For Myth, who is, in essence, already a Blademaster, he is already an accomplish fighter. His Relic would just allow him to target anyone he feels within his eyesight, and strike them down as if he were Zeus. 

hehehehe.

He would already be equal to a Relic-enhanced fighter, and he has a ranged instantaneous weapon of varying degrees of POWAH

I tink the foreign non-Otheian-speaking weapons master would fall quickly. Myth would identify him by his armor and his buddies that he is a foreigner, and then recall his stories and what his father told him of the world, and realize that the foreigner is allied with the Church, and so he will attack him as if he were the Church. Should Marcus attack the foreigner as well, I would think there would be a momentary mutual agreement between both Evokers as they take down the Relic-hunter Foreigner.

Jessssssssssssssss
dat would work ::3
