General Changes

This page lists an overview of changes made in PD2 relative to the vanilla game. Topics which are too detailed for this list include links to other pages with additional information. Also see: All Topics

Skills
All skills have been reviewed and balanced (or reworked if necessary) to ensure each has a niche, and some new skills have been added. The Skill Overview page lists changes for each skill. There's also a Skill Planner for PD2.

Individual Items
All unique, set, & runeword items have been reviewed and balanced to improve itemization options, and some new items have been added. See All Items for a complete list.

There are also several new non-equipment items. For example:
 * Worldstone Shard and Larzuk's Puzzlebox can corrupt items and add sockets to them
 * Jewel Fragments can be stacked and used like jewels in recipes
 * Maps allow access to new endgame areas (23 total new areas)
