[@ActRaiserTheReturned] I am not the OP here, but I guess he meant more than just add a highschool sweetheart. Also your artifact is pretty uncreative to be honest. Especially greek mythology has so many artifacts you could use to fit your purpose. Just an example, one of the [url=https://en.wikipedia.org/wiki/Omphalos]Omphalos Stones[/url], [url=https://en.wikipedia.org/wiki/Aegis]something like Zeus Aegis[/url] or not to mention the ton of artifacts the heroes like Perseus used. 

[@Duthguy] I realize you already have artifacts but if you perhaps want something a bit more different or flashy than a sharp weapon have a look at [url=https://www.forbes.com/sites/kristinakillgrove/2016/05/26/mystery-of-morbid-aztec-skull-masks-solved-by-archaeologists/#3d1472e34d6f]this[/url]. These skull masks were apparently made from the skulls of great defeated warriors so perhaps your char could use one of them to summon the faceless spirit/zombie of its previous owner to fight for him. I just wanna make this suggestion because if im honest a especially sharp weapon is kind of boring and would be more fitting for a good of war. Also your char could still just wear a regular Macuahuitl. 

Sorry to you both if I sound like I dislike your chars. That is not the case, I just wanted to make a few suggestions.
