Frost Spire marks exactly 3 Legions. 12 seconds later, an icicle rises under each marked Legion, knocking nearby Legions Airborne.
Twelve seconds is a long time. That is the window in which a marked player walks the icicle to where the raid will need it, and it is why this mechanic gets called out rather than reacted to.
Realm of Rime also grows icicles on its own, but it stops entirely once the Giant drops below 50% HP. From that point on, every piece of cover in the Lair came from a marked player.
Implacable: the Giant destroys any icicle it reaches or hits. So the rule is not only "do not stack icicles" and "leave lanes open". It is do not place icicles where the Giant is walking, or you will have spent your cover on nothing.
Frost Spire
Frost Giant marks 3 Legions. 12s later, an icicle appears under all marked targets, dealing damage to all Legions near it and knocking them Airborne. Skill Damage (Physical). Damage Factor: 100.
Realm of Rime
Frost Giant generates massive icicles in its Lair. Frost Giant stops casting this skill when its remaining HP is below 50%.
Implacable
Frost Giant destroys an icicle upon reaching or hitting it.
My Cave, My Rules: a charge-up, then damage to every Legion in the Lair, knocking everyone Airborne. 50% of maximum Unit Count. The skill text says it plainly: hide behind an icicle to dodge it.
Snowboulder: the Giant marks a Legion standing outside a frozen area and rolls a boulder at them. 100% of maximum Unit Count to everything in its path, and it explodes when it hits an icicle or a wall, hitting everything around that too.
100% of your maximum Unit Count is the entire Legion. This is the single biggest hit in the fight, and again the answer is cover, not distance. Get an icicle between you and the boulder.
My Cave, My Rules
After a short charge-up, Frost Giant deals damage to all enemy Legions in its Lair, knocking them Airborne. Hide behind an icicle to dodge the damage. Skill Damage (Physical). Damage Value: 50% of the Legion's maximum Unit Count.
Snowboulder
Frost Giant marks an enemy Legion outside a frozen area. Moments later, it rolls a snowball toward the marked target, dealing damage to all the Legions in the snowball's path. Skill Damage (Physical). Damage Value: 100% of the Legion's maximum Unit Count. The snowball explodes upon hitting icicles or walls, dealing damage to all surrounding Legions. Hide behind an icicle to dodge the damage. Skill Damage (Physical). Damage Value: 100% of the Legion's maximum Unit Count.
The Giant roars, knocks everyone Airborne out to the edge of the Lair, and creates a frozen area.
That frozen area matters twice: it is where Frost Manastones appear in the second stage, and standing inside one is what keeps you off Snowboulder's target list.
Howling Winds
Frost Giant roars with rage, knocking all enemy Legions Airborne, throwing them to the edge of its Lair and generating 1 frozen area.
The Frost Giant takes 100% less damage. Not reduced, immune. Your DPS does literally nothing until you break it.
Frost Manastones appear inside the frozen areas. Gathering one:
Each Legion can only gather one.
That last line is why the raid needs ten different Legions on stone duty, not ten trips by one fast player. Ten stones, ten Legions, and the immunity is gone.
And each of those ten walks away with +50% ATK for 30 seconds. Send damage dealers, not spare bodies. The stone run and your burst window are the same thirty seconds.
Everyone not collecting stays grouped behind one icicle and moves as a block when it breaks.
Call of the Ancestors
During the second stage, Frost Giant takes 100% less damage.
Healing Manastone appears when the second stage ends. Have the tank pull the Giant away from the pile, then collect. It heals your Legion's lightly wounded units.
Healing Manastone
When the second stage ends, the Lair produces Healing Manastone. When gathered, it heals a Legion's lightly wounded units.
