So, i'd imagine this has been asked many times, but searching is a bitch, so here goes. I've just beaten doflamingo on island 4 and have no idea where to go next. I have a bad feeling i'm going to havw to go back and do heaps of developing to get the better bug catcher net. SO yeah, where about's do you go after the first boss on that island? kthnx.
Island 4, especially for those without Ep1 data, is just a complete and utter brick wall most of the time.
This is a bit lengthy, but bear with me -
Firstly - You'll need the idea for Advanced traps first - it's treasure 1, found on island 1 - map pieces dropped by mud puppets -
If you need to get map pieces, the easiest way is either to use Nami's Ep1 whirlwind attack, or your net - swing it at the enemy who drops the map piece, run away until they disappear, then rinse and repeat -
For Advanced Traps you'd need
Enhanced Traps
–----------------
x1 Sweet Sap
x2 Nectar
x3 Iron Scrap
Sweet sap you get as a drop from catching a bug on island 2
Iron scrap from any sword-wielding enemy.
Next, you'd need to try and get the advanced pickaxe - you'll probably get the idea either by swinging your pickaxe at one of the big purple rocks (which will break once you swing with the advanced pickaxe anyway), or via checking one of the monuments - you'd have to check Usopp's building tech tree to see if you've got the idea.
Enhanced Pick-axe
x7 Diamond Fragments
x3 Mysterious Parts
x1 Wood
Mysterious parts drop from PX1 (and they drop map pieces of the Advanced Vacuum - Treasure 8 - which you will need if you plan on facing Whitebeard and Garp) on island 4
Diamond fragments are dropped by Enel's Spacies on island 4.
Finally trying use your net on the electric Spiders on island 4 will result in the Idea of the Advanced But Net
Enhanced Bug-Catcher Net
x3 Pure Iron Ore
x5 Mysterious Parts
x1 Bamboo Sprout
Pure Iron is the drop you get when you either catch a Mole on island 4 (I believe you won't be able to access any of these before you break a certain spider's net... ) or from the giant purple rocks on each island.
Mysterious parts - PX1 again... Swing, run, respawn again...
Bamboo Sprouts are the 'thin bamboo' from island 2 - just before the first Pacifista cave.
========================
It's funny because the Dev's of Unlimited Cruise Ep2 expect people to figure this out without any hints at all -
But a rule of thumb for Unlimited games -
** Find every treasure you possibly can as soon as you can
** Read all the monuments possible (eg explore everywhere)
** Cook each dish and give it at least once to every character.
And for anyone having issues with fishing lists, ingredient lists for things etc
