Increases your defense and freezes enemies that hit you.
Frozen Armor is a Sorceress Cold buff (level 1, no prerequisite) and the prerequisite of Shiver Armor. While it is up it adds a percentage to your defense, +125% at level 20, and any enemy whose melee attack damages you is frozen for a length that starts at 1.2 seconds. It costs a flat 7 mana and can be cast in town.

Duration is read at 0 points in Shiver Armor and Chilling Armor. Freeze Length is read at 0 points in Shiver Armor and Chilling Armor.
The defense bonus is the aura's stat skill_armor_percent with aurastatcalc1 ln12: Param1 30 (the table's "Armor % baseline") plus Param2 5 a level ("Armor % per level"): 75% at level 10, 125% at level 20, 175% at level
Duration is ln34: Param3 3,600 frames ("Buff Duration") plus Param4 300 a level ("Buff Duration per level"), at 25 frames a second: 144 seconds at level 1, 12 more a level, 372 at level 20. Each hard point in Shiver Armor or Chilling Armor adds Param7 250 frames, 10 seconds, on top.
The freeze length is calc1: ln56, Param5 30 frames ("Freeze Length baseline") plus Param6 3 a level ("Freeze Length per level"), so 1.2 seconds at level 1 and 0.12 more a level, 2.28 at level 10, 3.48 at level 20; then multiplied by 100 plus Param8 5% for each hard point in Shiver Armor and Chilling Armor. The table above shows the lengths with no points in those two skills.
All three lines read lvl for the Sorceress's own level, so +skills count, and blvl for the synergies. Mana is 7 at every level (mana 7, lvlmana 0) and is left out of the table.
Frozen Armor puts the state "frozenarmor" on the Sorceress for its duration (auralencalc ln34 plus the synergy seconds) and listens for one event, damagedinmelee: the Basin's page says it applies its freeze length to any hostile target that executes a successful melee attack which damages the Sorceress. A missed swing triggers nothing, and a missile triggers nothing; those are Shiver Armor's and Chilling Armor's events. There is no damage, so there is no resistance roll and nothing for a mastery to multiply.
The freeze holds the attacker in place for the length, divided by the difficulty's freeze divisor in Nightmare and Hell, see Chill and Freeze. The Basin's page adds: the skill level is set when cast, the armor can only apply to the Sorceress, and it can be active at the same time as Cyclone Armor and Blade Shield but not with Bone Armor, Shiver Armor or Chilling Armor, where the last one cast is active.
Only one of the three armors is up at a time: casting Shiver Armor or Chilling Armor replaces this one.
blvl, hard points only).lvl); the synergy percentages and seconds do not move with +skills.Frozen Armor never deals damage, so the player-versus-player rule has nothing to cut, see Player versus Player. The Basin's page gives no separate rule for the freeze against a player, so nothing more is stated here.
Written from the game's tables (build 3.3.93847) and the cited pages; a per-level table is computed from skills.txt and skilldesc.txt by the same evaluator the skill pages use. A “legacy rule” is a published engine rule no table proves; a “game table” is read from the table named. · Report incorrect data
