i just started playing and i dont know what to do i just go play at the arcades and get crystals.
is there anything else to do?
what should i do at the beginning? (im a noob)
If you do buy the Brandish, I would recommend taking the "Iceburst Brandish" upgrade path. It gets really useful later on, in tier 3.
The auction house is really quite handy. You can buy gear there for quite a bit cheaper than from vendors. If you're in new looking gear, you might get people trying to sell you equipment while you're standing around, usually they're trying to give you a bad deal. (Someone tried to sell me a 1 star sword for 2000 crowns. Ick.)
Look around on the auction house, try to get into two star gear, it's not very expensive, after a run through the clockworks, you should be able to afford something. If you're the planning sort, read the wiki and deceid what sort of gear you want. If you're not the planning sort, buy whatever's cheapest or looks the coolest on other players. The big thing here is to have fun.
And, if you're looking to spend real money on crystal energy (That's what goes into the bunch of zeros in the lower right corner, above your mist energy bar), now is a great time to sell it, there's an automated market thing. You can sometimes get 7.000 crowns per hundred mist energy. It's very easy to dress in awesome gear like that.
Once you have reached the haven, the best thing to do is go to the arcade (head north) and do a tier 1 run (go to a gate and click on join party) from then on use all the mist energy you have on that run (if you dont die and spend energy reviving you should clear it using 90 energy (if you go all the way through it that is)) Once you have done that you should have some crowns, the best thing to do is go to the auction house which is located in the middle of the haven and search for a new weapon, i would recommend the brandish or the calibur, if you dont have enough crowns use a mist tank you get from clearing the tutorial and do another tier 1 run. Once you have that that should be it for that day, nothing much you can do im afraid, unless you spend real money on crystal energy. Keep doing tier 1 runs untill you can afford some armour (I recommend the wolver coat and cap) Then just use the wiki on this site to advance through better armour, weapons and advance to better tiers. Hope this helps.
