You will certainly have to check this note (major note, about Arcadia update) to see every detail, about how they work now.
Also, there's only one free Scroll given from a Quest of Gato, to reset your Elemental Points.
The only known change on a Set bonus that happened, to me, is this one:
Removed the "Attack Range" stat from Earth Master's Secmathian Set (3 parts) and replaced it by a different one (all grades: normal, rare, hero). We found out that this ability is bugged when used on sets. If you have any problems with this ability on other items please let us know.
If you've been off for literally a year, here's a list of changes I consider as major, copied from the notes, starting from April 6th 2016:
_Added a fix to prevent menus from closing and chat from losing it's focus without a reason. Please let us know if there are additional cases where this happens.
_Added an experimental Fire Element Dungeon fix. It worked perfectly fine for our testings (in a party and solo).
_Several cutscenes in Verdurous Forest can now be skipped by pressing ESC.
The "Flinch" effect will be removed from chain combo attacks and the chain combo modification skills (Diffuse Cannon, Double Shot, Smart Shot…) in PvP. This change does not apply to the PvE gameplay.
Chain Combo Changes
· The option whether Chain-Combos are enabled or disabled is now saved character-wise and no longer client-wise
· The Chain-Combo checkbox location has been changed in the UI from the top of the Chain Combo overview page to the bottom (see image below)
· A new option for the Chain-Combo behavior has been added: Fast X-Attack
For this another checkbox has been added on the Combo overview page next to the Chain-Combo checkbox (see image below).
If this option is checked, holding down the attack key (standard key 'X', X-Attack) results in a fast constantly attack of the first X-Combo of all classes. This does not affect the usual manually "X-Spamming" or the execution of chain combo combinations.
The attacking speed respects the character's current attack speed.
Important Note: For the mage class the attack is slower when holding down the key and walking at the same time, but still faster than before. This is done on purpose, because the mage class is the only class which is able to walk while x-attacking.
This new option only works if Chain-Combos are enabled and is greyed out if Chain-Combos are disabled!
The option has been added to offer all players similar attack speeds no matter if macro hardware is used.
_The Repair All option is now the default option if using the repair function of the blacksmith
_The max. Level for the mission maps Dragon Valley and Edge of the World has been raised to level 85. This has been done to make farming and getting ranks (for example to do the daily quests) easier for end-level players. This applies only to Arcade (F1) and Chaos (F2) modes
_The limit of 100 for stack division has been removed, now you can divide stacks in any amounts
Vaults, Vaults, Vaults
Good things come to those who wait. Finally you will be able to obtain the Guild Vault Expansion from the Item Mall (permanent) for 500 IM Points per additional Guild Vault Tab. But that is not all! Every guild will get it's full first guild vault tab made available completely for free. Also every newly created guild will get a full first guild vault tab after getting the guild vault from Dony.
But this is again not all! The Character Vault Expansion (not the account vaults) will be permanent in the future. Just buy an additional tab in the Item Mall for 300 IM Points and you will get the additional space permanently. Please remember that the character vault is extended per char not per account.
Added the Happy Jobchange! Quest for the 3rd Jobchange where you can obtain the Jobchange Box from Dustin at Village of Ash Mist.
_Galaxia Skill Socket Cards are now usable from Level 20~99. Card upgrading stays untouched at NPC Crete for the time being
_All F6 Rings are now socketable (also the lower level ones)
Drop Rate Adjustment
The calculation for the monster drops has been reworked to make the dropping fairer. Instead of continuously decreasing drop rates with increasing difference between player level and monster level the decrease is now occuring in steps. One step is always 5 levels of difference between player level and monster level. Please refer to the tables below:
Comparison chart between drop chances before and after the maintenance
Please keep in mind, that the items themselves have an own drop chance which has to be taken into account. The charts below show 2 different examples of the old and new drop chances.
Drop chances in case that the item has it's own drop chance of 50%
Drop chances in case that the item has it's own drop chance of 3% (Silver Coins for example)
Mini Update to the Game
You have unlocked the Arcadia Episode 2 Mini Update and now we will reveal what it is: a 3rd Equip Page only for cosmetic costumes.
Ever wanted to have your personal look without missing out on stats? This is now possible. Just wear a costume on top of your IM gear (for ex Devil's Set of Agility or [Best] Unity Set). You're now free to create the look you want – mix and match whatever you like! You are now able to look as you want without giving up your stats. Every IM costume piece is working on both IM gear and Costume page. The difference is that every piece you put on the costume page will have it's stats disabled for the time you have equipped it on any costume slot.
How to use it
If the costume page is open (by clicking on the costume button) just double click the IM costume part you want to equip at your inventory and this costume part will be automatically equiped on the right slot as costume. Alternatively you can drag and drop the part your want to the slot.
If your costume page is not visible double clicking an IM costume part puts the item automatically to the IM gear slot.
_The event (reinforced) enchant insurance scrolls can now be used for enchanting without the need of having one "normal" (reinforced) enchant insurance scroll in the inventory
_The event reinforced enchant insurance scroll can now be used for soul crafting
_The event reinforced enchant insurance scroll can now be used for applying a socket card (Event versions of the scroll will automatically be used before the normal versions)
_A box with 999 Armor Enchant Dust has been added to the Vending Machine for 7 Silver Coins
_A box with 999 Weapon Enchant Dust has been added to the Vending Machine for 9 Silver Coins
Hard Caps on Movement Speed and Attack Speed
Hard caps for Movement Speed and Attack Speed will be added to the game with this maintenance.
The following caps have been implemented:
The Movement Speed Cap for all classes is at 400
The Attack Speed Caps for the classes are the following:
Human Base Classes
Party Accept Timer
The timer to accept a party has been decreased from 15 seconds to 8 seconds.
Other changes includes adjustements of Quests, adjusments of item restrictions (Market, Charge Mail, place of usage...), new Costumes, Achievement releases/fixes... (Maybe more, but I don't feel the need to mention.)
That's it from me; if you've got the nerves and need more to know, you might want to go through 5 or 6 pages of information in this section '-'
