Arbais the Stonethorn is a Mythical Force Support champion and the first Mythical of the Sylvan Watchers faction, a warrior tainted by the corrupted Mistwood Heart Tree. She is a highly versatile dual-form champion: an Arena-grade support in her base form, and a Taunt-driven tank in her rooted alternate form.
Core Strengths & Abilities
Arbiter-Style Speed Support: In base form, her A3 fills the Turn Meters of all allies by 30% and places a 50% Increase Accuracy buff on them for 2 turns — a powerful Arena opener that also relieves accuracy demands on your team's builds.
Strip, Extend & Revive Insurance: Her base-form A2 removes all buffs from enemies, increases the duration of ally buffs, and places Revive On Death on allies — a potent package for Arena, Doom Tower floors, and Hydra. Her A1 adds Block Active Skills, with a Petrification debuff punishing enemies who attack allies under Revive On Death.
Alternate-Form Tanking: After transforming, her A3 places Taunt and Stone Skin on herself while granting all allies two Continuous Heal buffs, redirecting single-target abilities and countering mechanics like The Phantom Shogun's.
Key Weaknesses
Split Identity: Her value is divided across two forms, so she cannot offer her full support package and her tanking package in the same rotation, and she rates noticeably lower in Amius than elsewhere.
Arbais is an elite endgame pick, with top-tier ratings in Arena, Ice Golem, Iron Twins, and Spider, plus strong Hydra and Clan Boss value.
