lol, you people ask, I answer, lol.
Y do u waste the time? That much free time? Tisk tisk.
1) It only takes like 30 seconds
2) Yes, I do have to much free time, but I"m just fine with that.
Be warned that the snow queen doesn't combo.
Both the Frozen shooter and snow queen freeze 100% of the time when the special hits. The snow queen can hit enemies in a line and it also freezes them if they block.
They both freeze you randomly, but its very rare and you don't really need to worry about it.
So it is better to not upgrade it huh?
Advantage of upgrading
Hits enemies that are grouped
Freezes even if the enemy blocks
Disadvantage
Can't combo
You can take my Snow queen for a test drive if you like that way you can make up your own mind
