oh wow, really nice first draw
newer players start with 6k jewel after clearing tutorial, whereas when the game started we started with 3k, so we had a bad start ...plus, dumb player like me didn't even do the 3k draw in the beginning -_- if i had a start like this, i'd be happy
btw, another thing, try to get your skill level of weapon to at least 6-7 for each before you go any higher for a certain one... don't know if it's the best strat or not, but since you have mixed elements i think it's best for now maybe, just to give a little extra bonus, as you'll be able to go into expert SP quest/raid way sooner than most could.
SR Weapon
1 R weapon - lvl 2 skill, then after that
2 R weapon - lvl 3 skill
3 R weapon - lvl 4 skill
4 R weapon - lvl 5 skill
5 R weapon - lvl 6 skill
6 R weapon - lvl 7 skill
and so on..
SSR Weapon
basically the same, but doubled
2 R weapon - lvl 2 skill
4 R weapon - lvl 3 skill
6 R weapon - lvl 4 skill
8 R weapon - lvl 5 skill
10 R weapon - lvl 6 skill
etc..
but... this is only for 100% which guarantees the weapon will level up. I've had realy bad luck with anything below 90%, you can use less R weapon, but just hope that it still works. you can also use SR weapon which gives a bigger bonus, but you'll need SR weapon for now I guess.
a good soul to go for in the start is billy the kid/granuaile/d'art for their snatch skill, but they aren't the best soul.. just for raid boss, since you get shiny chest almost every time in these battles, snatch will increase the drop rate (SR weapons) of each element depending on which one you join, try to get all 3 of each weapon, for when you have more kami and can set certain element teams. also, the healer soul vivian/cassiopeia/andromeda, is good for starting out, so you'll not die in battles, though you do have sol
good luck with the next draws in gacha, you should post who you find with the SR guaranteed/SR kami guaranteed ticket and the 3k jewel from after completing storyline, watching encounters and doing raid boss for the first time. i wonder if you'll find any other SSR kami/eidolon if you haven't already XD
also, maybe nothing i said is helpful, since i'm basically a newbie too.. i'm not too great at this game
