In recent times I too have been attacked during mutual challenges amongst
these include Blueskull, Psy, Arkamedius and even Sir Yousuf.
By attack I mean physically jabbed, from Zenichiro's post, the most offensive
attack you refer to seems to be 'get rune' which isn't very offensive really
So sure. it is easy to type challenges. Whether he needed to or not (since he
didn't attack) is the question you should ask.
