Put in Socket and Stat Enchants
Enable the Socket and Stat Enchant NPCs for the gear we currently have access too.
These enchantments were added in late into the episodes as an attempt to make most irrelevant pre-trans gear viable again. Adding these in before the proper release date would do the following:
ZENY SINK (pretty obvious one)
Mid tear weapons become viable again. Examples - elemental katars, infiltrators, zweihanders, gaebolg, orcish axes, elemental books.
This promotes more viable builds for classes. Examples - Sonic Blow Sins and Auto bolt Sages which are currently lacking due to gear availability.
+3 stats in an armor really doesn't affect your current build unless you're a min/max player. In addition 3 stats doesn't have a major impact in any build. Example - You get 3 str from your armor, you get to recudce your base str by 3 and allocate those points into something else which will probably end up being 1.0 more aspd or a bit more vit. Not really game changing.
Finally, It makes Hat of the Sun God actually useful before trans hats outrank it.
We already have some trans content, if you think about this with an unbiased view point it actually makes sense to put it in earlier than its intended release time.
