Why does team attacking direct will cause BEL damage even though there is a rule that states team attacking causes no BEL damage?

Rule 602.5b If the attacker's ATK is greater then the defender's DEF, the defender's controller loses endurance equal to the difference between the attacker's ATK and the defender's DEF. This is called breakthrough endurance loss. Breakthrough endurance loss caused by team attacks attacking a character is reduced to 0.

Team attacks attacking Endurance directly hits for full force (Attack bonus's n all).

What AlphaOmega is pointing out is that team attacks do indeed cause breathrough.

However, when the target of a team attack is a character, that breakthrough is reduced to 0.

ahh ok thx
