Can I use cleave to increase a B3 to a b4, then static burst to get a Y4, and then stack static burst and cleave to increase the Y4 to Y6?? This takes things further than the first question because rather than just using a heroic power in between the Cleaves I'm actually using a different skill.
If you have a B3 and your goal is to get a B4 and a Y6, you can do the following:
1. Use Static Burst to get a Y4 (and a P4) and then increase the Y4 to Y5.
2. Use Cleave to increase the B3 to B4 and the Y5 to Y6 (and increase up to 2 other dice by 1 each).
