Wow, I have so many characters I don't know where to begin. Yes, I do... the one that needs a something specific that isn't already available. Cloudbreak, an Electric Melee/Dark Armor Brute themed like a storm melee. I took Ice Mastery to get the Ice Storm effect so I could have some sort of rain, but she needs a proper Storm Mastery PPP.
1. Downpour (similar to Storm Blast -> Cloudburst but adds a -SPD effect to the target)
2. Lightning Strike (similar to Storm Blast -> Direct Strike but not a snipe, reduced damage, and adds a Hold effect)
3. Storm Cloud (similar to Storm Blast -> Storm Cell but follows caster and grants +Recovery in addition to small chance of triggering lightning strikes low damage whenever you use other powers in this pool)
4. Thunder Clap (Storm Summoning, pretty much as is)
5. Heavy Rain (Storm Summoning -> Freezing Rain but without KD and adds -ToHit to affected targets)
