Shore-spear Fionn — guide

In short

Shore-spear Fionn is a Rare Attack champion from Sylvan Watchers, Dark affinity. He shines in the Sylvan Watchers Faction Crypt (4/5), where he brings the aura, buff stripping and turn-meter control at once, and he is a situational debuffer for Hydra (2.5/5). Build him for Speed and Accuracy first, damage second.

Strengths

• Deadly Thorns hits every enemy twice: the first hit strips one random buff from each target (50%, up to 75% with books), the second applies Decrease SPD 30% for 2 turns (75%, up to 100% with books).
• Undercurrent cuts the target's turn meter by 50% and applies a 50% debuff for 2 turns — 75% base, 100% with books — on a 4-turn cooldown (3 with books).
• Sharp Trident hits twice and removes 5% turn meter per hit on targets under Decrease SPD, so his own A2 feeds his A1.
• Aura: +20% Ally ATK in Faction Crypts.
• Dark affinity means no weak matchups inside the Sylvan Watchers crypt.

Weaknesses

• Thin base stats: 1,387 ATK, 804 DEF and 12,555 HP — he folds quickly in long fights.
• Almost useless on Clan Boss (1/5): no Poison or HP Burn, and his turn-meter control means little against a boss.
• Arena (1.5/5) is rough: 97 base SPD and Rare rarity, with no hard CC before books.
• Every debuff runs through Accuracy, so high-resistance enemies blunt him.

Where to use

By ratings: Faction Crypts first (4/5) — that is his home. Then Hydra (2.5/5) as a budget buff stripper and Decrease SPD spreader, though his damage is minor. Chimera, dungeons, Hard mode and Doom Tower sit at 2/5: Fire Knight's Castle and Astranyx are listed uses, but survivability is what holds him back there. Skip Arena (1.5/5) and Clan Boss (1/5).

Stats and gear

Priority: SPD 200+, ACC 200–250 (150–180 is enough for Faction Crypts), C.RATE 100%, C.DMG 150%+, then HP/DEF. Recommended sets: Speed, Perception, Impulse, Supersonic, Pinpoint, Feral. Relics worth considering: Wand of Submission, Hoarder’s Cauldron, Sempiternal Anchor.

Masteries and blessings

Author's pick: Precision Removal, Unflinching, Gathering Momentum, Slow The Enemy — accuracy and buff removal, plus survivability and damage ramp. Blessings: Phantom Touch for damage, Survival Instinct if he keeps dying, Hero Soul as the middle option.

Tomes

Book Undercurrent first: three tomes give the full 100% chance and take the cooldown from 4 to 3 — the cheapest power spike. Then Deadly Thorns, which needs up to five tomes but drops its cooldown from 5 to 4.

Verdict

A narrow but honest Rare — a genuine Faction Crypt tool, and only a filler controller anywhere else.
