hi im lethal proc (user name is old name, ignore that)
this is just a quick guide for mordekaiser, i hope you like it and try it out before trashtalking

what you want to do as a morderkaiser is farm, basically aim for the 100 cs mark at 10 min
if you can do this you are super well farmed and can basically do whatever you want (dont exaggerate^^) once you are starting to snowball start taking objectives such as dragen and start helping your team more, remember you have no cc so let your jungler gank and only leave your lane when you are 100% sure to get a kill.

the item build is pretty straight forward, you get boots 3 pots for the survive and mobility early, then when you have 850-1000 gold push the lane so you wont lose any cs (hard to do vs f.ex morgana, brand, ahri, then get your jungler to take over the lane exp so nothing goes to waste) then get a kage lucky pick to get that extra gold, and you also want to get extra pots and either 1 or 2 wards, depending on if you are getting camped or not. continue to get vamp scepter and then proceed to become a immortal and laugh at your enemies. then proceed to get the suggestions i've mentioned and remember to spam laugh.
