Determining NPC Stats
Placeholder page.
How to figure out NPC stats, talents, etc. from .lua file info.
Life
All NPCs should have the 'fixed_rating' flag set to false (fixed_rating = false), meaning they have variable hitpoints when created. There may be some odd NPCs that don't have this setting.
We also need to know the variables for the NPC: 'rank', 'life_rating', 'max_life', and 'level_range'. Finally we also want to know the 'level_range' from the Zone. NPC.lua file 'level_range' is {x, y}. Zone.lua "level_range" is from {a, b}. NPC level range is almost always 'nil' for the max ('y' value).
Then we can figure out the NPC's possible life range (not counting talents):
- NPC's possible level range is {x, b}.
- Starting life is defined by 'max_life' (yes, backwards, I know).
- Life per level is defined by: Life_rating * (1+level/40)+(rank_lookup)
Rank_lookup is confusing but here's a table for you:
| Rank | Lookup Value |
|---|---|
| 1 | -0.2 |
| 2 | -0.1 |
| 3 | 0.1 |
| 3.2 | 0.15 |
| 3.5 | 1.0 |
| 4 | 2 |
| 5 | 3 |
| 10 (or more) | 6 |
Putting It Together
Using Subject Z as our example:
- NPC level_range: {10, nil}
- Zone level_range: {10, 25}
- Subject Z's level is therefore {10, 25}
- Subject Z's rank is 4, rank_lookup is 2
- Subject Z's max_life is 100
- Subject Z's life_rating is 12
Per level-up HP gain is: 12 * (1+current_level/40)+2 or 3+(current_level/40)
Starting life is 100.
To get a fully accurate count we'd have to compute for level 1, level 2, level ... level 10 and add all the values. We can average and multiply for a faster but less accurate result. Instead of summing, we use 12 * number_of_levels * (1.2+average_value/40).
Lowest possible level: 10. Number of levels-ups: 9. Average value: sum(1->10)/10 = ((10*11)/2)/10 = 5.5.
FINALLY (you've stuck with this math? good on you):
- Total HP (for Level 10): 100 + (12 * 9 * (3+(5.5/40))) = 438.
- Total HP (for Level 25): 100 + (12 * 24 * (3+(32.5/40))) = 1198
