[Experimental Studies on Subject A] Agnes Tachyon

SR Intelligence

Analysis

Tier B. A solid budget Wit SR with a real Friendship Bonus and a hint-frequency unique, but it’s fighting for a slot the meta Wit SSRs already own.

Tachyon plays the friendship and skill-point lane instead of trying to stat-check anyone. The bond numbers are good for an SR: Friendship Bonus maxes at 20% and Mood Effect at 40%, so a Wit appearance stays worth rainbowing. The unique kicks in at Lv25 with a flat Skill Point +1 and Hint Frequency +20. That last one matters. Her four green hints (Up-Tempo, Medium Straightaways, Medium Corners, Tether) actually proc often enough to learn on the cheap.

The stat side is where she folds. Wit Bonus 1 and Training Effectiveness 5% mean per-session gains never get close to a tuned Wit SSR. Initial Wit +20 and a 25 starting bond gauge help your early setup and not much past that. Specialty Priority 50 at least keeps her glued to the Wit deck.

Build her if you run Wit and have no SSR there. SP and hint density carry the slot.
Don’t pull for her on purpose. She’s a gacha SR you’ll stack copies of anyway.
Best on uma with deep skill kits, since the SP and hint boosts compound.

She earns her keep as filler and outpaces most SRs on skill points. The moment your Wit SSR shows up, though, she’s riding the bench.
