Sell Price: 1
Notes
It uses the lightning animation instead of the normal nature animation.
Has traveling time, so can be combined with [Chain Lightning] or a Shock which are instant for spike damage.
Tips
This is a good spell to start fights at lower levels. Untalented and used against a foe with no speed boosting abilities at max range, you can cast 3 Lightning Bolts in the span of time it takes for a mob to reach you. You can even cast a shock just as the third Lightning Bolt finishes casting to max out damage against a pulled, incoming mob.
It is also more likely to use during combat because of its 2.5 second casting time as opposed to other classes' similar function spells and is fairly mana-efficient.
