Increases your defense, freezes and damages enemies that hit you.
Shiver Armor is a Sorceress Cold buff (level 12, requires Ice Blast and Frozen Armor) and the prerequisite of Chilling Armor. While it is up it adds a percentage to your defense, +159% at level 20, and any enemy that swings at you in melee takes cold damage, 79–90 at level 20, and is chilled for 20 seconds. It costs a flat 11 mana and can be cast in town.

Duration is read at 0 points in Frozen Armor and Chilling Armor.
The defense bonus is the aura's stat skill_armor_percent with aurastatcalc1 ln12: Param1 45 (the table's "Armor % baseline") plus Param2 6 a level ("Armor % per level"): 99% at level 10, 159% at level 20, 219% at level
The damage comes from EMin 12 and EMax 16 with HitShift 7, which halves them: 6–8 at level 1. The minimum then grows +3 a level to level 8, +4 to 16, +5 to 22, +6 to 28 and +7 past that; the maximum grows +3.5, +4.5, +5.5, +6.5 and +7.5 over the same brackets. That is 35–41 at level 10, 79–90 at level 20, 139–155 at level 30.
The cold length is ELen 100 frames with no growth to level 8 (ELevLen1 is empty), then ELevLen2 25 a level to 16 and ELevLen3 50 a level past that: 4 seconds up to level 8, 6 at level 10, 12 at level 16, 20 at level 20, 40 at level 30. The Basin's page lists a fixed 100 frames for its era; the current table grows it.
Duration is ln34: Param3 3,600 frames plus Param4 300 a level, at 25 frames a second: 144 seconds at level 1, 12 more a level, 372 at level 20, plus Param7 250 frames, 10 seconds, for each hard point in Frozen Armor or Chilling Armor. The defense, damage, cold length and base duration read lvl, so +skills count; the synergy seconds read blvl. Mana is 11 at every level and is left out of the table.
Shiver Armor puts the state "shiverarmor" on the Sorceress for its duration and listens for the event attackedinmelee. The Basin's page gives the rule that sets it apart from Frozen Armor: it applies its cold damage and cold length to any hostile unit that executes a melee attack on the Sorceress, whether or not that attack succeeds. A missile triggers nothing; that is Chilling Armor's event. The damage is cold, reduced by the attacker's cold resistance, see Dealing Elemental Damage; it needs no attack roll of its own.
The chill slows the attacker for the cold length, by the monster's own cold-effect figure, divided by the difficulty's cold divisor in Nightmare and Hell, see Chill and Freeze. The Basin's page adds: the skill level is applied only when cast, but +% Cold Skill Damage is applied whenever the cold damage is dealt, so a Cold Mastery or a +% cold skill damage item equipped after the cast still counts. The armor can only apply to the Sorceress and can be active at the same time as Cyclone Armor and Blade Shield but not with Bone Armor, Frozen Armor or Chilling Armor, where the last one cast is active.
The armor does not stop the hit that triggers it; the defense bonus is what lowers the chance to hit, and the damage is paid back, not prevented.
blvl, hard points only).lvl); the synergy percentages and seconds do not move with +skills.A player's hit on another player is cut to 17% of its value (difficultylevels.txt PlayerDamagePercentVSPlayer) before anything else, see Player versus Player; the armor's cold damage on a player who swings at you is cut the same way. The Basin's page gives no other rule for Shiver Armor against players.
