Heartwood Matriarch

The Matriarch is the only boss who undoes your damage while you deal it. Everything about the fight is built around her healing — and around the Ice Walls she raises, which are the answer to it.

Healing Pulse

• Restores 3% of her max HP, on a 6-second timer
• At most 2 pulses per phase, so she can never heal more than 18% across the whole fight
• Her phases never go backwards — healing cannot push her back into an earlier phase
• The cap is on pulses, not on time: a slow fight does not let her heal more

Ice Wall

• She raises the first wall 3 seconds in, then another every 12 seconds — but only ever one at a time
• A wall is a barrier, not an enemy: it never moves and never deals damage
• It holds 15% of her max HP and stands in front of her, so it takes your shots first
• Break it and her next Healing Pulse is pushed back, and she is left Thawed for 6 seconds (+25% damage taken)
• Walls drop nothing — they are worth breaking for the Thaw window alone

Phases and what she adds

• At 70% health she calls a Rimebound pack — 4 members, or 6 from a Chapter Boss
• At 35% she calls a second, larger pack — 6 members, or 8 from a Chapter Boss
• Below 35% she also works Frozen Roots every 8 seconds, snaring your fire rate for 2 seconds
• Each call fires once, so the fight gets busier but never loops
