Low Level Spells VS. High Level Spells (firebolts, thunder bolts, ice bolts)

[Valen]

First of all, as far as Ice and Lightning bolts go, there's no change in cooldown regardless of what level you use, so I'd pretty much always use max level on these, unless you're desperate to save that tiny bit of SP.

The ones that change cooldowns are Magic Missile and Firebolt. For Firebolt, I ended up using level 1 up until probably low to mid 20s, and had no problems killing. For Magic Missile, I really haven't found any use in having anything above level 1. It'll basically be your basic attack, so low cooldown is a must.
