Recommended Meta Build

Open in Build Planner
Commander
Ruadh Stonecrusher
Weapon
Wallace's Great Claymore / Heavy Warhammer
Clan Affiliation
MacGregor Clan (with Hogg Holy Smite)
Core Dragon Tear Emblems:
💎 Siege Crusher III💎 Smite Vortex II💎 Demolition Quake💎 Unyielding Poise

Build Strategy: Use Ruadh's massive poise and Hogg Vortex to vacuum the 90 reinforcement troops onto Harold's tail, generating infinite Special meter to spam devastating demolition smashes on his head.

Highland Army Squad Tactics

Command 30 Scottish Heavy Shield Infantry to hold the central line against English sword troops, while assigning 2 companion heroes to man the fortress Ballistas to break Harold's chest armor.

4-Player Co-op Coordination

In 4-player co-op, 2 players stay at flanks to bait Fire Breath while 1 player operates the siege engine and 1 support player uses Hogg Vortex to clean minions. During the 3s stun, all 4 unleash ultimate abilities simultaneously.

Boss Tactical Weaknesses
Huge blind spot under belly and flanks during 15-range Fire Breath
Allied Ballista harpoons deal massive poise damage to dragon scale plates
High vulnerability to Hogg Clan Holy Smite Vortex pulling in the 90 add troops
