The art of the comics received noticeable upgrades at least twice.
The first was in Comic 198, "The Great Kazoo", where Elan and Haley both break the fourth wall to show awareness of the upgrade. Elan gains a clasp for his cloak, Roy's boots are more orange and a bit more detailed, Vaarsuvius' cloak has some red runes on the ends, and Durkon's holy symbol is now a bit larger with a green gemstone inside it.
The second was in Comic 947, "Keep in Mind", most noticeable by the different comic font, higher resolution and overall more detailed art. Particularly noticeable are the rain effects, far more detailed in Comic 948, "Behind the Eyes than in previous stances such as Comic 201, "Seeing Signs.
The Greenhilt Sword is also noticeably more detailed, particularly in the cross pattern in the hilt. Colors in general show more variety and subtlety of nuance. Even body types are more varied, as show in Veldrina's more slender body type.
The text font has been changed as well, from the infamous Comic Sans to Wildwords Lowercase from Comicraft.
