【FGO】Double Koyanskaya System Compatible Servants Tier List (Pre Oberon Edition)【Fate/Grand Order】

FGO 6th Anniversary brought with it the first Buster Support Servant in FGO with 50% battery charge, and the first Servant with -2 cooldown effect on her skill. Thus, Double Tamamo Vitch/Koyanskaya opened up a new way for AoE Buster Servant to 3T farming via cooldown reset on their battery skill. In this vid I will go over every AoE Buster Servant in the game currently that is compatible with this new method of farming. I will group them into 3 tiers: High Tier: These are outliers/unique cases that perform better than others. 0:00 Altria Saber Note: 20% refund after NP and 30% Battery on 5T cooldown. Requires MLB Kscope, and free to use any Mystic Code. 2:31 Cu Caster Note: Delayed 80% Battery on 5T cooldown. Requires Mage’s Association Uniform Mystic Code, free to use any CE. In this vid I used Black Grail. 4:44 Emiya Archer Note: Can fully refund once by changing his NP to Art for 1 turn. Requires MLB Kscope, Fragment of Year 2004 Mystic Code and 3 enemies in W1. Standard Tier: These are the Servants with the most common requirement to be used with Double Koyanskaya System. They all possess a 50% Battery skill with a cooldown of 7 or less. Requires MLB Kscope and Atlas Academy Uniform Mystic Code (except for Avicebron, which I explained below). 7:00 Mordred Note: 20% refund after NP and 30% Battery on 6T cooldown. 9:20 Ibuki 11:56 Tesla Note: Footage from my friend Awashima, as I don’t have Tesla. 14:07 Ishtar 16:54 Ereshkigal 19:16 Altria Lancer 21:39 Drake 24:10 Avicebron Note: 79.5% Battery on 8T cooldown. Requires MLB Kscope & Mage’s Association Uniform Mystic Code. 26:57 Nero Caster 29:37 Morgan 31:57 BB Summer 34:36 Altria Ruler Note: 20% refund after NP and 40% Battery on 6T cooldown. 37:22 Space Ishtar 40:06 Abby Summer Low Tier: These are the Servants that could not qualify for Standard Tier, but still managed to 3T with the help of Plugsuit and either Waver/Reines/Castoria. The common requirement for this tier is to possess a 30% Battery skill with a cooldown of 5 or less, though there are exceptions. 42:38 Altria Alter Note: 10% refund after NP and 20% Battery on 5T cooldown. 45:06 Gilgamesh 47:47 Melusine Note: requires MLB Prisma Cosmos instead of MLB Kscope. Footage from my friend Leilan, as I don’t have enough materials to max her skills yet. 50:42 Semiramis 53:31 Koyanskaya Note: unfortunately, her own 50% Battery Charge has 8T cooldown, failing to qualify herself for Standard Tier. 56:12 Arjuna Alter Nope Tier: Any other AoE Buster Servant not mentioned above most likely will not able to use their own NP 3 times in a row even with the help of MLB Kscope, Double Koyanskaya and Plugsuit. Advantage of Koyanskaya System: - Enemy comp is irrelevant as long as there are 3 or less enemies per wave. - Thus, it is more suitable for Lv90 farming nodes. Disadvantage of Koyanskaya System: - Lower damage ceiling against non-Human / non-Man trait enemies compared to Skadi & Castoria System. - Many Servants are also stuck with using Atlas MC and cannot use it to boost their W3 damage, further reducing the damage ceiling. - Sequence of skill usage is very important and will need getting used to. Disclaimer: Like always, this tierlist was made mostly according to my own criteria for improving my convenience during farming. Don’t let me tell you how to play the game, adapt and improvise. May the war criminal bunny smiles upon you. #fgo
