Passive. Your attacks have a chance to do double damage.
Critical Strike is a level 1 Amazon passive (Passive and Magic tree, no prerequisite; it unlocks Penetrate). Every physical attack rolls against its chance and, on a success, the physical damage is doubled. The numbers that decide it are the chance, 68% at level 20, and its ceiling of 80%, which the diminishing curve approaches but never reaches at any level a character sees.

dm12, the diminishing-returns calc between Param1 (the minimum, 5) and Param2 (the maximum, 80). The Basin's page writes the curve out: min(5 + [75 × [(110 × slvl) ÷ (slvl + 6)] ÷ 100], 80), and the table's values follow it: 16% at level 1, 42% at 5, 56% at 10, 63% at 15, 68% at 20, 71% at 25, 73% at 30.The calc reads lvl, so +skills from items raise the chance; the passive is applied through passivestat1, passive_critical_strike.
Critical Strike is a passive state (criticalstrike) with no cast, no duration and no radius. It is rolled on each attack that lands, and by the Basin's page it doubles physical attack damage when it succeeds, even barehanded. That is the damage described on Dealing Physical Damage and Weapon Damage, after Enhanced Damage has been applied; elemental damage on the weapon is not doubled.
Because the Amazon's conversion arrows convert after the doubling, the Basin's page lists the converted damage of Magic Arrow, Fire Arrow and Cold Arrow as doubled too (and, for other classes, Lightning Bolt, Fists of Fire and Berserk). The same page lists the attacks it never applies to: Impale, Dragon Talon, Dragon Tail, Dragon Flight, Sacrifice and Smite.
Critical Strike and Deadly Strike are exclusive: if one succeeds the other is not rolled, so the hit is doubled at most once. By the Basin's page the combined chance is 100 − (100 − CS) × (100 − DS) ÷ 100.
The Basin's page adds that non-player units such as a Valkyrie or a mercenary have their own 5% critical chance that doubles all damage types and is rolled independently of this one.
No synergies: the row has no SymPerCalc column, the skilldesc row has no dsc3 line, and no skill reads Critical Strike's points. The chance reads lvl, so +skills count in full; the Basin's page notes it is also granted as an oskill by the Insight rune word.
A player's hit on another player is cut to 17% of its value (difficultylevels.txt PlayerDamagePercentVSPlayer) before anything else, see Player versus Player; a doubled hit is doubled first and cut second. 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
