Cloak of Shadows and Necromancer Curses

[moget?]

Hi,

If I am not mistaken, the following skills are on the "curse" tier of spells, and overwrite eachother:

All necro curses, Cloak of Shadows, and Battlecry (and shrines).

Also, the curse Attract cannot be overwritten by any curse.

These other skills can be used on the side (without overwriting): Taunt and Inner Sight/Slow Missiles.

The only spell I am usure of is Conversion/Mind blast.
