Simple Q&A (By RAW) III

[Jasdoif]

Sorry Fax, but the first line of the ability's description is "As a standard action". (CWar pg 69)

The answer is the same.

Like any ability that requires a standard action instead of simply affecting an attack, you cannot combine it with Manyshot (which requires a separate standard action) or a full attack (which is a full-round action).
