[Errata] The bottom of the card should read "attack abilities" instead of "attack actions". Only attack abilities can be performed from the summon's position. For the summon on the bottom, for any attack ability, you can choose to originate it on your hex, or the summon's hex, but not both. So something like "target all enemies within range 4" would target either all enemies within range 4 of you, or all enemies within range 4 of your summon. Keep in mind that you are still the source of the attack, so you would only suffer disadvantage on a ranged attack, or suffer the effects of a non-ranged retaliate, if the attacked enemy was adjacent to you. Also note this summon has no attack action or a base attack value. It cannot be commanded to attack with an "Attack +X" action, but it can be commanded to attack with an "Attack X" action (e.g. the Mindthief's "Possession").
