Sorry, k3nj1n, just now saw your message. If I'm understanding your list correctly, you want the following:
1) Attack 1 - +14 attack bonus, Damage of 4
2) Attack 2 - +9 attack bonus, Damage of 9
3) Attack 3 - +4 attack bonus, Damage of 14
That's a lot of variation of attacks. Frankly, with how he system is put together, you can't build this as a vanilla character unless attack 2 is a different range than 1 and 3 because you can modify the attack bonus of a power by 1 with Attack Focus, which applies to all ranged or all melee options, or by 2 with Attack Specialization/Accurate, which apply to a single attack. Let's say that 1 and 3 are ranged and 2 is melee for the sake of argument.
First, you need the lowest attack bonus. Let's make his base attack to be +4 (8 pp). Now, we buy 5 ranks of Attack Focus (Ranged). Lastly, buy 5 ranks of Attack Specialization. Create Attack 1 as Strike 14. Create Attack 2 as Blast 9. Create Attack 3 as Strike 4 and set Attack Specialization to Attack 3 (alternately, you could give Attack 3 five ranks of Accurate).
Looking at it again, it would also be possible to make all of the attacks ranged, or all melee, by messing with Mighty and particular values of Strength to increase the damage of certain attacks.
^_^ Does that answer the question?
