The most successful prop in DOTA (including DOTA2) is the prosthetic leg, which is known as the extreme ball of the Handspeed Party. This prop can provide you with moving speed, attack speed, important attributes in the early stage, and you can also switch attributes according to your different requirements. It can instantly increase the HP limit of nearly 200 for you to avoid when you gank, and it can also provide you with a higher attack speed for your rapid development, or release key skills when you are blue enough.
