The the 4-match part. After convert the gem, you got 3 separate gem 4-match on board. Does it count as 3 match or just 1 match?
The skull match part. If there are 3 separate normal skull 4-match. How the damage calculated? Does it deal 3\*base damage or just 1 base damage?
Can anyone help on this? Thanks!

First part: it counts as three 4 matches and gives you 4x3=12 mana. However it only triggers the trait once
Second part: a 4 skull match does base attack+1 damage. So three 4 skull matches do (base att +1) x3 damage
