I've added the rogue level for an extra 1d6 sneak attack and skill points. This type of assassin is deadly if it attacks an unaware party (e.g., no PC with
See Invisibility, Blindsight, or
Invisibility Purge ready...) and can attack within a favorable terrain, e.g. a city.
If you want to add more class levels, try either assassin (more spells, sneak damage), tempest (better AC and melee combat power), street fighter (better defenses, sneak +1d6) or perhaps try the scout/dervish way instead of rogue/assassin (but this would result in a lower sneak damage).
Hope that helps.
EDIT: Roughly checked the skill ranks and removed some errors. Maybe the skill point total is not yet correct...
