The 20-year-old has notched up five tries in the GUINNESS PRO12 this season in what is his is fourth league campaign with the Dragons.
The Welshman has also been instrumental in his team's build-up play too, including beating three men with his hand-off to Carl Meyer who crossed during their 26-22 win over Ulster Rugby.
His teammates now enjoy a two-week break before the GUINNESS PRO12 returns at the end of the month but Amos will be hard at work with the Welsh squad.
And while his powerful displays have been catching the eye, he insists it's experience and not gym work that has helped him step up this season.
"I wouldn't have said that I have changed particularly physically over the last few years but this year I am more confident and that's massive," he told the South Wales Argus.
"I have hit 50 games for the Dragons and the more opportunities you get (to run) the more you take people on and beat them. That makes you even more confident and it's easier in the future.
"I've never really been afraid to take people on; I am more of an optimist. Psychologists talk about positive imagery and I do that naturally.
"I don't really consider the mistakes. The repercussions come if you make them but you've just got to deal with it and move on."
