I downloaded this via steam, and it's pretty fun so far. Any tips for a noob?
1. Read the wiki! Don't read about the bosses if you don't want spoilers.
2. Play with mist, craft with crystal.
3. Don't energy revive in a party, until everyone is down. Then decide on one guy to energy revive, who will then HP revive capable knights.
4. Pick-up group (PUG) is usually not the best idea. Make friends, join a guild!
5. You are always out-numbered by the enemies, so defense is many times more important than offense. To win means to stay alive.
6. Shielding has a slight delay to it.
7. After attacking there is a slight delay (recovery time) before you can block, to finish the attack animation. Duration of the delay depends on the weapon used. The last swing of a sword combo will have the largest recovery time.
8. Attack moves that are there are not always meant to be used. You can swing three times with a sword, but that doesn't mean you have to or you should swing three times. When you hit an enemy with your third swing, you cannot block for a short while, and that's when three other enemies hit you back.
9. Shield-bump. When you quickly tab your shield and then release it, you can knock adjacent enemies away. This can break you out of a crowd, and can be used even when your shield is broken.
10. Shield-cancel. Press and hold shield after your attack has been started. When you stop attacking, your attack animation will be cut short, and your shield will be deployed faster than if you press block after you stop attacking.
11. Learn the enemies' attack patterns. They will have additional moves when you go down a tier.
12. Try solo'ing. Enemies get more HP when there're more knights in the party. While you have to use energy to revive if you die (since there's no one to save you... just don't revive more than once), you can control the flow of the battle easily as there is no other knights to lead a pack of enemies into you. Take it slow, and learn how to handle a crowd. Then you'll do better in a party.
13. Not all charge attacks are created equal. Some of them are utterly useless in a battle (e.g. Cutter line of swords).
I disagree with Taz though... you shouldn't just buy your way into T2. Gears don't mean everything in this game - even with the best gear your HP bar will still evaporate in an instant if you get hit in T2/T3. Skill matters more than gear, and so you should spend some time in T1 honing your moves, or you might find yourself lying on the ground a lot in T2.
Learning the recipes is a one-time cost, but you can keep making the item afterwards. On days you don't have time to play you can spend your 100 mist crafting popular T1/T2 gears and then sell them in auction house. If you get lucky and get a nice UV, it will sell for a lot.
