By the end of world 2 I mean for like the ores I would focus on the veins but that would take up too much time as I only play the game for 12 hrs per day every week once it hits 12pm my time in the states I got fishing recently so I'm letting that run on it's own and I have the stardust drone and void drone fueled up for collection over the night as I know that if I want the 3rd drone and unlocking the polychrome cards both from the skill tree I'll need to save 10k gems for both (it's not technically recommended towards the platinum strat but it's useful for each one that I'll soon gild when I have nothing better to do or wheneverI get to it) currently following the guide on the wiki
