I couldn't wait to level up my WD to 21. I really wanted to see my primary and secondary skill.
At level 20 I got my next passive unlocked. Actually paying a part of the skill with life instead of mana isn't that bad because that same passive gives a good life regen, which covers the life I spent on the skill right away. Plus I have a nice life regen in general. I actually started to love it.
As I reached level 21, I got the two skills I was longing for. :D Firebomb is just awesome! I can cast it from certain distance and it practically doesn't need any mana. I never run out of it (which is a different story with Zombie Charger). I can charge now like 6-7 zombies in a row, which is so handy when a big mob or an elite attacks me. It feels like those op-bears, but in smaller version. Locust Swarm, on the other hand, I consider as quite useless (at least at this stage) since it does little damage (it does lots of damage, but over time), and I can cast 3 swarms in a row only till I'm out of mana, which isn't good if I need some for my Spirit Walk in an oh-sh%t-situation (which I haven't had, yet *knocking on wood*). Practically, my WD uses Firebomb as primary and Zombie Charger as secondary skill.
He geared up for facing Belial and is nearly broke, with only 270 gold left (!). But my WD thought, that this is a good investment since he faces Belial, which he considers as the most difficult boss of them all.
My WD was only two bars away from hitting level 25, which would give him a new skill, Big Bad Voodoo. That skill would give him movement speed and attack speed. So my WD thought that it wouldn't be bad to level up the two bars before facing Belial, so that he can cast that movement skill when Belial starts to throw his green explosions at him, - which turned out to be so useful! My WD lost about 1/4 of his health during that explosions, but Big Bad Voodoo kept him moving. There was even no need for a potion or Spirit Walk (which he kept as Plan B and C). Belial is down! Phew! *still a bit shaky from the fight*
