I've recently been looking at the magic phase and how best to use it and, after rolling 11 for magic dice and the level 4 going on to fail the first cast, thus wasting all those dice, I've been wondering how multiple level 2's would work out. Usually I only use a Level 4 which get gets a +4 to cast and dispel, so that's pretty good, however, the level 2's would get 3 dice to roll for channelling, you would be able to continue casting after a failed cast, would have more position across the board for magic to be used, more access to arcane items, plus you'd have all 6 spells in your lore available across the three. Not counting signature spells of course.
So, does this seem like a good plan, or is a level 4 a better pick regardless of its disadvantages? Has anyone else tried multiple level 2's over a single level 4?
