As the title suggests, if you see anyone running around at 100mph, its most likely a Zerker, they have OP movement buffs that give crazy speed. If not, its possible to stack speed buffs
*Purple Tree Sap(forgot what its called) +10% Movement Speed for 15 mins.
*Boots Alchemy +10 +15% Movement Speed
*CS Items +10% Movement Speed


*Zerker Buffs +75% Movement Speed, 50% for 10secs, 25% for 45secs.

*Light Speed Potion +10% Movement Speed for 10secs.

*Fastest Mount +50% Movement Speed while in use.


Total +170% Movement Speed


Considering base speed is 450, this would up it to about 1215 Movement Speed, which is insane.
Without the mount its 990.


I just wanted to clear that up.
