HTHA & Move-Throughs

[Zan the Gamer]

If a character buys a Hand-To-Hand Attack power and defines it as iron fists, making his punches more powerful, can he also use that Hand-To-Hand-Attack power when performing a move-through or move-by?

[Steve Long]

The rules for adding damage via movement are on 5E 271. It's up to the player to decide whether a particular special effect of an attack should or should not work with those rules, and if necessary and appropriate to Limit the attack accordingly. And it's up to the GM to make him Limit it when it should be Limited, but for some reason the player doesn't do so.
