Well i have some questions about something...mostly at all of my games i see players making 2 same item but for me some items arent sstucking..for example 2 hyperstone...2 butterfly,3bashers (non bash hero),!Are these items stucking together?If yes what other combination can you propose...!

How about you actually write so people understand what you are asking about?
Yes, 2 hyperstones stacks, 2 butterflies stacks, but the evasion on the item doesn't stack, the stun effect from basher doesn't stack.
The same applies for most items with some exclusive effects like Mjollnir, Maelstrom, Monkey King Bar, etc.

I am sorry man i am greek first and second i am sure they will understand just like you did!Thanks alot though!

Bashers doesnt stack, butterfly's do stack but not in the way that it just stacks upon eachother, its a percentual difference and yes hyperstone stacks

Yes , 2 hyperstone it stuck , but why u spend gold on 2 hyperstone.. better Butterfly ;) .. 3 bashers stuck but i dont know are they working... ;)
