THIS METHOD IS AVAILIBLE ONCE YOU HAVE COMPLETED ENOUGH OF THE STORY/REAL WORLD AREAS TO BE LEVEL 40 (although being level 50 is highly preferable for the store discount pin)Īs with the rest of the shop related achievements the best way to farm Psitanium to purchase everything in the Otto-matic and filling up the astral wallet is by having this set up: Thanks to the commenters for pointing these out. Other possible farming locations include the Pharmacy: Back Room (Hollis' Hot Streak), as well as the actual Collective Unconscious area itself. This doesn't unlock until Rank 52 though.
If you wish to speed this up, buy and equip the Psimultanium Pin, which doubles the drop rate.
OTTO MATIC SECRET FULL
Once there, just bounce around the nodes with Mental Connection until your wallet is full and the achievement unlocks. Equip the pin and, through the Collective Unconscious, go to either the Classroom or Hot Streak in Hollis' mind. This gives you a chance for 10 Psitanium every time you use the Mental Connection power. The first step is obviously buying the Astral Wallet at the Otto-Matic machine for 750 Psitanium and also the Mental Tax pin under the 'Mental Connection' category for 40. You'll need to be at least Rank 40 to equip the pins required for this method. You may get this one naturally but I've found a way to farm Psitanium if you want this as quickly as possible.
