The entire notion of honor and the unspoken rules of combat between Cultivators was entirely unknown to me and something I wouldn't really care about anyways, so with this opening being presented as Evander clawed at his head and faced away from us... well...
With no other enemies present and no real reason being provided as to why I shouldn't attack him right now, I lunged forwards and swung the halberd down towards Evander's skull, any brief hesitation I might have had fading completely when I heard the almost inhuman groan escape his lips.
Not only was this someone who had done one hell of a job at getting under my skin, but he was also now under the influence of whatever dark manipulation that the figure had placed him under, so I wasn't wanting to take any risks.
