The teenager ran over for his first RaboDirect PRO12 tries against Zebre last month, having been a fixture for Wales Under-20s at the Junior World Championships in the summer.
And the youngster got his just rewards with a senior international call-up this week - throwing him into the mix to face Argentina at the Millennium Stadium on Saturday.
He joins Dragons teammate Tom Prydie, as well as Scarlets props Samson Lee and Rhodri Jones, as the latest line of Welsh RaboDirect PRO12 talent to link up with their country for the autumn internationals.
Success has arguably been written in the stars for Amos ever since making his RaboDirect PRO12 debut at just 17 - and Edwards believes his natural talent will flourish at international level.
"Hallam Amos has an X factor," said Edwards. "He has got an ability to break a line, good footwork and a fair turn of speed.
"(Assistant coach) Rob Howley has watched him more times than me and speaks very highly of him.
"We've got to put time and effort into them and try to help them understand systems. We won't try to put too much on them.
"These guys have their own skills that they will bring to the table."
