I am about to play an Echo Knight in a game, and have been doing my research. The gist of my understanding is that Echoes are unable to make grappling checks, and I am prepared to work with this. The knight, on the other hand, is still able to make grappling checks.
Grappling requires a free hand, and two-handed weapons require two hands to make an attack with them. When an Echo Knight makes an attack, the attack can originate from the Echo's space. If an Echo and the Knight both are wielding a two-handed weapon, and the Knight successfully grapples an opponent, are the Echo's hands considered free to make a two-handed weapon attack?
