Drop Rates and Difficulty

2x Experience Rate for both base and job experience.
2x Logarithmic Drop Rate. This means that 'rare' items recieve more of a boost than 'common' items. For example, cards recieve the full 2x, making the basic card rate 0.02% instead of 0.01%. However, common items recieve a smaller boost: A jellopy drops at 74% instead of 70%. This helps keep the economy balanced by making monsters (relatively) give the amount of resources they were meant to.
There is a 5% exp bonus per person for exp-share parties.
There is no penalty for death.
Quests are required for all job changes and platinum skills.
The novice training grounds have been removed.

NPCs and Services

There is no warper, but the official Kafra Warp is still available.
There is no healer or inn.
The only Reset available is for new characters before they enter the main game world. It allows you to reset your stats with no stat higher than 9, the same as creating a new character, but without opposing stat restrictions.
There is no skill reset available.
There is same-sex marriage, at the usual cost.
Guild storage is accessable at any time for guilds with 'Contract of Kafra', by visiting Kafra Headquarters in Al De Baran.

Database Reverts:

All Mobs have stats from Yuno Episode. This means everything, including experience.
All Drops are based on Yuno Episode. This means that the anti-inflation patch is not yet implemented. The patch reduced the drop rate of some cards and other rare items, among other things.
Mob skills are between Turtle Island Episode and Yuno Episode. MVPs all have the skills they had at exactally the TI patch, which means no 2-2, equipment breaking, or full-screen status skills.
Some Items have had their use reverted. Most noticably, the icepick no longer grows stronger as defense increases; it now only ignores defense.
Item/Card Combos no longer work. The only item affected was the pantie / undershirt combo.
MVP exp is as it was at Yuno Episode. This means MVPs give about 10% of their total exp as an MVP reward, 50% of the time.

Mechanic Reverts & Fixes:

There are no 2-1 or 2-2 quest skills.
Alchemists cannot have Homonculus.
Alchemists cannot brew Slim Potions.
Acid Terror will not cause bleeding.
There is no ranking system for forgers and brewers.
Poison is no longer removed when your health is below 25%, though it will not continue to drain health.
Bowling Bash now pushes back farther at higher levels, matching the skill description and official behavior.
Backstab does not cause its target to face the user automatically inside PvP and WoE, allowing for consecutive stabs.
Like on officials, Monks are now able to use combo skills during skill delay of previous skills, rather than needing to use the skills at the exact same time.
