his charges refresh by minutes of rest. he may only have, say, 10 charges at level 10, but after the fight he can sit on his butt for a few minutes and get them all back.
he already gets the Special Beam Cannon and Kienzan at level 20, and Renzoku at level 8, Plus he gets flight and Instant transmission (Dimension Door rangw only).
If you want a super mode, play a Half-orc Dire Wereape barbarian, gestalted with this class, and refluff the orc's appearance and the barbarian's rage. there, now you have a saiyan with Oozaru and Super Saiyan transformations.
also, I need to edit the last Advanced Ki Blast. the death effect means everyone will go for Kienzan all the time, so that has to go. They're now just really strong blasts that have great crits.

Edit: added the table. as for other Advanced Ki Blasts, you could always make an ACF for different signature attacks at 20, or switch out Instant Transmission for an extra advanced blast, or something. but I can't fit every single technique ever used into a single twenty level class and have it make any sense. That's why i stuck with the basics, besides IT. goku, vegeta, krillin, cell, and frieza all used the Kienzan. It's generic like that. Tao, Piccolo Daimao, Piccolo Jr, Tien, Chiaotzu, Frieza, and Cell all had piercing rays. It's generic. Kamehameha, Galic Gun, and Masenko are all basic beams. Goku, vegeta, gohan, and frieza all spammed a Renzoku from time to time.
as for infusing Ki into melee attacks, that's why i left Ki strike in from the original monk. first your attacks are considered magic, then they are aligned, and then adamantine. I might even change the last one to be able to alternate with cold iron or silver, as well, for a bit more variety.
then the monk becomes an all around defense bypassing machine. his ranged attacks knock around incorporeal creatures, and always do at least 1/2 damage if they hit, no matter how suck you roll for damage. his melee attacks can alternate alignments and materials as needed to bypass DR. as long as he's not actually inside an AMF, standard magic defenses don't do anything to him. If he has trouble getting past AC, he can eventually use beam to force a reflex save, instead.
