1. First, check how many hours you have left before you make your stage
selection. Use this chart to find a starting number:
____________________
| Hours Left | Value |
| 17-16 | 1 |
| 15-14 | 3 |
| 13-12 | 5 |
| 11-10 | 7 |
| 9-8 | 9 |
| 7-6 | 11 |
| 5-4 | 13 |
| 3-2 | 15 |
| 1-0 | 17 |
2. Next, check your hunter rank. Use this chart to figure out how much to add:
_____________________
| Hunter Rank | Value |
| E-A | +0 |
| SA | +2 |
| GA | +4 |
| PA | +8 |
3. Add the number of the 8 Mavericks you have already defeated. For example,
if you have defeated Grizzly Slash and Duff McWhalen, add 2 to this value.
That will give you the level of the boss. All the level really does is decide
how much life they have.
If the boss is at least Level 4, you will be able to get a Life Up or Weapon
Up. If the boss is at least Level 8, you will be able to get a Life Up and
part or Weapon Up and part.
Now, what parts can you get? The following chart shows the location of each
part in the Parts chart:
___ ___ ___ ___
| 1 | 2 | 3 | 4 |
|___|___|___|___|
| 5 | 6 | 7 | 8 |
|___|___|___|___|
| 9 | 10| 11| 12|
|___|___|___|___|
| 13| 14| 15| 16|

attacks.
