There’s nothing to copycat if you farm a-shots from Himfjäll. Latter place is littered with a-shots and one can easily get 100+ a-shots by hitting each and every loot box/bag at Himfjäll. Wait 4x in-game hours for loot boxes/bags to restock and repeat the process.
I haven’t even bothered to pick up a-shots anymore since i have more than enough.
Vanilla island, in the other hand, doesn’t have much a-shots to go around. Most what i’ve gotten from single POI is 6x a-shots (Hermelinen), while the usual toll is 4x, if even that.
Speaking of a-shots, i currently have 218x a-shots between all 4x of my chars and Plundra. And i too have given away plenty of full stack a-shots (20x). Always as a donation if i see the player in MP doesn’t have any and would need some (e.g we have a battle, he/she drops down and t-ports back to safehouse). Next time i face him/her, i drop one full stack for him/her.
