The spellcaster I used it on quickly cast Faerie Fire to defeat it, so I only successfully used Ghost Step (Invisible) twice against him.
Only two full attacks with the bonus damage dice?
Let's compare equivalent level characters, and how much two full attacks with Sudden Strike will hurt. For simplicity's sake, the Ninja's STR mod and the Wizard's CON mod are the same.
3rd Level
Mage: 3d4 + 3 x CON .............. Average HP: 9 + 3 x CON
Druid/Cleric: 3d8 + 3x CON ............ Average HP: 17 + 3 x CON
Damage from 2 SS: 2 x [1d6 (Base) + 2d6 (Sudden Strike) + STR] ...... Average Damage: 21 + 2 x STR
8th Level
Mage: 8d4 + 8 x CON .......... Average HP: 21.5 + 8 x CON
Druid/Cleric: 8d8 + 8 x CON ........... Average HP: 39.5 + 8 x CON
2 SS: 4 x [1d6 (Base) + 4d6 (Sudden Strike) + STR] ......... Average Damage: 70 + 4 x STR
Point being, once that iterative attack comes into play, a full attack with Sudden Strike becomes something even a d8 Hit Die character can hardly stand. It's absurd.
The Ghost Step ability lets the ninja get in the one hit that will ensure that 99% of victims will die; no NPC classed character will survive that. Nor should they... it is a ninja after all. The ability lets the ninja get in and out of places quietly and kill people without warning. OK. But he'd better bloody well kill him in the first attack, or he's out of a job.
Or it lets him disappear for one round, and that ain't shabby at all. No sir. The ability can be offensive in use, or defensive. He can't very well be attacked (barring a ubiquitious
See Invisibile) if he's invisibile, can he?
RAW, it grants invisibility for one round. But I cannot but believe that this was an oversight. I'm waiting for the eratta, and until then am willing to reside in the House Rules forum over this.
