Giants who have quake.... Right now with the current rules. When they quake they only hit opposing characters adjacent to their base correct? It is not within their reach. Or is it the other way? This keeps changing on me.

Thanks for the assist.

You'll Quake all opposing characters within two squares and line of fire from the giant. Worldbreaker is pretty cool like that.

First, always quote:

Quake: Give this character a close combat action; this character's damage value becomes 2 and is locked. Make a close combat attack that targets all opposing characters this character can attack with a close combat attack. Each character that takes damage from this attack is knocked back.

Giant Reach. This character ignores opposing characters' Plasticity and adds 1 to its d6 roll when breaking away. When this character is given a move action it can use the Carry ability. When this character is given an action that includes a close combat attack, all squares within a range of 2 and line of fire are considered adjacent. This ability can't be countered.

So as long as they are within 2 and Line of Fire they will be part of quake.
