Dragon attack.

Interesting scheme, thank you to the author for creating it! I didn't understand some points before, but now I'll know some small nuances.
I don't know, I immediately understood everything in the table; everything is clearly explained.
The dragon doesn't always burn in a straight line, as indicated by the sword (cursor). This happens when attacking two-cell units. When attacking, the dragon lands with its front part on the spot where the cursor points. If the dragon needs to turn around to attack, it lands with its tail on the spot where the cursor points. With two-cell units, it's slightly different. In the second case, the dragon doesn't turn around but chooses to attack the back part of the two-cell unit, and the burn goes shifted by one diagonal. However, if we were to the right of the target before the attack, during the movement, the animation turns the dragon around, and it lands with its head to the left, and attacks a different diagonal.

To put it simply, when attacking a two-cell unit, if we're flying from the left, the dragon attacks the tail, and if we're flying from the right, the dragon attacks the head.
