What I've noticed, these islands are all worth going to if there is not a node on your island (personally i use the main island and branch out if I see a node while there is not one on my island or a better node)
Node order to look out for:
- Fleshy growth > Fire storm > Fireball > Vine > Rock fragments
If there are any lesser than this, I stock on rune essence from body esshounds and the mind esslings due to not getting any mind runes from the nodes I'm siphoning.
Hope it helps, any corrections welcome and appreciated, thanks to all. ^_^
