Route and lanes

Castle Blackburn opening view: skull markers on the left, a swamp in the lower left, and the road crossing the yard to the castle wall on the right Source: community creator Let’s Play, “Castle Blackburn - Impossible 3 Stars (Free Only)”, 0:26.

  • Entries: the left edge (skull markers).
  • Middle: the road crosses an open yard with plots on the grass islands, passing a swamp in the lower left.
  • Exits: the glowing markers along the castle wall on the right.
  • Lord Blackburn turns up on his stage before the last fight too, so don’t be surprised when his bar shows mid-run.

Impossible: tower placement (free towers only)

Step When What and where
1 Opening Gold Prospectors, upgraded to IV for income
2 Early waves Sunray Master on the yard plots, upgraded to IV
3 Early-mid Archer Garrison on the grass islands, taken up to IV
4 Mid-run Elven Elite Ranger, upgraded to IV
5 Late Royal Catapult on the remaining plots, upgraded to III

Mid-run: towers on the grass islands in the middle of the yard Source: same video, 8:40.

  • Keep Zefira and Connor near the left entries, where the road first reaches the yard.
  • Royal Edict, Rain of Fire and Reinforcements were all used.

Impossible: boss — Lord Blackburn

Lord Blackburn fight: the health bar at the top reads Lord Blackburn while he stands in the middle of the yard Source: same video, 18:20.

  1. Finish every upgrade before the last wave.
  2. He fights in the middle of the yard, so the island towers keep him in range.
  3. Block him with the heroes and reinforcements, then drop Rain of Fire.

Normal mode

A shorter Normal-mode clip shows a different lineup on the same map.

Field Normal run
Heroes Malik, Bolin
Towers seen Wildcat Huntresses, Scholar Mage (at IV), Sunray Master (at IV)
Spell seen Ace Musketeers

Normal mode: the Lord Blackburn health bar at the top while mages and huntresses fire across the yard Source: Ivailo Tanev, “Kingdom Rush 6: Genesis, Fifth Boss: Lord Blackburn, Normal Difficulty”, 0:40.

  • The clip opens with the defense already built. Scholar Mages do the heavy lifting against Lord Blackburn, and Ace Musketeers adds extra fire.
  • The same yard plots used on Impossible work here too.
