Gacha

In the Gacha menu you can use iris or gacha tickets to draw from banners. Occasionally, a free gacha is available allowing you to summon for free.

The usual options are a single pull for 40 iris or an 11-pull for 400 iris. It is highly recommended to only do the 400 iris pulls, as they are effectively 10% discounted AND feature guaranteed units on pulls 1, 4, 7 and 10.

## Banners

By sliding the screen, you can switch to a different banner. There are usually several different banners available. Banners last from a day to several weeks. Some banners are one-time only, others have seen an occasional return (but those are rare). For a list of banners, see the list of banners by time.

Click Gatcha Details button visible on each banner for specific info on what units are available in that banner and at what odds.

### Paid vs regular banners

Paid banners require you to spend paid iris acquired for real money from the [Shop]. They generally guarantee one of a limited selection of 4-star adventurers (often only one, so you have a 100% chance of getting a copy of the unit you want).

Regular banners generally follow the progression of guaranteed unit from a limited pool on 1st, 4th, 7th and 10th. Check the Gatcha Details for whether there is only one unit guaranteed, or several.

Before spending your iris on a paid banner, check the [Purchase] menu for bundles, which may be a bit more cost-efficient, and may include additional perks like in-game resources. For example, a 1000-paid iris bundle often includes 3 guaranteed 4- star units, as well as a "joker" bond and some resources, compared to the usual 400-paid iris pull which guarantees only a single unit. However, the 400-paid iris pull usually guarantees a specific unit, whereas the tickets from the bundles do not, or guarantee a unit from a small pool.

## Rarity

Each rarity of Summon corresponds to their starting tier (and, as such, their initial maximum level). Each version of a character has different stats; in general, Summons obtained at higher tiers have better stats than those summoned at lower ones. Summons are 2-, 3-, or 4-star (you can't summon a 1-, 5- or a 6-star).

For all practical instances and purposes, only 4-star summons are usable, 2- and 3- summons are generally weak and have little use in the long run outside the Dispatch Quests.

## Odds

You can see the odds in the Gatcha Details menu. Generally they are 1% for a 4-star adventurer, and 2% for a 4-star assist, with the remaining 97% being 2- and 3- star garbage.

## Units vs Bonds

Units cannot be sold or destroyed; duplicate summons are transformed into "Bond" items that are used after the corresponding character gets to Lv. 60 and fills their Status Board to perform Limit Break, which can be performed five times, each unlocking five more Status Board Cells and four Levels that must be filled before the next Limit Break is available. Bonds beyond the 5th one are not needed, and should be manually sold in the [Other]→[Inventory]→[Bond] menu.

## Character Pool

Majority of the characters you can summon are the DanMachi franchise (there are also time-limited units from other franchises available during the rare Collab events), and are classified as either Adventurer or Supporter. Adventurers are the ones that fight monsters in the Dungeon; Supporters do not fight, but instead assist the Adventurers in various ways. In MEMORIA FREESE, these are not Supporters in the franchise's definition (those that retrieve Monster drops and carry items such as healing potions), but the manly Gods and Goddesses that Adventurers and Supporters serve, as well as other people that do not enter the dungeon, such as bar maidens. Instead, franchise-definition Supporters are generally placed with the Adventurers.

### Regular vs time-limited units

Units are either regular or time-limited. Time-limited units are only summonable from specific banners, and may never rotate back, whereas regular units are always in the pool. Check Gatcha Details in the banner for whether units in this banner are regular or time limited.

## Tickets

There are several different tickets in the game. Gacha tickets can be spend in the gacha menu to summon characters without spending Iris. The tickets can give you either 1 or an 11 draw, and be either "guaranteed" or not (a "guaranteed" ticket guarantees at least one 3+ or 4+ unit). There also are trade tickets used to trade with a specific item or unit of your choice, this is generally done at [Shop] → [Special Exchange].

Be aware that some tickets expire within a month of being obtained. Use them before they expire. You can check ticket's expiration date in [Other]→[Inventory]→[Consumable]

## Strategy (when to pull)

It is generally recommended to get all the bonds possible for a unit, which requires either spending real money or being moderately lucky with free pulls, usually the full series of 10 pulls. So unless you just want to collect characters and give up on challenging content, it is advisable to roll only when you are ready to spend 4k iris for 10 multi pulls.

It is also recommended to pull primarily during the limited-time banners, and save iris for the game anniversary (which happens around early summer), which often features a number of strong, time-limited units.

If you are a new player and wonder if a unit is worth pulling for or not, join a large DMF discord and ask the question there, or ask it on DMF reddit or such.

Finally, you should also consider the fact that you can get "joker" bonds in the form of prism bond and star bonds. This means that you can LB a unit later - but it is not easy, as you can roughly expect to get maybe one of those joker bonds per month (if you are a F2P, maybe 2-3 if you are P2P).
