In this video, I show the pinnacle of what can be achieved with the Back to Basics Keystone.

The issue with this keystone is that the maps don't typically have a lot of mobs in them. We get around this by running a 8 mod conqueror map and we use 4 scarabs that increase baseline mob count with x1 40% more magic mobs, x1 all mobs are magic, and x2 4 additional rare packs.

Lastly, since these maps are extremely juicy, I only use conqueror maps that drop good divination cards, which is why I am running it on Defiled Cathedral for the mirror shard card.
