Yes, you can use up to 2 MCS + main character, so total you can be logged in in 3 characters in same time
remove that shit, add runes in shop.
Sure, it'll look good on otservlist due to atleat half of the players using MC, but the true tibia players wont bother to play due to mc farms in every fucking city.
And NO, you can't just "kill the botters" because they always stack down in caves and put a fuck load of items everywhere so you have to get a backpack of the remove item rune to just reach them.
