Part 2:
On Kill: What you would've gained, had you been on time for the FATE.
Kill experience: 30,000
Killed x 2 experience: 30,000 + 30,000 (60,000) / Compared to: (37,500 (+25%))
Killed x 3 experience: 30,000 + 30,000 + 30,000 (90,000) / Compared to: (58,500 (+95%))
Killed x 4 experience: 30,000 + 30,000 + 30,000 + 30,000 (120,000) / Compared to: (76,500)
Killed x 5 experience: 30,000 + 30,000 + 30,000 + 30,000 + 30,000 (150,000) / Compared to: (94,500)
Example: You get 30,000 experience for completing X Fate, so if you skip out on the same FATE 1 time, you lose experience from what you normally should've gotten, had you been there at the right time. (30,000 + 30,000 = 60,000 experience, compared to 37,500 (+25%) for missing out on one.)
After 4 (just setting it there as a placeholder) despawns, it stops to increase.
