I got one of the new Steggies (finally) and I see that there are builds for the great bow OR gaint blowpipe OR Engine of the Gods. So does an ancient stegadon with a skink priest and EOTG still get to fire the giant blowpipe?
No, it does not. It would be nice, but it is not included in our rulebook under the EOTG entry. In some ways, it would be a little too powerful if you could. You still have it with the skink chief and warspear though.
