Kingdom Rush 6 Impossible difficulty

Broom · Transformed by Nivus

In stage 6, Nivus transforms up to 5 enemies into Brooms for 10 seconds before they revert. A Broom retains 60% of the original enemy's current and maximum health, has speed 20 (22 on Impossible), and drops the original enemy's gold reward when defeated.

Crowcaller · Periodically summons crows

Every 6 seconds, it summons 1 Crow (2 on Impossible), capping at 10 Crows on the battlefield at once, and stops summoning once near the exit; summoned Crows yield no gold.

Dark Disciple · Binds and disables towers

It flings its grimoire at a nearby tower (within 240, or 300 on Impossible), binding it so the tower is unable to attack until either the Dark Disciple dies or it gets farther than 240 (300 on Impossible) away.

Dark Slayer · Chance to instakill player units

Every 10 seconds, it has a 30% chance (40% on Impossible) to instantly kill the soldier it is fighting; heroes are immune to this.

Frost Brute · Freezes units with its breath

Every 35 seconds (16 on Impossible), if a unit is within a radius of 110, it breathes frost on units within a radius of 110, dealing 20-30 physical damage every 0.5 seconds for 1 second and freezing them for 6 seconds.

Frost Herald · Casts icicles over units

Every 15 seconds (10 on Impossible), it drops 4 rows of 3 icicles onto units 50 to 150 away, each icicle dealing 20-40 magic damage within a radius of 25.

Gargoyle · When near death, it turns into stone and heals

One time only, when its health would drop below 60, including from a lethal hit (unless killed outright or eaten), it instead survives at 60 health, petrifies, and recovers 7.5 health every 0.25 seconds for 4 seconds (6 on Impossible).

Headhunter · Instakills enemies at low health

Every 6 seconds, it instantly kills the unit it is engaged with if that unit's health is at or below 25% (40% on Impossible).

Orc Shaman · Heals enemy units

Every 8 seconds, if at least 2 enemies within a radius of 100 have fallen below 70% health, it conjures a healing aura with a radius of 100 lasting 1 second, restoring 60-80 health per second (135-180 on Impossible) to enemies inside it.

Shadow Blades · Near death, throws smoke bombs that hide enemies

If its health drops below 20% while away from the exit, it hurls a smoke bomb and disappears from combat; for 3 seconds (5 on Impossible), enemies within the smoke's radius of 60 evade every attack.

Spider Matriarch · Lays eggs that hatch Spiderlings after a few seconds

Every 6 seconds, it deposits an egg on the path (no more than 4 eggs at once), never near the exit; every egg hatches after 5 seconds into 3 Spiderlings (4 on Impossible), which grant no gold.

Tainted Wolf · Dodges attacks

It can dodge each melee attack with a 40% chance (55% on Impossible).

Troll Chieftain · Increases nearby trolls' speed and damage

Every 20 seconds (14 on Impossible), if at least 3 enemies are within a radius of 100, it beats its war drum, causing those enemies to deal 1.33x damage and move at 1.33x speed for 8 seconds; the effect applies to any enemy in range, not just trolls.

Troll Crusher · Stuns nearby towers

Every 30 seconds (20 on Impossible), it pounds the ground, dealing 40-60 physical damage to units within a radius of 70 and stunning towers within a radius of 150 for 6 seconds.

Vez'nan · His arrival

Upon his arrival, soldiers are instantly killed (summons that cannot be instantly killed survive), heroes get stunned for 14 seconds, and he restores to his full health of 5,999 / 6,999 / 7,999 / 9,999 on Casual / Normal / Veteran / Impossible.
