Worth building if you run Physical/Electric Anomaly DPS (
Jane, 
Yanagi, 
Grace). He's a cheap but high-value A-rank support: shield, AP buff, and RES shred all in one. The weakness is that he only buffs one ally strongly and is less flexible than S-rank supports; outside Anomaly teams he's nearly useless.
Seth converts 40% of his initial ATK into a shield (cap 3,000 pts, 25s), so ATK is the core stat. Level 60 targets (per game8): ATK ~3,750 (ideal) / ~3,200 (comfort minimum). KEY NOTE: the Anomaly Proficiency buff Seth hands allies scales with his Core Skill LEVEL, NOT with his own AP — a maxed Core gives ~+100 AP (gamewith lists ~85 AP at Core Lv4), so you do NOT need to farm AP on Seth (unless playing him as a sub-attacker). Main stats: disc 4 ATK% · disc 5 ATK% · disc 6 ATK% or Energy Regen. Bring some Energy Regen so his EX Special cycles reliably. Substat priority: ATK% > Energy Regen > ATK > PEN (per game8/prydwen).
1) Use EX Special (Thunder Shield Rush) to gain the Shield of Firm Resolve (= 40% ATK) and build Resolve; or catch an enemy attack with Defensive Assist to both block and build Resolve. 2) At Resolve >=75%, HOLD Basic to spend Resolve and unleash the enhanced Basic 'Thunder Strike – Shock'. 3) The combo's finisher triggers a Quick Assist to the agent placed DIRECTLY before Seth (left in party order) → that agent receives a shield + Anomaly Proficiency buff. 4) So put the Anomaly DPS immediately before Seth. 5) Loop: swap back to Seth to refresh shield/buff as needed, but keep his field time short so the DPS holds the field. With M2 you skip the wind-up since Resolve starts at 75%.
The most worthwhile bump for a support: the Shield of Firm Resolve gains +30% strength and the Anomaly Proficiency buff lasts +10s longer → near-permanent buff uptime and a much thicker shield for the DPS. For an enabler, M1 matters more for ease-of-use than almost anything else.
Enter battle with 75% Resolve already filled → you can immediately fire the enhanced Basic and hand a shield + buff to the DPS with no wind-up. A big quality-of-life gain for the per-rotation setup that cuts Seth's on-field time. A sensible second stopping point after M1 (per game8/gamewith).
All skills +2 levels. Only a small bump to buff/shield values (which scale with Core level), no gameplay change — a stepping stone to M4, low value for most players.
Defensive Assist gains +25% Daze/Break value. Mildly useful in teams that want extra stun pressure, but Seth isn't a Stunner so it's just seasoning — not worth pulling for on its own.
All skills +2 levels again. Still just flat numbers, a bridge to M6 — low value.
The final hit of the enhanced Basic combo gets a damage boost and a GUARANTEED crit. It raises Seth's personal damage and suits a sub-attacker playstyle (mono-Electric with an AP build), but since Seth is mainly an enabler this is a whale-tier tick most players don't need.
- A dirt-cheap three-in-one: gives a durable shield, buffs the DPS's Anomaly Proficiency, and lowers enemy resistance — an A-rank support doing S-rank work for Electric/Physical Anomaly teams.
- His AP buff costs him no personal stats: the buff scales off Core level, so Seth only needs to farm ATK for the shield — very easy to build for F2P.
- Shield + Defensive Assist keeps the team alive through heavy burst hits, letting the Anomaly DPS stay on-field continuously instead of dodging or swapping out.
- Refreshing the buff costs no energy, so uptime is easy to hold; flexible across teams from Jane Assault to mono-Electric Yanagi/Grace.
- Only strongly buffs/shields ONE ally (the agent placed before him): not a whole-team support, less flexible than S-rank supports, and demands correct party ordering.
- Nearly dead weight outside Anomaly teams: without an Electric/Physical Anomaly DPS (Jane, Yanagi, Grace, Burnice…) Seth loses most of his value.
- Needs on-field time to build Resolve and set up each rotation; his own damage is low, so sloppy play can burn precious seconds in timed modes.
In Shiyu Defense Seth is a solid backbone for a side running Anomaly DPS (Jane, Yanagi): the shield lets the DPS stay on-field pumping anomaly while keeping the AP buff up. He adds no burst himself, so don't let him eat many seconds; with the right comp he's a timing-friendly A-rank support for F2P. (Inferred from kit + game8's Anomaly-support placement — medium confidence.)
Deadly Assault is where Seth shines most: bosses hit with heavy burst, and shield + Defensive Assist let Disorder teams (Jane Assault, mono-Electric Yanagi/Grace + Rina) hold ground and keep piling anomaly on high-HP targets without constant dodging — often the score-lifting link for Anomaly teams. (Inferred from kit — medium confidence.)
