much as using recommended general ones, running Ciderella + Jennifer + uhhh whatever the lategame story assassin is called, so obviously changing that up can help some too. I got pretty dang close last time I tried, there's just that point where his attacks are more constant + can be aimed at more angles, and keeping people alive became a bigger problem. So I'll have to balance more damage with less survival.
Part of me wonders if it could be good to double down on that chest finding idea and just trying to do a few runs of even higher level quests, where I just run for the chests to hopefully grab some new jara + materials even if I have no chance of clearing? That could easily be a waste, but also may pay off well, hmm.
The big thing to understand about Miracle Grinding is, you aren't going for the points, you are hunting down chests from the dungeon and enemy drops, hoping for the Miracle chest event to happen that hooks you up, OR, you rush down the dungeon and hope you get a gold chest that hooks you up with the Miracle weapon. The points themselves are more of a bonus you build up to over time.
I mentioned the Skyhawk since that can be gained through dungeon crawling, even if you are unsuccessful in beating the boss at the end. I reccomend trying to develop a wider range of Jaras, and equip what you need to beat the enemies in the dungeon first and foremost, since then you can get some levels and get some chances at good treasure in the process!
I highly reccomend trying for a full eight-Jara set of Elemental Banes. There are plenty of Jara for the other types, Colour and Family, but having one Jara of each Element is the most efficient way to cover weaknesses since you only need eight to handle anything the game throws at you. That's why the Bewitching Weapons are such a good deal to go for, they cover elements at a Maximum Lvl 5 Bane, super powerful!
I'm hoping you can get some good gear for the future! Even if it's just a Lvl 2 Bane, having at least one of all eight elements (Fire, Ice, Water, Lightning, Wind, Earth, Light, Dark) will put you in a good place. If you have better banes for a different thing the boss you are targeting has, you can put that on too and cover it then, like how Coldimari is a Silver Boss, so the Clan Alloy Spear totally destroys him at Lvl 4 Silver Bane.
If you can run repeat quests of the White Dresscode mission online, you can get a ton of cash and experience, in case you feel you need to bridge the gap in stats and could use a bunch more cash. I did a ton of runs recently and it got me a ton of cash and Exp!
Also, don't forget to update your Armor when you need to, that Defense and the great passives you can get are important, and there are many shops that update their Catalogue selection as time goes on! Go to any shops that sell weapons and clothes and pick up whatever is new, and try to get the special ingredients for those new, more powerful equipment in online play, you won't regret it!
