Mount

Max tiredness is 200, it starts getting tired at 195.

The max EXP varies from person to person, but the highest I have seen is 4608. Mine is at 4,600.

Also when I changed servers, the EXP reset, and I had a different max EXP each time. weird.

I've also noticed, that a mount initially, when I obtained it, gained 1 exp from 4 tiredness. Then at (I forgot which level), it became 1 exp per two tiredness, and then 1:1 ratio, and now that my mount is Lv 20, it gains 2 exp per tiredness. O.o
I wish I kept track of the exp.

BTW, I noticed that in the website, it says that the dragon mount lets you evade monster attacks. Does that mean that in zakum, if you get on your dragon mount, you can fly to the other side without taking the 8K damage?

Also, I noticed the 'swimming speed' thing, and my theory on it is that in Aqua, you swim (upwards) at a normal speed, but are still able to navigate on the floors with a 150% speed.
