Basics:
Use Orb of Storms + Spark early to get used to it
Swap to Orb of Storms + Arc at level 12
Optional: Swap to Orb of Storms + Lightning Conduit at level 28 at least (but only after Lab #1 for 100% Shock Uptime from OoS)
Optional: Swap to Orb of Storms + Crackling Lance at level 28 (I wouldn't suggest this until maps, but you can do that)
Orb of Storms can be used interchangeably with Storm Brand for Lightning Conduit, see what feels better for you.

======= Levelling =======

Levelling trees are provided for 1st, 2nd and 3rd lab on the guide and here. Make sure you check them out by switching between the available trees.

Basically, Elemental Overload for 40% More Damage, and Non-Critical Lightning Damage is Lucky from a Mastery, that should carry you to maps.

Levelling doesn't revolve around crit or freeze. We only transition once we start mapping.
Transition to Freeze happens (usually) when you get The Three Dragons and get to maps.

Take this with a grain of salt, but if you're new to the game or playing casters, it's good advice.

======= Mapping =======

Once you hit maps, you want to gradually swap to crit rather than non-crit once you have the gear, and start Freezing.

That means getting The Three Dragons, and better and better gear.

Leveling with Arc should be fine, though at some point you're likely to feel you need more DPS, and that's where Crackling Lance comes in, or Lightning Conduit.

I don't recommend wasting time on trading for rares while leveling unless you really feel stuck, but feel free if you enjoy that.

Agnerod West should be a very cheap mapping staff if you want one.
