When using Jax, Grandmaster at Arms' ability to attach gear to Irelia, Fervent, does she get +1 from being chosen by Jax's ability, and does she get an additional +1 from the gear being equipped to her?

Ruling: When using Jax's ability to attach gear to Irelia, she only gets +1 from being chosen by Jax's ability, not an additional +1 from the gear equipping. When detaching gear from Irelia using Jax's ability, she does not get +1 because you are targeting the gear and the destination unit, not Irelia herself.

Sequence:

• When using Jax's paid ability (1 energy + tap) to attach gear to Irelia: You target Irelia and the gear, Irelia gets +1 from being chosen
• When using Jax's tap ability to detach gear from Irelia to another unit: You target the gear and the destination unit, Irelia gets no +1
• When equipping gear to Irelia normally (using the gear's Equip ability): Irelia gets +1 from being chosen by the Equip ability

Nuances:

• Irelia's trigger only cares about being chosen/targeted by abilities you control, not about the gear itself choosing her
• Jax's abilities target specific things: the paid ability targets a unit and gear, the tap ability targets gear and a destination unit
• The Equip keyword is an activated ability that targets a unit, which would trigger Irelia's +1 separately from Jax's ability
