SetRenderStates and alpha

Hi all, is there a place where i can find out the combinations of let''s say: D3DBLEND_ONE D3DBLENDOP_ADD D3DBLEND_DESTCOLOR ...etc What combinations does people use to acheive the following: - for 50/50 blends - for bright transparent explosions - for a coloring effect, like when your character gets freezed in Diablo 2 - for simulating cloaking, the destination gets slightly distorted I know i can acheive the 1st three with SetRenderState, but i wanted to check what you guys use. Thanks, Gunner
