Okay the´re some mistakes
FRIST: Warmog´s its an iten MADE FOR MUNDO dude health and health regen --> MUNDO
SECOND: u cant put an iten that increase the health regen,LS,SV... without at least build some really health regen( u can get it with force of nature btw)
AT LAST:
- doran´s shield its a very poor iten for a build u can replace it for some health regen like a philosopher´s stone wich ill give u extra gold and can be builded later into a shurelya´s reverie that ill give u CD and health
- the frozen mallet its kinda useless since with some CD u ll spam pure CC with ur knife
- the Wit´s end ll not help u , mundo dont need AS u can replace it for an Artma´s Impaler wich ll give the AD u need
uff... =^ i guess its enougth keep updating the guide, dont give up, this s just ur frist guide =)

Good luck on your first guide. I upvoted to make up for the trollvote, but you should consider enabling "Require comment to vote" (it's above the Publish button when you edit) so you at least know why people don't like your guide. Also I have to warn you that you're gonna get a lot of hell for not including Warmog's Armor since it's pretty much a core item for Mundo.
