Every piece of gear carries several upgrade systems at once. Some survive a transfer to a better item and some don't, which decides where your materials should go.
What every item carries
| Layer | What it adds | Kept when you transfer? |
|---|---|---|
| Enhancement and Amp | + levels, then Amp levels with extra orange stats | Converted: Unique +15 Amp 5 becomes Heroic +20 Amp 0 |
| Stat lines | Random lines, rerollable, strengthened by soul binding | Yes, except the Philosopher's Stone line |
| Mana stones and soul stones | Random extra stats | No |
| Theostone | A small proc effect on weapons | No |
| Potential | PvP damage boost or tolerance on dungeon and crafted gear | No |
Enhancement and Amp levels
- Unique (yellow) gear enhances to +15 and Heroic (orange) gear to +20, using Kina and Enhance Stones.
- Both then take five Amp levels with Amplify Stones, each adding orange stats. At max Amp a weapon gains 150 Attack and 5% attack increase; accessories gain 100 Attack, 200 defense and 5% attack increase. Those are Asia's figures and global's aren't confirmed.
- Success rates drop to around 60% at +16.
- Weapon and guard first. They carry your highest offensive stats and share the same stat lines.
Stat lines worth chasing
Each item rolls lines from its slot's pool. Reroll one line with a Synch Stone of the same grade. A lower-grade stone has only a 10% chance to change anything. Soul Codex: Reset books shuffle every line at once.
When you land a good set, move it to better gear with a transfer rather than fishing again.
| Slot | Lines to chase |
|---|---|
| Weapon and guard | Damage boost, combat speed, weapon damage boost, Might |
| Helmet | Double ChanceKorea calls this Smite, attack increase |
| Cloak | Double Chance, attack increase, Perfect Chance |
| Shoulders | Critical damage boost |
| Chest | Damage boost |
| Pants | Attack increase, perfect |
| Gloves | Perfect, combat speed |
| Boots | Perfect, movement speed |
| Necklace and earrings | Attack, then passive skills |
| Rings | Attack, then active skills |
| Bracelet | Pantheon stats — Illusion, Wisdom, Destruction and Time first |
Fill every remaining line with Attack or skill levels. Rings are the only accessory with active skill lines, which makes them key to getting skills to level 20.
Mana stones and soul stones
Mana stones go in weapons and armor, soul stones in accessories. Each stone rerolls every socket on the item.
- Aim for at least one yellow damage boost line. It's worth a full 1% of that stat, more than three blue rolls.
- Best to worst: front/back damage boost, then weapon or critical damage boost, then damage boost, then attack. Two yellow attack lines are roughly one yellow damage boost line.
- Don't spend superior stones on gear you'll replace. Stones are lost on transfer.
Soul binding and transfers
Soul binding raises the value of each stat line with Soul Codex books; every book is a guaranteed gain of a random size. Once every line reaches 100%, two Philosopher's Stones unlock an extra line. That line is lost on transfer, so try not to land a rare roll there.
Transfers move enhancement and stat lines onto a new item, using Transfer Stones built from fragments. One broken-down Heroic item gives five fragments:
| Transfer stone | Fragments | Heroic items to break down |
|---|---|---|
| Accessory | 10 | 2 |
| Armor | 15 | 3 |
| Weapon | 20 | 4 |
Moving Unique gear up to Heroic needs five extra Unique transfer stones on top.
Pet Genus
Five boards with nine stat lines each. Raising a board's Insight level opens more lines and better grades, and analysing rerolls every open line.
- Level each board to 9 before locking anything. Locking early caps the grade you can reach.
- Roll the Special Board's slot 4 until it shows Double Chance. That slot has no second-best stat, and it's the only one on the boards that carries it.
- Fill the rest: boss attack or crit on lines 1, 4 and 7; max attack or attack bonus on 2, 5 and 8; damage tolerance on 6.
You can save three Genus presets. Full detail in the Pet Genus guide.
Wings
Wings give stats when equipped, and extra stats just for owning them, so a large collection pays off even for pairs you never wear.
Enhancing a pair to +10 grows its owned effect, and that's switched off at global launch. The client carries the ceiling, on 25 of the 45 pairs, but there's nothing you can spend on it yet.
So a pair's hidden line stays hidden. Brawler Wings only pay out their weapon damage boost once enhanced, which puts that line out of reach for now, and collecting pairs is the only wing progress open to you.
Front-attack classes mostly wear Eroded Wings. Talisra Wings, with cooldown reduction, are the common alternative, and nearly every Sorcerer uses them.
Arcana
Arcana cards each carry a Pantheon stat plus up to four stat or skill lines, and matching cards form set bonuses. Global launches with five card types and two sets, Primal Vigor and Magic Armor.
- Early on, Pantheon stats beat set bonuses. Look for Time for combat speed, Destruction for attack increase, and Wisdom for Double Chance. The client prints each with its deity, so on a bracelet they read Time [Siel], Destruction [Zikel] and Wisdom [Lumiel].
- Use cheaper cards to push key skills to level 20 first, then work toward crafted cards.
- Crafting lets you choose your lines. The Chalice has the widest pool and is hardest to roll well, so craft it first.
- Level cards to 5 by feeding them other cards or Training Arcana. Feeding an old card into a new one keeps some of its experience.
Where to spend first
- Enhance your weapon and guard.
- Push your key active skills to 20 with rings, Arcana and Daevanion tiles. Which skills, and why 20: more damage at the same Combat Power.
- Level every Pet Genus board to 9, then roll each board's slot 4.
- Reach the accuracy and crit targets for your content.
- Save superior mana stones for gear you'll keep.
- Grow your wing collection and closet over time. Both are slow, permanent stats.
