How many times can you train a dragon? In my experience it was 4 times max, can you train more time just for changing elements? Cause I was thinking of like what @darthkerwin said in high commander special skill, both foam and wave combined, declining another element. Can you like train 4+ times to change elements frequently?

No you cannot, once a skill is trained it cannot be changed. FYI you could have asked this question in the same topic, there was no need for a second topic. Secondly, this is something you could have figured out in game just by trying it.

What I meant was when initially training the elements on the High Commander, don't replace Foam with Wave. Replace something else. But yes, you only have one chance to train each of the elements presented.

@darthkerwin high commander extra chances sucks in mine haha, i shouldve given 1 star ro high reign if only i knew its chances
