 This document describes the challenges and solutions to creating a dynamic-expansion supported PEQ baseline.
 
-## Extend Expansion bit support
+## Areas of Concern
+- Load data based on expansion: Add a new expansion TINYINT(4)? to many tables to allow dynamic loading.
+  - aa tables: This is handled I believe with db_string? Verify
+  - account: This stores the expansion value per account, used by other tables.
+  - adventure_template: Since multiple expansions add different styles of adventures, add support for this.
+  - char_create_combinations: expansions_req contains this data
+  - doors: Does this need expansion? I'm leaning no, zone will determine
+  - global_loot: Does this need expansion? I'm leaning yes, as itemization should be determined with expansion
+  - items: may need expansion to ensure merchants are not populated with out of era items
+  - spawn2: need expansion to disable spawning of certain npcs
+  - spells_new: needs a way to discern expansion for allowing certain spells.
+  - starting_items: perhaps just honor if an item is of a proper expansion or not?
+  - titles: may need expansion?
+  - tradeskill_recipe: needs expansion
+  - zone: will not be able to zone into an area unless you are GM status or have the expansion enabled.
+- Quests
+  - Perhaps add a feature to prefix a quest file with an expansion to enable/disable it? Especially useful for things like player.pl/player.lua.
+### Combat

+```[PM] mackal: they used to have hardcaps on mitigation
+[6:55 PM] mackal: which was easy to hit during kunark as a plat toon
+[6:55 PM] mackal: plate
+[6:56 PM] mackal: they added a softcap, then shield going over
+[6:53 PM] mackal: combat system is basically the same
+[6:53 PM] mackal: mostly just a change in mitigation calcs
+[6:56 PM] mackal: then it basically stayed the same
+```

+    return (bonus - softcap) / 12 + softcap
+
+  return softcap # hardcapped for everyone else
