so i recently started playing dota... actually so far only twice ... but im in love with it still... i suck... -__- so i was wondering if any of you could help me out... i know this is pretty vague but to be more specific which buttons do i use to get my skills ?_? for example i played slithice and all i new how to do was attack (by pressing a) and put my opponents to sleep (by pressing g)... besides that i was clueless and basically brought my team down so if any of you can help me or direct me to a website that would be great
