OK guys - here's something new for you to check out.
I took my NPC for the second Promyvion quest. As we know the current formula is (on level 1):
NPC exp gained after completing quest = 300 + n x40
n = number of mobs killed
So basically - when you kill 20 mobs you should get:
Exp = 300 + 20x40 = 300 + 800 = 1100.
BUT!
Once I got into Promyvion I used my Chariot Band.
Quick reminder:
Chariot Band Experience point bonus: +75%
Maximum duration: 90 min.
Maximum bonus: 500
I killed exactly 20 mobs on level 1 and my NPC gained 1300 exp not 1100!
So it would mean that the formula changed into this:
Exp = 300 + n x 50 = 300 + 20 x 50 = 1300
And now I have 2 theories:
THEORY 1 The exp for each mob killed for your NPC raises when you repeat the quest. Meaning - when you do the quest for the first time you get 40 exp per kill, then 50, then... maybe more?
THEORY 2 The Chariot Band also works for your NPC - and if THIS theory is true it means that it gives 25% more experience for your NPC (you get 75% more) as:
exp per mob = 40
exp per mob + chariot band = 40 + 25% = 50
Please do more research - like take your NPC to Promyvion for the second time, kill 20 mobs on level 1 WITHOUT Chariot Band - and click on ??? - this should decide which theory is true. Or maybe there are more? Help me out! Thx.
PS: THanks a lot guys for keeping this thread alive and for filling it up with many many helpful infos!
