As of now I merged wind and lightning mastery to form Weather Mastery. The extra slot is used by Flash Freeze, which freezes her opponent and slows surrounding enemies. (kind of like ice man's cold crush with a prettier charge and different sounds.
The tribal skin didn't work because of Wanda's Boots. Oh well.... The booster is finished and is found here:
Storm_Booster.zip:
Admin note: Link has disappeared
This changes Lightning and Wind Mastery to Weather Mastery and Flash Freeze. (with new icons for both moves)
Like Jean's booster I am giving you the option of choosing 9 skins from 10.
01 - Astonishing [PS2 MUA version]
02 - AOA
03 - Ultimate (Crazy hair)
04 - Ultimate (Ponytail)
05 - Retro (Mohawk) [PS2 MUA version]
06 - Classic (Jim Lee) [PS2 MUA version]
07 - Ultimate (Long Hair) [PS2 MUA version]
21 - Original
22 - Civillian (Hood)
23 - Xtreme
The herostat I supply doesn't include 07, but if you want it just replace any one with it.
I made a new 3d hud from Jean's to go with 06 and 07. Unfortunately I have no way of making a new 3d hud for 05 cause the mohawk doesn't appear in XML2

. I also made conversation huds to go with 01, 02, 04, 05, 06, 07 (same as 04), 21, and 23. Additionally I hexed the skins for 05, 06, and 07 to reflect their numbers. (I didn't have to do it with 01 because the MUA and XML2 number for that skin are the same.)
Again I am not responsible for anything that goes wrong, but I tested it and it works great.
