Does it suffer an extra -1 for firing multiple shots? If so combined with long range and moving you (almost) never get to take advantage of poison since you would most likely charge if you were within 8 inches unless I'm missing something?
Interesting question as it does not have the choice to fire one shot each...... mmmmm ...... I'd like to see the answer to this one too!
Hmm... Well the BRB says that a weapon with the Multiple Shots rule can either fire once OR as many times as indicated by the rule, so long as it applies the -1 penalty. So yah, I'd say RAW the Giant Blowpipes suffer -1 to hit when firing 2D6 shots. Anyone see that differently?
Nope, it's like you stated. In the last book the giant blowpapes didn't have the "multiple shots" rule but fired "2D6 shots", therefore there was no penalty. Now there is.
