Commander Effects
Emperor Palpatine on Throne
Q: Can a character without a Force rating spend this character's Force points?
A: Yes.
Jabba the Hutt
Q: Does Jabba's commander effect refer to characters with the Bounty Hunter ability, or Bounty Hunter in their name, or both?
A: The Bounty Hunter ability only.
Mercenary Commander
Q: When a character with Mercenary gains Furious Assault, can he use it if he starts in a square where he can make an attack?
A: No. The character would only be able to use Furious Assault when the Mercenary restriction is not applicable.
Moff Jerjerrod
Q: Would this effect stack with Baron Fel's commander effect, or Battle Meditation, or Control Minds?
A: Yes to Baron Fel's effect; it modifies the combined fire rule rather than directly affecting a statistic. Yes to Battle Meditation; it specifically says it stacks with such abilities. No to Control Minds; it creates another direct bonus to a statistic from a commander effect.
Xizor
Q: Does Xizor's commander effect refer to characters with the Black Sun ability, Black Sun in their name, or both?
A: The Black Sun ability only.
