Cannon Shooter SP build.

I did early 2nd job far differently and it worked out pretty well I think:

30. 1 Slug Shot
31. 1 Critical Fire, 2 Mastery
32. 3 Mastery
33. 3 Booster
34. 3 Booster
35. 3 Rush Boom
36. 3 Rush Boom
37. 3 Rush Boom
38. 3 Rush Boom
39. 3 Rush Boom
40. 3 Rush Boom
41. 2 Rush Boom, 1 Monkey Magic
42. 3 Monkey Magic (Perfectly lines up it's duration with 6booster, nice little setup for a skill macro)
43. 3 Mastery
44. 3 Mastery
45. 3 Mastery
46. 3 Mastery
47. 3 Mastery
48. 3 Pirate Training
49. 3 Pirate Training
50. 3 Pirate Training

Totals:

• 1 Slug Shot
  
• 1 Critical Fire
  
• Max Mastery
  
• 6 Booster
  
• Max Rush Boom
  
• 4 Monkey Magic
  
• 9 Pirate Training
  

The stability that Slugshot gives is really, really useful and I don't know what I would have done without it at times. It's an excellent level 1 skill, whereas to really fully utilize Rush Boom, I had to dump points in it for quite a few levels. I'd say Slugshot and Critical Fire are the two best 1point-and-forget skills in the entire 2nd job book, they give a lot of usefulness out the door.
