The Gunpowder Bombardier, a ninja archetype from Heroes From the Fringe, don't specifies the type of action required to use Gunpowder Bomb. Is it a swift action, a standard action, or an attack that can be done anytime a ranged attack is possible (e.g. full-attack action)?
The ninja basic ki uses are swift action (e.g. extra attack on a full-attack), which make the swift action answer plausible. However, the standard action and the third interpretation can also be defended. What do you think?
