If you have just started playing an archer in Perfect World, then this is the portion you should read. Some newbies asked me what best weapon to grinding is. I was reading several forums. Many players think Slingshots is the best weapon.
Slingshots are the best for grinding Perfect World Gold. Ideally you would want to find a mob that you can auto attack until dead and oddly enough a slingshot has the fastest fire rate and does this the best.
Do not say crossbows have a slow cast time because that is the wrong word. They simply fire slowly. Channeling a skill bypasses this fire rate thus making a crossbow superior in PvP whatever. As soon as you're in the PvE scene grinding, the slingshot outshines by a mile.
The legendary 42 sling is probably the best thing you will ever come across at that level up until mid 50s to late 50s. At the current level, I suggest you get a decent level 35 giant crossbow. This should be swapped out for the legendary 42 sling asap.
Now as for why slings outshine the rest - the auto attack speed of a sling is a lot faster. But this ONLY affects auto attacking. And since I mentioned that ideally you want to do nothing but auto attack, then the sling xbow. True, the xbow has a higher max damage, but that messes with how you respond to situations. When you grind, you want everything to be so similar and predictable so that you can become more efficient. Basically a crossbow has unpredictable damage. I've crit 12k before, and then crit 4k shortly after, same weapon, same mob.
