I just encountered a very strange bug involving this card while duelling against the Reverse Trap Standard Duelist. He equipped Shooting Star Bow - Ceal onto my creature but on my turns I could not attack his life points directly? (Even on Auto-Duel, my character did not attack.)
Later in the duel he equipped his own monster with a Star Bow and he didn't attack me directly either.
There were no other cards on the field preventing us from attacking.
Thank you for your information. That is exactly wired. Although I am not sure why that happened and I cannot fix it since I am not an official developer, this comment will help you other players who encounter the same problem.
"The equipped monster loses 1000 ATK, but it can attack your opponent directly."
This is so horribly worded/misleading. The subject is equipped monster, "it" should refer to the equip monster, therefore the opponent is whoever is opposing the equip monster. Not the owner of the bow's opponent.
