Aklex Prime is the Primed version of Aklex, and consists of a pair of hard hitting semi-automatic pistols. Functionally very similar to its single handed counterpart, the Lex Prime, the Aklex Prime trades some accuracy and reload speed for improved rate of fire and magazine capacity.
The Aklex Prime components can be acquired from Axi A2 Relics purchased from Baro Ki'Teer in the Concourse section of the TennoRelay for 45,000 45,000 and 5050 each. Note that Baro Ki'Teer's stock changes with each appearance, and this relic may not be available on a succeeding appearance.
Compared to Lex Prime: the Aklex Prime has higher Sustained DPS (332.6 vs 245.5) and higher burst DPS (504 vs 393.8).
Aklex Prime has more recoil and less accuracy than Lex Prime, making consistent headshots difficult. Using Steady Hands mod may make up for this, but will reduce overall DPS in favor of standard Lex Prime.
Aklex Prime has a higher Riven disposition than Lex Prime (Neutral vs Faint). It may be beneficial to use a riven with reduced recoil stat to increase viability of Aklex Prime without taking a huge decrease to DPS (provided the Riven has other DPS enhancing stats).
Aklex Prime can make use of Mesa's passive ability, giving it +10% fire rate, resulting in an increase of 16.7 Sustained DPS (349.3 increased from 332.6) and 39.4 Burst DPS (543.4 increased from 504).
