Has anyone, or could anyone list each item's first possible access and requirements?
The main thing I saw when my brother was playing through was the cliff in Zi that blocks access to the previous areas. It'd be great to know how to get everything before jumping the cliff, and which items in each area require which upgrades to access.
On the wiki pages, the hidden items should be spoiler-tagged out with links to the prerequisites or locations if obscured by landscape or require enemy corruption.
