I am still in act 1. Fun so far. Feels like the usual arpg that is just slow going at these levels. Have to kite bigger packs. Only a couple things seem to give me trouble. There was these knights in a mausoleum that reflected every shot at me and those reflects did crazy dmg. If I got them with a bigger pack of mobs, or those abyss invasions it was alot of kiting. If they were alone or in a small group of mobs, could get melee and shoot, dodge, shoot, dodge so they didnt reflect anything. The other thing is occasionally getting corned by a ton of mobs and you are just stuck and better pray you can kill fast enough before you die. I assume later you have movement abilities like teleport, leap or something to avoid those situations.
5k gold so far, been able to buy any upgrades from vendor I find. Even some yellows.
Does it just get rougher later? Usually the first couple acts are the slowest and things just speed up from there.
