Csst

What and where is CSST and how do people 'abuse' it to level really fast?

 

csst is short for corrupted sand swept tomb which can be found in the forgery
(here)

people abuse it by throwing dugeon bombs so that dungeon entries are free and double xp bombs so they get twice the xp and repeatedly do the dungeon
beacuse of its design its very straightforward and easy to complete making it the ideal dungeon for spamming. morever, since there are often many people who join these parties the chances of dying are relatively low and even at the minimum level (71) it can be completed without much effort
this way, people rapidly gain massive amounts of experience to the point where some people believe it is abusing the system

 

Thank you!

 

For no effort, CSST is unbeatable in terms of XP rate (something like 250k raw per run, which works out to 1-1.5 million with a decent XP set and DXP bomb). For actual effort, Demon Cave and the various Dragonling sites in Sky Islands are apparently slightly faster with totems (although still pretty good without) since on average, one run of CSST = 80-120 kills in Dcave/Dragonling sites. It's also worth noting that you can run CSST with full cosmic, whereas trying to grind Dcave/Dragonlings in full cosmic without a large group isn't going to go very well...
