With her ability to create any sort of medicine, Eirin can select one out of three types of medicine at the start of the game as purchasable consumables for her and her allies. The items available for purchase are MCLucky Item JadeRabbitIncense Jade Rabbit Incense, MCLucky Item ButterflyDreamPill Butterfly Dream Pill and MCLucky Item HouraiElixir Hourai Elixir.

COOLDOWN: 14 / 13 / 12 / 11 / 10
MCLucky Eirin Q

Active: Eirin targets an enemy and generates a machine directly in front of her that hovers in place, which immediately shoots a pair of beams three times within a second that is angled in proportion to the point of the enemy target is standing so that it barely misses. Each beam deals magic damage to affected enemies and are reduced for every enemy the beam passes, to a minimum of 40% damage.

  • Maximum total magic damage: 120 / 180 / 240 / 300 / 360 (+ 75% AP)
  • Beam speed: 1200

Rising Game
COST: 40 mana per attack
MCLucky Eirin W

Toggle: Eirin's arrows are imbued with life essence, each attack deals bonus damage and the essence returns to Eirin, healing herself and half of that to nearby allies.

  • Heal: 20 / 30 / 40 / 50 / 60 (+ 10% AP)
  • Radius: 250
  • Magic damage: 30 / 55 / 80 / 105 / 130 (+ 30% AP)

Galaxy in a Pot
RANGE: 700
COST: 60 / 70 / 80 / 90 / 100 mana
MCLucky Eirin E

Active: Releases a pseudo-galaxy on the target area that slowly expands outwards and lasts for 5 seconds, dealing magic damage per second to affected enemies. Other non-ultimate abilities have bonus effects while within this galaxy:

  • Omoikane's Device: Beams bounce 2 more times inside the galaxy, re-enabling the beams to damage the same enemies again.
  • Rising Life: When Eirin attacks an enemy inside the galaxy, all allies inside the area also receive the heal from the ability. This can stack with the main heal.

  • Magic damage per second: 30 / 45 / 60 / 75 / 90 (+ 12% AP)
  • Maximum magic damage: 150 / 225 / 300 / 375 / 450 (+ 60% AP)

COST: 100 mana
COOLDOWN: 160 / 140 / 120
MCLucky Eirin R

Active: Fires an extremely fast arrow to the skies that disappears from the map halfway while travelling. A second later, a meteorite or a satellite falls down to the targeted area, dealing magic damage and stuns enemies for 1.25 seconds.

  • Magic damage: 140 / 250 / 360 (+ 80% AP)
  • Radius: 250

Notes and NonsenseEdit

Eirin is a Lunarian, who is also a genius pharmacist, able to manufacture any imaginable medicine within a short time. She is one of the founders of the Lunar Capital and is older than Tsukuyomi, the Moon god. She is the mentor of the two Generals of the Lunar Defense Corps, Yorihime and Toyohime. One of her best (and worst) works is the Hourai Elixir, which gives Immortality, drank by Kaguya, Mokou and Chang'E. Eirin is devoted to her mistress Kaguya and has a servant named Reisen. Personality wise, she's fairly pleasant, but dislikes fools and is rather impatient and condescending if people aren't sharp enough to follow whatever she says. Also, she lacks general common sense as she's not a human being.

"The least of calculations breaks through the highest of space engineering. Should a person wish to break through and develop new technology, it is necessary to abandon it."
Yagokoro Eirin
  • Passive: As a prodigy pharmacist, Eirin's passive allows her team to buy one of her three consumables - Jade Rabbit Incense, which works as a healing sight ward; Butterfly Dream Pill, which gives temporary attack speed and cooldown reduction when consumed; and the Hourai Elixir, which is a rather expensive Guardian Angel item Guardian Angel consumable.
  • Q: Harassment or zoning tool. Do note that this ability will NEVER damage the intended enemy target directly, unless the enemy moves to touch the lasers. The beams can bounce inside Galaxy in a Pot twice before disappearing, otherwise it'll just disappear at maximum range.
  • W: An ability that heals allies when you attack, SionSquare Sion style. If Eirin's attack target is standing inside the galaxy, the entire galaxy acts as a healing medium for her allies.
  • E: AoE damage over time. The damage from this ability isn't important, it's the follow-up that makes this ability high in utility. Lasers bounce twice inside this galaxy and heals applying inside, like a small universe within itself.
  • R: A teamfight-CC ultimate. Originally I wanted to make this a skillshot-skillshot, with the landing range equal to the distance it takes for the arrow to disappear, but it's too complicated and unviable. Needless to say, the lunar magic that crashes a meteorite or a mechanical satellite from the skies - rule of cool. Lore wise: In the year 1969, NASA declared war on the Lunarians as Neil Armstrong plants the American flag, claiming the moon for humans. Expeditions from Apollo 11 to Apollo 17 are actually highly-skilled human assassins sent to remove the top generals. Apollo 13 never managed to reach Moon, because it was shot down by Lunarians, and truth is only known to them.

Eirin supports her allies in a different way, by selling better consumables than the shop offers and a powerful AoE kit with Galaxy in a Pot and Omoikane's Device. Understanding how the lasers reflect in an expanding galaxy and using it to max potential separates the great from the good Eirins. Her toggle is a heal, making her hard to kill without focus, but only works if she attacks. Canonically she is a very powerful being who has existed long before Tsukuyomi is born and her power is very high, but she purposely sets a skill limit on herself, right below Kaguya out of respect.
