Strategos Islin — guide

In short

Strategos Islin is a Legendary High Elves defense champion who wins through shields, a Defense buff and Provoke rather than damage. He shines in Clan Boss, Hydra, Arena and Faction Wars, where his passive heals the whole team standing under his Ally Shield. Build priority is Defense and Speed — crit stats are wasted on him.

Strengths

• His A3 gives the team Ally Shield 50% and a 60% Defense buff for 2 turns in one press, plus Counterattack and a Shield on himself.
• Passive: when hit, he heals himself for 1% per 500 Defense and heals allies under his Ally Shield for 30% of that heal — free sustain.
• A1 hits twice and Provokes for 1 turn with a 50% chance (75% on a counterattack).
• A2 strips buff duration and drops a 30% Decrease SPD for 2 turns on the entire enemy team.
• Aura of +60 Accuracy in all battles — universally useful and great for the team's debuffers.

Weaknesses

• Slow: 102 Speed at 6★, so he needs Speed gear to take turns.
• Almost no damage — A1 and A2 scale off Defense but with modest multipliers.
• Ally Shield goes on allies, not on himself: strip it or land Block Buffs and the passive heal to the team is gone.
• In Dungeons, Doom Tower and Hard mode (3.0) he loses to dedicated tanks and healers.

Where to use

Faction Wars (4.5) is his best home — aura, shields and healing cover nearly the whole faction. Clan Boss, Hydra and Arena (4.0 each) are also his territory: Defense buff, Provoke and Decrease SPD all matter there. Chimera (3.5) is workable but other champions do more. Dungeons, Hard and Doom Tower (3.0 each) — only if you specifically need a Provoke tank.

Stats and gear

Priority: Defense → Speed → HP → Accuracy → Resistance. Targets: DEF 3000–3500 (shields, heals and damage all scale from it), SPD 200–230, HP 40,000+, Accuracy 150–200 (the aura gives +60, so gear can be lighter), Resistance 300+ against debuff teams. Ignore C.RATE and C.DMG.

Sets: Regeneration (the main one — passive plus regen keep him alive), Perception, Guardian, Protection, Bolster, Defiant. Relic: Blades of Akumori.

Masteries and blessings

Trees: Defense and Support. Key picks are Damage Mitigation and Bolstered Defense for survival, Invigorated and Gathering Momentum for healing and ramp, Expeditious Exploitation and Buff Depletion for turn flow and debuff pressure.

Blessings: Faultless defense is the default for a tank; Miracle Heal if you want extra healing; Polymorph against Arena control; Brimstone if you want a bit of damage.

Tomes

Book his A3 first: levels 2 and 3 each cut 1 turn of cooldown, taking it from 6 to 4 — that massively raises uptime on the shields and the Defense buff. Then A2, where books add +10% and +15% debuff chance and −1 turn cooldown at the last level. Leave A1 for last.

Verdict

A solid Legendary tank-support for Clan Boss, Hydra, Arena and Faction Wars, and a situational pick in dungeons and Hard mode. Gear him for Defense and Speed and he pays you back.
