Grandmaster — guide

In short

Grandmaster is a Rare Banner Lords champion with the HP role and Magic affinity. Every one of his skills scales off ATK, so he is neither a damage dealer nor a real tank — his value is the Provoke on his A3, the Attack Down on his A2 and a +17% HP aura for Magic allies. Build him for Speed and Accuracy, not for damage.

Strengths

• Decay — 50% chance (up to 65% with books) to place Provoke for 1 turn, pulling enemy focus off your key champions.
• Cold Steel — 25% Attack Down for 2 turns, which cuts incoming damage on waves and against the Clan Boss.
• Aura: +17% HP to Magic allies in all battles — free value in a Magic-heavy Faction Wars team.
• Heavy Blows — three hits on the A1, so more procs for your team's on-hit effects.

Weaknesses

• All damage scales from ATK while his role is HP and his bases are low: no damage, no real tanking.
• Provoke lasts one turn, is not guaranteed, and bosses ignore it entirely.
• Brings nothing to the team beyond the aura — no shields, no heals, no buffs.
• 1 057 DEF next to 16 185 HP is thin for a front-line body.

Where to use

His best (still weak) scores are Faction Wars (2/5) and Clan Boss (2/5, and only early, purely for Attack Down). Arena, dungeons, Doom Tower, Hydra, Chimera and Hard mode sit at 1/5 — any real support does the job better.

Stats and gear

Priority: about 170–190 SPD, 150–180 ACC so his A2 and A3 debuffs actually land, then HP% and DEF%. Skip C.RATE and C.DMG — he will not deal damage either way. The build list gives no sets, only a mastery and a relic, so go with HP, Defense, Perception or Speed; the site author also recommends health and defense gear.

Masteries and blessings

The build specifies the Puppetmaster mastery and the Mask of Rage relic. Beyond that, take the usual support-tank route: Support tree for Accuracy and Defense tree for survivability, so Provoke and Attack Down stay up. No blessing is listed — on a Rare it is not a priority.

Tombs

Book Decay first: +15% chance to Provoke (up to 65%), then -1 cooldown — it is his only real tool. Then Cold Steel for the -1 cooldown so Attack Down is up more often. Leave the A1 alone.

Verdict

Into the Vault: keep him as fusion material, or as a last-resort Faction Wars filler if you have nobody else.
