Diablo 3 season 19 best farming spots
While farming a spot on the map with a high amount of weapon racks is a good idea, you always will want to keep building your Death Breath supply. The thing about Death Breath's is that you can easily blow through them when you're trying to obtain a certain item.
If you're having problems with white materials, then I'd say to focus on one specific location, but the problem with that is that you may not earn the shiny upgrades you seek. This will cover blue and yellow materials easily. Mainly because they can cause shrines to spawn elite mob packs and will provide you with more drops, and faster clear. If you're also not fully geared, I'd highly recommend doing regular rifts, and attempt to get a copy of the nemesis bracers. Bounties are good for legendary extraction, and patterns as well, but may not be as fast for materials if you prefer to play solo as many of us do. Pick something that fits with your path and character build more than anything. This means that farming for gems is mostly a waste of time.Seems to be a mix of responses here but people may assume you can run this/farm that.
At the beginning of Act II already, they're dropping mostly perfect gems and if you're lucky, radiant gems. at the beginning of nightmare difficulty, monsters still drop mostly flawless or normal gems. If you spend a noticeable amount of time in one area just to grind for gems, you're most likely just wasting you're time, because the same time spent on advancing in the game will get you more higher quality gems earlier on. As far as I'm aware, there are 17 of them. The thing with gems is that there are a lot of different quality levels with them this time around. Basically, you're up to your fortune here in how lucky you are to find gems.
This does, of course, mean that special opponents such as champions, bosses, or the treasure goblin have a higher chance of dropping them, but unfortunately, I don't think there is a place with tons of champions always walking around. The best way to minimize the time needed to get higher quality gems (which is ultimately what you will go for - even if you want to farm low-level gems) is to go to higher difficulties as fast as possible, since stronger enemies will have a higher chance of dropping higher-level gems.
