FAMILIARITY PER SPECIES?
Killing a species builds familiarity with it, from level 0 to 50. Familiarity raises the XP and loot you get from that species.
Level 0 = 1.0x XP and loot
Level 50 = 2.0x XP and loot (linear in between)
PROGRESSION
Each level needs more kills than the last:

| 1 → 2 | 10 |
| 2 → 3 | 20 |
| 3 → 4 | 30 |
| … +10 kills per level … | |
| 49 → 50 | 490 |
Reaching level 50 takes 12,251 cumulative kills of that species. Familiarity caps at level 50.
