Collaboration Characters

## Acquisition

Collaboration characters can be summoned via their respective Event summoning at any time during their collaboration event. Additionally, the last story chapter of the collaboration event grants the player 1 SSR selection ticket, that can be exchanged for 1 of event's respective collaboration characters. Note: These SSR tickets expire about a week after the event end date, so saving them for later is inadvisable.

* Tip: Exhaust all regular event tickets and any Flarelight summoning you wish to do before using the SSR ticket to prevent potentially receiving unwated duplicates.

Event reprints do not provide additional SSR selection tickets.

## Latent Skills/Abilites

All collaboration characters have only 1 dress each. This dress comes with 2 skills and 2 abilities. As such, they can't acquire skills or abilities from other dresses, however their 'latent' skills and abilities can be unlocked by expending 'Dupe Stones' of various rarities. After being unlocked, these skills can be leveled-up by using regular skill-leveling materials. Unlocked abilites however, still require 'Dupe Stones' to level-up, just like other Irises.

Event Reprints tend to add 1 additional latent skill and ability to both event characters.

## Academy

Collaboration Characters cannot participate in the academy training. However, they can still unlock Potentials (passive boosts) by using EXP orbs.

## Weapons

Just like other Irises, Collaboration Characters' R-rarity weapons can be acquired by purchasing it for 5k underworld coins in shop. Keep in mind that it won't show up in the shop unless you possess the respective character. SR-rarity weapon can be acquired as a mission reward for enhancing R-rarity weapon to Lv15. SSR weapons can't be acquired by exchanging 20 Sacred Fragments, but can be be purchased for 2000 Azure Dust instead.

## Expeditions/Trials

Collaboration characters can't participate in Expeditions, but they can still participate in Trials.

## Attribute Change

Collaboration Characters only possess 1 dress of predetermined element. However, their dress Attribute can be temporarily changed by equipping them with exclusive decorations. These decorations can be purchased in the Shop for 2000 Azure Dust each. These decorations don't have an use/equip limit and can be swapped inbetween any of the collaboration characters without restrictions. It's not possible to equip the same decoration on 2 different characters in the same party simultanously however, that will require having 2 copies of that specific decoration.

## Dupe Stones

Collaboration Characters' only dress is of SSR rarity. As a result, they can't use lower rarity Dupe Stones to increase the Level cap of their lower rarity dresses. Instead, their Lower rarity Dupe Stones are used to unlock 'latent' skills and abilities, and level-up said abilities.

Dupe Stones of N, R, SR rarities can be acquired from the event shop during their respective events. Dupe Stones of SSR rarity can be acquired by summoning respective duplicate dresses (N/R/SR stones can't be acquired from summoning duplicates). Other than that, Dupe Stones of all rarities, including SSR can be acquired by purchasing them with Azure Dust for 10/100/400/2000 Dust respectively.
