One of the problem is that they they murder people who doesn't load into the map quick enough when they switch map, change channel, or log in, by making squishy class extremely vulnerable to other monster in the map upon getting potion lock.
There should be a 10 second immunity (or make it so the afk mob cannot aggro onto someone that has not been in the map for at least 10 seconds) from the afk mob upon switching map, changing channel, or when logging in.
Or change it so the anti-afk mob auto-die after 1 minute, so if the map is unoccupied for more than 1 minute and someone enter it, the anti-afk mob would instantly die for being alive for more than 60 seconds.
Or change it so the anti-afk mob doesn't deal damage and potion lock, but cast a short range stackable uncurable debuff (4 second cooldown, last 10 seconds, duration refreshes if stacked) that instantly kill you if it reaches 5 stack
"All Skills: +1 (except 5th job skills, which can only go up to the skills's master level)"
The phase was meant to be read in a horizontal list containing 2 items (a horizontal list is a list of things in a single sentence separated by a comma).
If it was a numbered vertical list, it would look like this
All Skills: +1
1. "Except 5th job skills"
2. "Which can go up to the skill's master level"
In this format, you can see the All Skills: +1 does not affect 5th job skills, and it only goes up to the master level on skill it has an effect on.
Though in my opinion, the word "which", really make it sound like item #2 is talking about item #1 when they should be two separate items that does not relate to each other at all, which lead to this misunderstanding.
If Reboot really was free2play as it claims to be, then pets should be obtainable with mesos as well since they're essential in looting massive amounts of mesos. But guess what, they're not.
Hard Hilla drops a box most of the time that give free pet half of the time.
