In PoE2, you generally gain Frenzy Charges by using specific skills or effects that explicitly generate them, not just by hitting enemies normally. The most commonly cited ways are Combat Frenzy , Cull the Weak , Sniper’s Mark on crit, and Retort , with some build-specific options like Parry/Disengage combos or unique-item synergies.

Common ways to get them

  • Combat Frenzy : grants a Frenzy Charge when you Freeze, Electrocute, or Pin an enemy, with an internal cooldown.
  • Cull the Weak : if it hits at least one enemy, it grants a Frenzy Charge.
  • Sniper’s Mark : on a critical strike against a marked enemy, you gain a Frenzy Charge.
  • Retort : supported skills can generate a Frenzy Charge by consuming an enemy’s Parried Debuff on hit.
  • Parry + Disengage : an early-game method that can be used to trigger charge gain.

What matters in practice

For many builds, the easiest setup is to pair Combat Frenzy with a reliable way to apply Freeze, Electrocute, or Pin. For bossing, Sniper’s Mark can be more consistent if your build can crit reliably. If you’re using a weapon or skill setup that already leans into Parry, Retort is another solid option.

Simple example

A practical Ranger setup might use Combat Frenzy for general mapping, then Sniper’s Mark for tougher targets where you can keep critting. That gives you charge generation from two different angles instead of depending on just one mechanic.

Current takeaway

So the short answer is: you gain Frenzy Charges in PoE2 through specific charge-generating skills, marks, or conditional support gems , especially Combat Frenzy, Cull the Weak, Sniper’s Mark, and Retort. If you want, I can turn this into a build-by-build list for Ranger, Monk, or melee.
