It's another update from this lovely game.
Giving us, the audience, the opportunity to design a healer is quite and honor. Based on the required characteristics, I will suggest that the healer looks something like this:
headwear: a headband made of tiny noticable rocks and natural things. Reason: healers gives life and nature is life.
eyewear: none. reason, a scanner should be cool but scanners look better on warriors because they are in the war front. A glasses will make our healer look like an old man with myopia which is not cool.
clothes: should include sweater with good design of green color, should not look as futuristic and flashy as that of the warriors.
background ideas: this should be depending on the color of the healers skin. A black and gold background would be good for a healer with white skin.
Thank you
