I'm really confused with this post.
First of all how do you know it's spamming THIS spell during 10 minutes (where nothing goes wrong) that makes the server crashes ? Could be anything else another player has done. And why should it crash after 10 minutes and not 9 ?
Is it the only spell that does that or basically spamming any spell has the same result ?
And i don't think it fit in this section, exploits are for live exploits, you should post this under Emulator Servers i guess. Edit : my bad, it's the good place
