Ambassador Lethelin — guide

In short

Ambassador Lethelin is an epic High Elves Support with Force affinity. His signature is Banner of Unity — Taunt on an ally plus 30% Reflect Damage for the whole team — so he shines in Faction Wars and on arena defense. Build HP%, DEF% and SPD; damage stats are wasted on him.

Strengths

• Banner of Unity places Taunt on a chosen ally and gives the team 30% Reflect Damage for 2 turns, redirecting single-target hits and punishing attackers.
• Field Medic heals the whole team for 5% of max HP and shortens two random debuffs on each ally, adding another 2.5% healing per debuff shortened.
• His A1 hits all enemies and can drop their C.RATE by 30% for 2 turns, with the chance rising to 55% while he is at full HP — handy against crit-heavy waves.
• Epic rarity: cheap to book, and close to mandatory for High Elves Faction Wars (4.0/5).

Weaknesses

• Base 106 SPD and only 1,189 DEF — slow and squishy until you gear him properly.
• Both utility skills sit on 6-turn cooldowns and feel clunky without books.
• He shortens debuffs but does not cleanse, does not revive and does not strip buffs; his heals are small percentages of max HP.
• Falls off in the hardest content (2.0): debuffs and burst outscale his healing there.

Where to use

Start with Faction Wars (4.0) — that is his home. Next is arena (3.5) as a defensive support core with Taunt and reflect damage. Dungeons and Chimera (3.0) work as a safety net healer. Clan Boss, Hydra and Doom Tower (2.5) are situational only. Skip hard content (2.0). The author also lists Shogun Akumori as a place he gets used.

Stats and gear

Priority: HP% ≈ DEF% (his base DEF is low, so patch it), then SPD, then RES. Rough targets: SPD 200–240, HP 60,000–70,000, DEF 2,500–3,000, RES 200+ for arena and Doom Tower. ACC 100–150 only if you actually want the A1 debuff to land. Recommended sets: Curing, Guardian, Protection, Bolster, Defiant — usually one of Guardian/Protection/Bolster plus Curing.

Masteries and blessings

Go Support and Defense trees; key picks from the list are Blessed Heal, Survival Speed, Revival Blessing, Heal 'N' Go and Revival's Boon. Blessings: Survival instinct as the default, Heavencast as the alternative. Relics: Harp of Kasbiel, Perched Shadow.

Tombs

Book Field Medic (skill 3) first: levels 5–6 cut the cooldown from 6 to 4 turns, so you get the team heal and debuff shortening every 4 turns. Then finish Banner of Unity down to 4 turns. The A1 comes last — books there only add debuff chance.

Verdict

A narrow but solid support for Faction Wars and arena defense; Taunt plus reflect damage does real work. There is no reason to bring him into endgame PvE.
