Archer — Trailblazer (Ice) + Hanya (F2P)
Free-to-play friendly Archer core. Any two supports can work with Archer, but Remembrance Trailblazer (Ice) + Hanya are the best F2P picks because they provide turn-advance and SP generation. Turn-advance supports should target ~160 SPD to reliably get Archer earlier in the turn order.
Archer — Sparkle + Permansor Terrae
Sparkle is Archer's best support because she provides both Skill Points and turn-advance. Archer benefits from SP-positive sustains (Permansor Terrae, Gallagher, Aventurine, Luocha) to offset his heavy SP consumption. Ensure turn-advance supports reach ~160 SPD to reliably move Archer earlier in the order.

After Archer's teammates attack enemy targets, Archer consumes 1 Charge and immediately launches Follow-Up ATK on the primary target, dealing Quantum DMG equal to 1% of Archer's ATK and recovering 1 Skill Point. If the target is defeated before this Follow-Up ATK is launched, the Follow-Up ATK will be directed at one random enemy instead.
