Guard

A Hit is an instantaneous damage event. Any damage that is not damage over time is Hit damage, whether it comes from an Attack, a Spell, Thorns, or another effect.

A Buff is a beneficial effect applied to a player, Minion, monster, or other target for a duration or while a condition remains true. Buff Magnitude comes from the creator, while Buff Effect usually comes from the affected target.

Duration is the length of time a skill component, Buff, Debuff, Ailment, Curse, Mark, Minion, Totem, Flask effect, Charm effect, Hazard, or delayed event remains active. Each duration modifier applies only to the effect type it names.

Energy Shield is a rechargeable defensive resource that normally protects Life. Damage is mitigated first, then removes Energy Shield before Life unless the damage or another effect explicitly bypasses it.

Runic Ward protects the final point of Life. When damage would reduce Life to 0, Life stops at 1 and current Runic Ward absorbs the remainder. The character still dies if the remaining damage is greater than the Ward available.

Consume all stacks of Jade to grant Guard based off your maximum Life for each Jade consumed. You cannot gain Jade stacks while you have Guard.

Perform a Warcry that grants Guard and Triggers Shield Wave when subsequent Shield Attacks deal damage. This Skill's cooldown can be bypassed by expending an Endurance Charge.

Sacrifice your Runic Ward to send out an energy pulse that grants nearby Allies Guard.

Combo is a counter owned by a specific skill. Strike enemies with the weapon set bound to that Combo skill, then spend the required count to use the skill or improve its result.
