Further Grim Dawn impressions. So the environments are semi-randomised, or rather the multiple connection points between areas are. The overall structure is always the same but how you navigate through one area to the next isn't. Enemies don't seem to scale with your heroes progression. So if you revisit earlier areas, you'll pretty much just one-shot stuff. Enemies drop materials which you can use to enhance gear on the fly adding healing, damage or resistance modifiers. You can combine these mats with two more of the same mat to improve the modifier you'll be adding to your gear. Even though there's only four classes (Soldier, Demolitionist, Occultist and Nightblade), once you hit level 10 you can choose to add a subclass to supplement your main class. You don't have to if you don't want to, the option is simply there.
