Magically enhances your arrows or bolts by adding cold damage and a slowing effect. Cold arrows only do half of their regular damage.
Cold Arrow is a level 6 Amazon skill (Bow and Crossbow tree, no prerequisite; it unlocks Ice Arrow and Guided Arrow). It adds cold damage and a chill to a normal arrow and converts a share of the hit to cold. The numbers that decide it are the cold length, 4 seconds at level 1 and +1.2 a level, and the cold range, 53–56 at level 20.

edln ÷25: 4 seconds at level 1, 26.8 at level 20.3+(lvl-1)*2: 41% at level 20. The Basin gives it as min(1 + 2 × slvl, 100).All of the tooltip lines read lvl; only the synergy reads hard points.
Cold Arrow is a missile (srvmissile coldarrow) that needs the attack-rating check, see Chance to Hit, can be blocked, carries 100% of weapon damage (SrcDam 128) and fires at the normal attack's rate (Attack Speed). A hit chills the target for the cold length, see Chill and Freeze; the Basin's page adds that cold length from the weapon's own Cold Damage is added to the skill's.
The game text's "half of their regular damage" is not a penalty. The Basin's page states there is no such reduction, and the table's SrcDam is the full 128.
The Basin's page gives the order of the conversion: after +% damage and a Deadly Strike or Critical Strike doubling, before resistance, so the converted part ignores physical resistance and is reduced by Cold Resist instead, see Dealing Elemental Damage. The Ice Arrow synergy applies only to the skill's own cold range, not to the converted part, and Cold Skill Damage from items likewise applies to the added cold damage but not to converted or weapon cold damage. The same page notes the arrow has half the range of a normal arrow: it can only reach targets within about 14 2/3 yards.
One synergy line: Ice Arrow, +12% cold damage per level, from EDmgSymPerCalc = skill('Ice Arrow'.blvl) × par8 with Param8 = 12; it reads blvl, hard points only. Cold Arrow feeds Ice Arrow (+8% cold damage per hard point) and Freezing Arrow (+12% cold damage per hard point), which is where most of its points end up on a cold bow.
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 Basin's page says nothing more about this skill against players.
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
