I agree with that. Crystal Lightning Wand it is, but....hmmm. If I calculated correctly, the max mana reduction with the gem upgrade will make the first charge cost 23 mana? With the speed upgrade, the first charge is around 32 I think...in the 30s I'll just say. Any opinions on which path is better?
Normal = 3000dmg, 17.5s, 110mp
(
171.43dmg/s, 27.3dmg/mp, 6.3mp/s)
151 Mana Cost = 1950dmg, 17.5s, 66mp
(111.43dmg/s,
29.54dmg/mp,
3.77mp/s)
178 Speed Cast = 2580dmg, 15.4s, 92.4mp
(167.53dmg/s, 27.92dmg/mp, 6mp/s)
Is this the comparison you were looking for?
As you can see, upgrades for the Crystal Wand will always reduce damage over time. Both upgrades will increase damage per mana (though not by much), as well as mana usage over time (not significant for speedcast). Speedcast comes in handy because you don't want to be stuck charging for too long if things are swarming all over the place (if you had idle time then Fireball is way better). On the other hand, mana reduction is good for anything except finishing the task quickly, as it'll boost your mana efficiency for both damage and time.
Though, you could get a cheap -16% mana Lightning Wand at no damage or speed loss, so it still has some use.
