Archer is a Quantum Hunt single-target damage dealer from the Fate collab. In Circuit Connection he can fire his Skill up to 5 times in the same turn, each shot hitting harder than the last, in exchange for a huge Skill Point budget; his Follow-Up ATKs and Rin Tohsaka's Joint ATK refund SP. He is free to claim (instead of Gilgamesh) until the end of version 4.6, and remains one of the strongest damage dealers in every mode.
Main DPS
Light Cones
The Hell Where Ideals Burn BiS
5★
Signature and most consistent option: CRIT Rate, +40% ATK (his A2 raises the SP limit to 6+), then +10% ATK per Skill used (up to 4 stacks).
CRIT Rate +16%; ATK +40% if the Skill Point limit is 6 or more, and +10% ATK per Skill use (up to 4 stacks).
The Finale of a Lie
5★
Ashveil's signature can even beat it next to Rin: her Joint ATK makes the 4 Follow-Up ATKs easy to reach, for +40% ATK, CRIT Rate and +20% DMG taken on all enemies.
CRIT Rate +18%; at the start of battle and every 4 Follow-Up ATKs, gains Umbra Devourer: ATK +40% and all enemies take 20% more DMG for 3 turns.
Baptism of Pure Thought
5★
Dr. Ratio's signature: strong in debuff-heavy teams (3 debuffs on the target).
CRIT DMG +20%, +8% more per debuff on the target (up to 3), and the Ultimate grants +36% DMG and lets Follow-Up ATKs ignore 24% DEF for 2 turns.
Worrisome, Blissful
5★
Topaz's signature: CRIT Rate and a CRIT DMG debuff through his Follow-Up ATKs.
CRIT Rate +18% and Follow-Up ATK DMG +30%; Follow-Up ATKs apply Tame, raising allies' CRIT DMG against the target by 12% per stack (up to 2).
Cruising in the Stellar Sea
5★
Best free option (Herta's Store): CRIT Rate, and ATK after each kill. Its conditional CRIT Rate is a bit awkward to build around.
CRIT Rate +8% (+8% more against enemies at 50% HP or less), and defeating an enemy grants +20% ATK for 2 turns.
See You at the End
4★
Battle Pass 4★: always-on CRIT DMG plus Skill and Follow-Up ATK DMG — the most consistent budget choice.
CRIT DMG +24%, and Skill and Follow-Up ATK DMG +24%.

Teams
Recommended teams
Master and Servant
The best and most used Archer team: Rin shares +150% ATK and 15% Quantum RES PEN, Sparkle raises the SP limit again and refills SP, and Permansor Terrae shields while buffing.
Sustainless
Maximum damage: Tribbie adds RES PEN and Vulnerability. Riskier, but very fast clears.
Without Rin
Accessible core: the free Remembrance Trailblazer's True DMG bonus is maxed out by his 220 Max Energy.
Guide
How to play
How he works
- Caladbolg II: Fake Spiral Sword (Skill). Each shot deals 360% ATK to one enemy and costs 2 Skill Points. It puts him in Circuit Connection: his turn doesn't end, and each shot adds +100% Skill DMG (up to 2 stacks). He can fire up to 5 times; Circuit Connection ends after the 5th shot, when you can't afford another one, or when the wave is cleared. Every shot grants the full Skill Energy and Toughness damage.
- Mind's Eye (True) (Talent). After a teammate attacks, he spends 1 Charge on a 200% ATK Follow-Up ATK that recovers 1 Skill Point — even in the middle of Circuit Connection.
- Unlimited Blade Works (Ultimate, 220 Energy). A 1000% ATK single-target nuke that grants 2 Charges (max 4).
- Traces. A2 (Projection Magecraft): +2 Skill Point limit. A4 (Hero of Justice): 1 Charge when entering combat. A6 (Guardian): whenever allies gain a Skill Point while the team has 4 or more, he gains +120% CRIT DMG for 1 turn.
Rotation
- Use his Technique: it attacks immediately, deals 200% ATK to all enemies and grants 1 Charge.
- Let the team build Skill Points, and start his turn with as many SP as possible and Guardian's CRIT DMG active.
- The first two shots are weaker (+0% and +100%); shots 3 to 5 get +200%. If you can't reach the third shot, use a Basic ATK instead and save the SP for next time.
- Fire Unlimited Blade Works at the priority target; its 2 Charges turn into SP through Follow-Up ATKs.
Tips
- With Rin Tohsaka, her Joint ATK triggers when one of his shots leaves the team at 3 SP or less (or after the 5th shot) and restores 4 SP: make sure she acts between each of his turns.
- Use the weak first shots on adds, or ramp up on the boss before deleting a strong enemy — you can change target between shots.
- He doesn't need SPD: Sparkle drags him through the turn order.
Strengths
- Astounding single-target damage
- Up to 5 Skills per turn, each one stronger
- Very high Toughness damage and Energy generation
- Flexible team building, now with a dedicated partner in Rin Tohsaka
- Free to claim until the end of version 4.6 (choice between him and Gilgamesh)
Weaknesses
- Devours Skill Points: he wants SP supports and a higher SP limit
- Purely single-target without Rin
- Shot order and target choice matter a lot for optimal damage
