Whether you're in mid to end game, this build will keep you at the top of your game.

Getting Started: Key Skills for Your Lightning Monk
1. Primary Skills Overview
To make the most out of your Lightning Monk, focus on the following skills:

Killing Palm: This melee skill is crucial for healing and managing energy charges. Use it to finish off low-health enemies marked with a blue orb to recover 12% of your health and gain energy charges.

Falling Thunder: An AOE lightning attack that consumes energy charges for increased damage, wider area, and extra range. Ensure you activate this skill when you have energy charges stacked.

Siphoning Strike: This skill generates energy charges when you hit shocked enemies, making it essential for maintaining your damage output, especially against bosses.

Storm Wave: Launches a stream of lightning that deals damage and can apply shock to enemies from a distance, allowing you to attack without getting too close to enemies' melee abilities.

Tempest Spell & Tempest Flurry: Tempest Spell drops a resonating bell that damages enemies and provides stun potential. Tempest Flurry then delivers rapid melee strikes to trigger the bell for more AOE damage quickly.

Charge Staff: Unlock this skill towards the end of Act Two. It allows you to consume energy charges for enhanced lightning-infused attacks, great for clearing out mobs efficiently.

Herald of Thunder: This spirit skill releases lightning bolts in the vicinity, dealing damage to enemies every time you kill a shocked enemy, significantly boosting your AOE potential.

2. Gem Setup and Combinations
To amplify your skills effectively, use the following gem setups:

Killing Palm: Pair with Life Drain (12% health recovery per kill) and Profusion (50% chance for multiple energy charges per kill).

Falling Thunder: Add Perpetual Charge (35% chance not to consume energy charges when casting) and Nate (35% additional lightning damage against shocked enemies).

Tempest Spell: Utilize Ruthless (500% more stun build-up with every fifth use) and Magnified Effect (40% more AOE damage).

Herald of Thunder: Equip Precision (increases accuracy) and Concentrated Effect (40% more damage, reducing AOE by 50%).

Tempest Flurry: Use Conduction (100% chance to shock) and Overpower (50% more stun build-up) alongside Martial Tempo (25% increased attack speed).

Passive Skill Tree Progression
Maximizing your Lightning Monk's efficiency involves strategic passive skill tree choices:

Flow Like Water & Step Like Mist: These nodes boost attack speed, mana regeneration, and movement speed—ideal early game pick-ups.

Taste for Blood: Grants additional life per enemy killed, along with a chance to replenish health instantly.

Essence of the Storm: Focus here to enhance your lightning damage and shock chance.

Power Within: Increases crit damage and the number of power charges you can hold.

Conservative Casting: Boosts mana regeneration, essential for spamming your skills during intense boss fights.

Boss Strategy: Overcoming Jamra the Abomination
You’ll encounter various bosses, with Jamra the Abomination being notably resistant to lightning damage. However, by playing aggressively and managing your energy charges while utilizing your skills effectively, you can pressure the boss and minimize their ability to perform dangerous attacks. The key is to stack energy charges through Killing Palm and Siphoning Strike, maintaining high DPS with Falling Thunder and Tempest Spell.

Approach Aggressively: Keep up the pressure on Jamra to avoid letting him unleash his deadliest attacks.
Use AOE Skills Strategically: Utilize Tempest Spell and Falling Thunder to buy POE 2 Currency maximize damage in phases where he summons minions or exposes himself.
