What you were expecting to happen, and what actually happened:
TLDR: The trait triggers at the end of my turn, too.
While testing traits resolving, for this bug: Zarg’s Boom Pile Trait Targeting Bug - Bug Reports - Gems of War | Forums, I tried a team of troops with “create/conjure a X storm when my turn begins” (Seriously, why do some say create and others say conjure?), and confirmed that the traits are resolved from top to bottom.
HOWEVER, I also saw that with bane of ambition in first place, and other troops below, it created a coloured storm at the beginning of my turn, but it creates a bonestorm at THE END of my turn. The enemy team always has a bonestorm active during their turn, with 8 turns remaining, and when my turn starts, it turns back to the coloured storm of my lowest troop.
So, I get coloured storms, but the enemy gets bonestorms. And I checked to ensure they had no traits that could create storms (they didn’t). So it seems bugged.
I tested again with 4 troops creating coloured storms and on the enemy turn it was also the same storm as on my turn, with 7 turns remaining. So, no new storm was created, unlike with bane of ambition.
I tested a team of only bane of ambition (2 copies, since I only have 2), and it always creates a bonestorm at the beginning and end of my turns. You can see the circle of the bottom of the screen drop off and reappear, showing a new storm has started, and the number is always 8 turns remaining.
How often does this happen? When did it begin happening?
Unclear.
Steps to make it happen again
Use bane of ambition. End turn.
