-You can hire allies of a higher powerlevel at times, but, their helper unit will tuned down to the level of your highest leveled girl from unit 1.
So what people usually do, is level their best girl (in your case Ardisia) as fast as possible. Use at least 2/3rd of the purple manyus you find on her (since you do want your other magic girls to level at least a little bit, to help 3-medal the maps)
-The mid-grade equipment seeds (dropped from raidbosses above lvl 40) is pretty decent. Especially when you level it up a little bit (equipment upgrade tab on the unit screen). The +10 items are pretty hard to find, but those should be the ones you upgrade. Don't upgrade lower quality items (+9 or less) or low-grade equipment more than once, since eventually, you'll want to feed even +9 jewelry to your +10 jewelry. Use rings to upgrade rings, bracelets to upgrade bracelets, etc. Be careful, leveling equipment is as expensive as leveling your girls!
-If you mean the daily missions (they change every day), then yes, but you'll get way less gold from those maps, which is also needed to level your girls.
-For evolving, you need "dragons". We can only get those on monday, tuesday, thursday and friday. Each of those days features a different color dragon. Dragons also come in 3 different qualities for each color.
A 2* girl requires 5 low quality dragons of her color.
A 5* girl requires 3 high quality dragons and 2 mid-quality dragons of her color.
A 6* girl requires 5 high quality dragons of her color.
Evolving also costs a lot of gold, be warned! A 2* costs 50k gold to evolve, a 6* costs 200k to evolve.
-Yes, use that skillbloom on Ardisia, unless you expect to get more 6* soon (very unlikely, unless you pay real money. they're very rare drops from gacha pulls). It will increase the trigger-rate of her special attack (and give a little bit of experience, but not much)
-Favourite gifts only give double the affection, meaning they allow you to reach 100% affection faster, so you can move on to the next girl to give presents to. Just give each type of present only to girls who have it as their favourite, so effectively, you should always have four girls you're giving presents to at the same time.
