You found a little low health slardar in the river, you try to gank him. but guess what? he clapped you to death. sadge.

Here is a personal guide, from my old guide, just more complex.

I believe slardar do not build damage item like daed rapier, those r trash play.

just cast the ult then jump their support. with mostly 1-2 bash, they r mostly dead.

Please read on the item detail beforehand so you know what to disamble and upgrade to, dont make a silly build in the end and blame me.

Do rely on your team, dota isn't 1v1 game. Remember some hero ult like void chrono and jug omni do kills you and your ego, so build counter accordingly.
