Shadow Clone is quite a useful ability. Just imagine being in a battle and suddenly having an extra opponent appear, causing confusion and despair. Additionally, it can be used for exploring dangerous places. Waldo was quite satisfied with this ability.
He continued to use Shadow Clone several times to become familiar with this ability. After about an hour of experimentation, he had a preliminary understanding of it.
Firstly, the Shadow Clone was created from Waldo's shadow, and he could have only one at a time. Secondly, the Shadow Clone possessed some combat capabilities, roughly equivalent to 30% of Waldo's strength.
Thirdly, the Shadow Clone couldn't stray more than a hundred meters from Waldo. Lastly, if the Shadow Clone was destroyed, he needed half an hour to use this ability again.
