Geirrhafa has 3,700 health and spawns in the mountains.
It takes extra damage from fire; frost does nothing to it at all. Blunt, slash and pierce land at full damage, so that is what to bring.
Its hardest hit is fenring attack iceclaw at 70 frost and 60 slash, out of 4 attacks.
Some of what it throws is elemental, so frost resistance is worth having.
You cannot block fenring attack frost, so give yourself room to dodge instead.
Of everything craftable,
Thunderblood Crossbow,
Lightning Strike and
Staff of Embers put the most damage through what it resists.
It always drops
Hildir's Silver Chest and
Geirrhafa Trophy.
Geirrhafa is a white-furred Cultist miniboss found in the Howling Caverns in the Mountains, holding the second of Hildir's quest chests. He has 3,700 health, is immune to frost and weak to fire, and always drops both
Hildir's Silver Chest and the
Geirrhafa Trophy. He claws for 40 slash and 60 frost every 2 seconds, doubles into two hits of 60 slash and 70 frost on a 10 second cooldown, and breathes an unblockable 100 frost cone from 2 to 6 meters. Every 15 seconds he slams the ground for three expanding shockwaves of 90 frost each that can be neither blocked nor dodged, which makes the fight about footwork rather than the shield.
Everything the cultist does with fire, he does with frost, including a triple shockwave nova that cannot be blocked or dodged: sprint out of its rings instead. He is weak to fire, immune to frost, and the frost cone shuts off if you stand point-blank. Fight in his face or far away, never in between.
With devcommands enabled, this spawns Geirrhafa in front of you. The third number is the level: 3 spawns a 2-star.
