Ooh! Possible critical... Forgot second sudden strike...
Critical Confirmation - (1d20+2)[17]
Second Sudden Strike Damage - (2d6)[6]
Normal Damage - 1st (1d6+2)[7]; 2nd (1d6+2)[8]
Ok, I'm very sorry, but it turns out my stats for my Ghost Spike are actually wrong (apparently they're always masterwork), so I've posted up this correct table to help display my attack rolls.
{table=head]Roll|1st Attack|2nd Attack
To Hit|14|Natural 20
Critical Confirmation|-|18
Normal Damage|8|9
Sudden Strike Damage|7|6
Critical Multiplier|-|x3
Total Damage|15|Normal: 15/Critical: 33[/table]
Phew, sorry about that, I'll be more careful next time.
