Can the Arborec's "Mitosis" ability be used to place 1 infantry on every planet they control?
No. Only 1 infantry may be placed on a single planet using this ability.
Can the secondary ability of the “Warfare” strategy card (pre-Thunder’s Edge) be used to trigger the “Production” ability of the Arborec’s Letani Warriors?
Prior to the Thunder’s Edge updated “Warfare” card: No, the “Warfare” secondary ability can only be used to trigger the production ability of space docks, and thus cannot be used by the Arborec to produce additional infantry. Addendum: The change to the “Warfare” strategy card made in the Expansion Thunder's Edge now allows this.
Can the “Production” abilities of multiple Arborec “Letani Warriors” in a system be combined to allow the production of two infantry for one resource?
Yes. Production value is totaled when the “Production” ability of units in a system is used.
Does the Arborec flagship (The “Duha Menaimon”) need to be in a system when it is activated to make use of its ability?
Yes. The “Duha Menaimon” can only be used to produce units when it is in a system at the moment it is activated.
Can the technology "Sarween Tools" be used to reduce the cost of units produced by the Duha Menaimon?
No. Sarween tools can only be used when a unit specifically uses the PRODUCTION ability
When using the Arborec's hero ability "Ultrasonic Emitter", does the cost for the produced units need to be paid for?
Yes. Any game effect that instructs a player to produce units requires them to pay for them unless otherwise specified.
