looks like the success rate is directly calculated with the potential :
1 item with 13 potential on a 39 ichor (not sure where the 39 comes from) means : 13/39 -> 33% chance
a google translate says something like “Committed Item all Consumed”, maybe the translation isn’t right but it seems that the items are destroyed
Well i prefer guarantee system over RNG every day. 
Yes its weird. I got most of my Ichors done with 1 or 2 items.
Needing 3 is ‘rare’.
Someone better explain what the skills things are cause am seen Teleport in it and are not ■■■■■■■ with Teleport…
I will eat anyone that mess with my telep
Wizzard will have teleport now. Chill.
FUCK don’t you get it…
it will go from from 15 points of goodness to 5 worthless points no one will use D:
All is left is wait to see if they ruin it or keep it good…
that been said my 2 wiz having telep isn’t bad…
the waiting game has started for me D:
I can see how if they don’t have those 5 points scale like 15 points that it will make teleport annoying for escaping from people pounding your face.
idc, i have only on wiz and he is doing his job perfectly. Makes pots and scrolls. 
So the new ichor system looks like it takes the potential of 3 items and then gives you a probability of extracting the ichor out of it, at maximum potential across all 3 items it gives you a 100% chance to extract and then reduces by relative amount per lost potential.
Now if they can just tell us what materials we will need to use this service.
I’m curius how the 3 ichor will work with identified gear. Will it take a random ichor out of them or will it only work for fixed stats gear?
i want a Sheriff so hard now
Macross will save canonie
OMG, im a Matross main now!
Cannoneer + Matross <3
Am I the only who thinks tiger hunter is really cool?
Sheriff looks nice, but I can’t be an evil pirate and law enforcing sheriff at the same time. It feels so wrong!
…okay, maybe I can, if the skills are great.
The way they’re previewing the classes, sounds like they’re coming on March. All the 4.
Could it be?
IT BEGINS
Our Savior Crevox is here. 
Give us something good.
Episode 11: New Item System and Classes (Part 1)
Hello, this is the Tree of Savior development team.
With the last post, saviors submitted many questions and showed both great interest and concern in the new item system. In order to resolve some of these concerns, we will be disclosing some specifics about the new item system ahead of time. In addition, we will introduce some new changes to the base classes, and four new classes.
New Items: Unique and Legend Grade
New unique and legend items will appear with the update to level 420. These items will require level 400 to equip.
New System: Set Bonuses and Ichor
Any new set bonuses added to new equipment can be directly chosen by you.
Also, a new flexible system is being added to ichoring to give you a 100% chance of making the ichor. Adding equipment (up to 3) will boost the success chance up to a maximum of 100%, each based on their current potential (33% each if they are all at maximum potential). Three different items may be used, however, the one that has the ichor created will selected randomly.
As you can see in the picture, because the potential of each equipment is at maximum, they all add up to a total of 39, with 13 potential each. With 13/39 maximum potential, the success chance boost is 33% each.
Upon success, you will gain the ichor of one of the three items. They will all be consumed.
Extract the Ichor
Also being added is a new system that will let you extract an ichor that has already been equipped to a legend item. This requires a certain amount of silver, and there is no randomness involved. This system is planned to be added alongside updates with new legend raids and equipment.
With the new update, the number of times you can enter legend raids will change to 5 per team. With this, the quantity of rewards and their contents will be adjusted. Also, in stage 6 and 7 of challenge mode, you will be able to obtain a new recipe to craft Legend Raid Portal Stones. You need the regular, existing version of Raid Portal Stones to craft these.
With Legend Raid Portal Stones, you will be able to enter existing legend raids even if your team has consumed all of their entries (Earth Tower, Velcoffer’s Nest). These stones will not be immediately available for new content, and will be used when necessary to increase the speed/supply of the amount of rewards that come from content.
Special changes are being made to each base class with the new update. These changes aim to make alterations to the basic ability of classes to evade and defend themselves.
Pain Barrier
Pain Barrier will apply an additional buff that provides 100% immunity to debuffs. However, this buff is separate and different than the knockdown/knockback immunity, so it will have a different duration.
Teleportation
Psychokino’s Teleportation will be changed to a Wizard skill.
Leap
Mergen’s Jump Shot is now an Archer skill, the attacking portion of it is removed, and it will reduce your threat on use.
Cure
Cure will be able to remove higher ranked debuffs.
Cloaking
Cloaking will be changed to only be usable out of combat, but it will increase your movement speed further.
Anything is subject to change when the updates arrive.
I’m confused by the ichor change. Does that mean that if you use one 13 pot item you will get 1 go at 33% chance of ichoring compared to the 14 tries at 5% chance you have now? This of course removes the randomness if you have 3 items, but for 1 item that lowers the chance by a lot. Depends on the requirements of course: having to put one batch of Sierra or one Extraction Kit instead of 14 would probably make the process worthwhile…
