The following table shows the time limit to complete each XP chain based on the monster's level and chain #.

C = Chain # (1-5)
L = Enemy Level
Chain Time Limit = (L+10) * (6-C) [seconds]

For example:
If the mob is level 40, and you are going for chain #3.

Then the time limit for chain #3 will be:
(40+10)*(6-3) = 150 seconds

NOTE: It has nothing to do with player level, it's totally dependent on the monster's level.
