~Kurama's Attacks~

Rose Whip - Using his spiritual energy he can turn a rose into a whip with thorns that can slice through just about anything

Fuuka Enbu Jin - He can create a torrent of razor sharp rose petals to rain down around him (I think its the attack he started off using in his fight against Karasu).

~Hiei's Attacks~

Jaou Ensatsu Koku Ryu Ha - most powerful of his attacks. When he uses it a really big black dragon comes out and destroys everything in its path.

Jaou Ensatsu Ken - Hiei summons black fire in the form of a sword around his right fist. (Looks some thing like Kuwabara's Rei Ken, but its black/ greenish blueish @.@)
