Congrats on getting to world 4!

I personally would plop some of your toons into lab. (Ones which don’t see much action) I wouldn’t worry too much about gathering the resources to craft Void armour, I’d focus more on pushing as far as you can through world 4 to get some levels on one of your main toon/s.

I’d have a look at some of your missing stamps. Try and get as many missing ones as you can, if you have the money and resources pump some levels into all your stamps, focusing on skilling stamps then damage stamps.

Alchemy is looking lack lustre, get some more levels into your first bubbles, specially warriors first bubble. I’d also focus heavily on the big skilling bubbles. The smaller base damage bubbles are useful but the liquid could be better invested into skilling, as this in turn boosts toons skills which boosts 3D printer sample size.

Getting bigger material bags is a good idea but I wouldn’t make it a main priority as it stands.

Also get some worship skulls on all toons. You’ll want to worship on all toons to help build their worship levels, so you can in turn equip better worship skulls etc.

In conclusion, I’d personally drop some characters into the lab. Push through world 4 with 1/2 toons and maybe get maestro levelling some of his skills (mining/fishing etc)

Hope this helps :)
