Quick question. I have a 20 wizard and was wondering. Is mana regen this slow on purpose or am I doing something wrong? I blast a few mobs then have to sit down for 10 minutes while I wait for my mana to come back.
How many nukes does it take you to kill the mobs? Are you using blessed spiritshots? Basicly you should be able to kill mobs around your level with 1 or 2 nukes. You could try using a combination of Blaze and wind strike and see if that's enough to kill the mobs, thus saving a bit of mana. But yeah, mana regen is a bit slow for you, gets faster at lvl 25 though when you get Body to Mind skill, if you bother to use it.
Hunt in places where herbs drop, mobs that are white/green to you and you can 2- preferably 1-shot them. Thinking where I was on dark wiz at level 20 ... I think neutral zone, Abandoned camp (lots of PKer may roam around but you get XP back), and as human you could try to hunt mobs that are weak to fire - mostly plants and bugs are.
Windmill Hill (the spot marked by 'm' letter of the area name on the map, hunt Poison Spiders first, and Vuku Orc Fighters while spiders respawn). Neutral Zone (Lycanthrope) and Ruined Bend (Ratman Warriors, but I'm not sure if there is a place with good respawn) can be good too.
