## What unit to reroll for?

Disclaimer: the meta can change and there is no guarantee this guide will be up to date!. Ask on reddit/discord if you want to double check.

As of Dec 2020, the best is and have been [Foxy Princes] Haurhime due to being a very versatile support unit that fits on pretty much any team. She is very useful fo rnew players and quite useful to experienced players. However, since mid-Dec update, you can also receive a free copy of Haruhime from completing Bell mission 40. You can still reroll for her to get her early and then get a free bond, but you can now also try for another useful unit. For example, you can try to get a unit with a +33% SA charge gain party buff (it's very useful and Haru doesn't have it) - units that provide it include [Twilight Supported] Line, [Determination] Welf or [Golden Feathers] Ray.

## Rerolling

TL;DR: Best way to reroll: run 4+ synced instances on BlueStacks or similar free software, and click through the single unit reroll few zillion times until one of the windows generates the unit you want.

* When you start a game, you'll be given a single free gatcha pull with a "gold ticket", which guarantees a 3-star rarity unit or higher. You can reroll that single pull in-game an infinite amount of times - it takes several seconds to do so. The odds are about 1:40 to get a 4-star, so it takes an average of 2-3 minutes to roll a 4-star. At the very minimum, take a 4-star over a 3-star roll. After you accept your 1-pull unit, you may also be given the opportunity to do more free rolls (depending on in-game events), but there are no further in-game rerolls.
* What to reroll for: ask in the reddit forum or discord or such, meta changes quickly. However, the top-tier units are few, so the odds of rolling them are very low. So if it takes 2-3 minutes to reroll a 4-star from a single pull, and let's say we estimate the best unit(s) to be ~1% of the 4-star pull, you are looking at 200-300m or rerolling to get the "best stuff", on average. At least, if you do it on a single device...
* To decrease the time it takes to reroll, it is recommended to run multiple versions of the game, using software like BlueStacks. You may want to look at the functionality for macros and synchronizing (which means you can click once one screen and click in all open game windows simultaneity; see this guide for more info). Ok, you can also do it on multiple mobile devices, but I think more people have access to PC than to multiple phones/tablets, plus you can't sync non-emulated screens. At least, not easily.
* You'll need to install the game and download some data before you get to the rerolling stage. This can take over one hour, and sometimes several, depending on your connection and the server load. After you create the desired number of Google accounts (don't be too greedy, you need to see the screens, so 4-8 is probably the maximum you need). Make sure each cloned BS instance is logged to a different google account. Noe, the next stage can be done in two ways, either with root or without.
	+ Without root: you just have to install and download the game fresh on each instance (account).
	+ With root: This saves the download time, as you just download on one instance, then clone it. So the way to do it is to clone the desired number of BlueStacks instances, and on all but the first one, delete the file bn-payment\_gamelib.xml in the [file system root]/data/data/com.us.danmemo/shared\_prefs (you'll need to enable root access in the BlueStacks - that is access to the root directory in BlueStacks settings, this requires rooting BlueStacks. I used BSTweaker tool. Guides for rooting BS using BST: here, here and here). Then go to BS settings>advanced>scroll down and enable root access. This can seem more complicated, and it is, but it will allow you to potentially run the game on PC and a mobile device later (see my other guide). Your call, you can always root stuff later for using two devices, this is not needed for rerolling. To access the file structure, I use a free file browsing soft called Total Commander, there are other options if you have a preference, shrug.
* You'll need to run through the tutorial on each account before you get to the rerolling part. You might as well do it simultaneously using the sync option in BlueStacks (it means that you click on one screen, and that click and your cursor movements are duplicated on all other instances). So wait for all instances to download, then launch them at the same time and sync.
	+ I wrote a BlueStacks macro you can download from the BlueStacks macro community, just search for memoria freese and you will see it.
* After about half an hour of rerolling, the game may start getting laggy, which will affect sync issues. It is best to restart the game on all instances so that they run smoothly again (and are in sync).
* Once you get the desired unit on one account, disable sync in BlueStacks, save your good account (go to game settings/other, click import, connect it to Facebook and/or make a password and screenshot your ID transfer number). Then make sure to use the correct account on your future main device(s).

Rerolling is likely not considered cheating, in case you wonder about the chance of getting banned for this (1, 2, 3).

Final note: the game doesn't support running the same account on multiple devices, officially. But just like the above trick for running multiple accounts under one Google ID for rerolling, you can also easily migrate an account from Bluestacks to single mobile device and vice versa. See the multiple instances guide for more.
