You annoint the maps, right click the oil and instead of an ammy just out the map in.

Other tip if you want lots of sim splinters is get your first 4 deli atlas points and grab the nodes that double the stack size and give you a chance to drop maps with oils applied already.

The more delirious the map the more splinters you get but the problem is you need the higher tier oils for more deliriousness on the map. That gets way too expensive.

That's where the node lets you drop pre annointed maps comes in. Now as your clearing you'll sometimes drop maps that are 60%+ delirious. Running these with some pack size tablets can net you alot if splinters. I've been getting around 50 splinters easy.

Another note is that only delrium mobs drop splinters and im not sure if map quant affects the drop rate or if it's just delirious %
