Crystal Energy
I have been playing spiral knights recently and noticed you pretty much need energy to do almost anything..... So i was like "DAG DABBIT DAMMIT DANGIT" until i found out i could BUY CE for a good price (at least it is to me) so i was like "YEAAAA" and bought a bunch and now im going to buy more again............. Im buying alot this time! WOOO
Damn it spiral Y U MAKE ME ADDICTED.
How much money have you guys spent on Spiral Knights!?
I dunno how much ive spent... Maybe i dunno alot O.o

I don't buy CE with real money, but I think I put at least a good 100k crowns to make it to T3 and 2*-3* costumes and weapons. No money for me, not while SK is completely free (Besides the time frame frenzy). So far I've been playing fine without the money of mine.

I payed $10 on the first Rose Regalia event...
I gave the costume(It was the White Armor) to my bro for his birthday...

I'll admit to having spent $15 (well... a tiny bit less since SK insists on xx.95 on all their prices) on CE (which amounts to about 4.5K CE), which got me a Wild Hunting Blade, a Pulsar, and a decent set of armor for T2. Then I used the rest on a Silver Key and got a Regal Bomb Bandolier out of it, which I sold for 4K CE, and that should be enough for my crafting needs once I get the necessary recipes for 5-star items.
...but mainly, I just wanted that Wild Hunting Blade.

Probably $100 over 4 months.... not bad for the price of 2 games.

15€ but for now i'm not going to put money into it because they are ripping of european players :(
it's better i buy a game on steam and trade THAT for CE...
Lol. Are you going to share? =3
Also, not knowing how much money you spent on a game is a bad sign...
