If no one has reserved, I could make simple OT for The Alchemist Code when its officially released.
Here are some impressions of units and Limit Breaking + possible pull rate for 5*.
Been browsing Reddit
Alchemist Code and there are some mentions that unofficial 5* rate is 10%, take it with grain of salt. I made one multi pull (500 gems) and got Chloe from there (I didn't reroll when I started).
The rate might be "true", cause later on you need multiple copies of 5* units for Limit Break.
Every copy after first one comes as shards, which one uses for limit break. I think pulling dupe 5* gives 25 shards instead of unit.
You do need alot of dupes (15) to max limit break unit that is 5*.
5* Unit has 5 LB (Limit Break) crystals, to fill all those 5 LB crystals you need 375 unit soul shards.
Logi is 2* story unit you get from start and very good unit. You can farm 3 soul shard per day (from hard 1-1 dungeon named: The Turbulent Beginning, 16 stamina per run) it will take 125 days to get Logi max Limit Break (in 5* form). Iam not sure if there is another dungeon later on story where you can get Logi shards too. For Rin there is 2 dungeons available: Ch 1: Ep 1 [2-5] / Ch 1: Ep 2 [3-2] (so you get 6 shards per day). Rin can be pulled from coin gacha as 1* unit.
These dungeons are always "Hard" dungeons and limited to 3 runs per day per dungeon.
Here are few pics about 4* Logi and his LB.
As you can see Logi level max at the moment is 57. But limiting factor is player level, thus I can get Logi to 42 and then I need more levels. Easiest and best way to get levels is to do daily quests. Story gives 1 rank exp per 1 stamina used, multiplayer is 2 xp / 1sta.
Adv dungeons are very hard and they are available in multiplayer only. You either go by multiplayer coop (4 persons) or you can try to solo it in multiplayer mode (with only one unit). Beginner (Bgn) and Intermediate (Int) can be soloed. So if there is no multiplayer rooms available you can solo Bgn multiplayer and fulfill daily quest (do one multiplayer).
I have evolved Rin to 3* version and used some Soul Shards for LB
Sofar I have had 0 days in 3 weeks play time where my stamina was in timer / empty, always had excess stamina. I think it regens 5 mins per stamina. But if one wants to grind alot you can easily get stamina to 0. Dungeons cost 10/20/30 stamina per run.
If and when you get that 5* unit from pull know that you need more dupes for soul shards

Edit:
Tomorrow there is 4 hours maintenance in Alchemist Code, they add 2 new heroes: Yomi & Vettel, supposedly Yomi is top tier. But JP (
Gamerch) website says Vettel is top tier, so shrug.
