The Lancers are melee fighter but they outrange most of their
opponents with their two-handed polearms. Their attacks consist of a
barrage of thrusting with their long reach weapon of choice. They can
stay safe while dealing lots of damage to the enemy.
Lancers need a polearm for their attack. This is a close- to-mid
range combat weapon that features a blade at one end of a long shaft.
Polearms can be Halberd, Lance or Spear.

FFXIV Lancers Skills Abilities
The Lancers have several Attacks with the use of their polearms. Final fantasy 14 guide gives us the rundown of the Lancer Attacks he can use to deal damage. These are:
Thrust – This is the basic Lancer Attack that uses the polearm and deals piercing damage.
Skewer – Lancer runs through all the enemies until he reaches the target. It increases attack power and deals piercing damage to all the enemies between the starting point and the target. Non-flying targets are slowed by this attack.
Trammel – This attack cripples the target, which renders it immobile for a period of time.
Moonrise – Lancer deals slashing damage and reduces
the target’s TP generation. This attack will upset the enemy because it
has to change its tactics.
Doomspike – Lancer stabs with force that deals piercing damage to the target and every enemy in between.
Leg Sweep – Lancer strikes low to deal blunt damage and stuns enemies in front of you. This Attack will not affect flying targets.
Feint – When used, Lancer stabs with accuracy and
timing to ensure a successful attack and deal piercing damage. This
Attack can only be used after the target evades an attack.
Final Fantasy 14 guide states that Lancers have abilities to make his
Attacks more powerful and efficient. He can opt for any of the
following Abilities when fighting an enemy. These are:
Ferocity – This triggers an adrenaline rush, which increases the Lancer’s power during the next attack.

ability to absorb HP.
Invigorate – Lancer channels his physical energies to gain TP.
Comrade in Arms – This boosts the morale of party
members. Target will have a debilitating status that grants party
members faster TP generation.
Collusion – Lancer uses deception to transfer enmity
generated by next successful attack to a party member that is
positioned between him and the target.
Life Surge – Lancer gains enhancing buff that grants
him the ability to absorb HP. When active, successful attacks reduce
the target’s evasion.
