They technically can. I had a conversation about this matter a few hours ago with Biatch, who is an INT priest himself, from what I’m aware of. Your suggestion, though, is an interesting one. An item as in?

Thank you sir

it's normal.

@nikos32   I used (2) plat bars yesterday, had both on me. First one gave no reward, second gave a reward. Is this normal to get nothing or is it a bug because I had (2) PB on me? 

I thought the issue was that as long as you have both Premium Styx and normal Styx in your inventory and you use only one, it would drain 2x 3000 MP. But that’s not the case here. They need to use both in order to drain 6000 MP. Also, the Styx cooldown here is 11 seconds, unlike on other servers and official, where it is set to 5.5 seconds. So, what's the actual problem?
