I just wanted to post an update. Here's some artwork from Tang Chan showing early ideas for two of our classes. The first is our Cleric, a ranged offensive and healing class who uses spoken language to invoke divine wrath.
The second is our Sorceress. She uses the blood of ancients to tattoo glyphs of the divine language onto her person and then uses them as a twisted version of the Cleric's spells. She's a melee caster that uses debuffs and direct damage spells to bring the pain.
Cheers!
