Aion 2 Gear Stat Reroll Guide: Which Piece to Keep and the Cheap +15

Keep the rarer line

Say two weapons dropped, one with Combat Speed and one with Damage Boost. In the short term, Combat Speed is the much better line. But you'll want both in the end. Whichever weapon you keep, the other line is still missing, and you Sync until it rolls. The rarer the missing line, the more Syncs it takes:

So keep the Damage Boost weapon: 25 Syncs against 50. You'll want Weapon Damage Boost too, but it takes about 25 Syncs on either weapon, so it doesn't change the choice.

It works the same on every piece. Take gloves as another example: say two dropped, one with Combat Speed and one with Perfect Chance. In the short term, Combat Speed is much better for damage and Combat Power (CP), but you'll want both lines in the end:

So keep the Perfect Chance gloves: 36 Syncs against 90.

Each Sync uses up a spare Unique piece, about 1.5 million Kina each, so keeping the rarer line saves:

The same rule on the other slots, for the lines the best stats guide chases. The percentages are each line's chance to roll on a Sync or Reset, as the game's Soul Binding window shows it, not its value:

On the helmet, cape and pants both chase lines have a 0.96% chance to roll, so keep the better one: Double Chance on the helmet and cape, Attack increase on the pants. On the necklace, Combat Speed, Might and Precision all have a 1.6% chance to roll, so keep the better one there too.

The Syncs to land a line depend only on its chance to roll. On average, onto a piece with none of it yet:

The level 36 route

Item-level-36 to 41 Unique gear, such as Fantasy (36), Spectral and Courage (41), rolls the same lines as item-level-86 gear, such as Nuakum and Enraged Kromede, at the same chances. Every fresh piece is a new roll: its four lines appear on its first Soul Binding, for one Bind (30,000 Kina and 10 Soul Codex). Save your Soul Binding Resets for accessories: Courage has item-level-41 accessories, but they're mostly absent from the Market, so there's no cheap low-level route for them.

1. Buy item-level-36 to 41 pieces of the slot you want on the Market, at roughly a million Kina a piece, or farm them in the fields and the Abyss (where each drops).
2. Soul Bind each once to see its lines, and keep the one with the rarest chase line.
3. Sync more lines on only if it already has one or two chase lines and you want more, using the spares as material: any Unique piece works, from any slot.
4. Enhance it to +15 (costs below).
5. Transfer it onto a fresh item-level-86 piece of the same slot, such as Nuakum or Enraged Kromede: +0 and never Transferred onto. A weapon only Transfers onto the same weapon type, a greatsword onto a greatsword. It takes 1 Transfer Stone onto crafted gear and 2 onto Abyssal, Enraged Kromede and Nuakum gear; make them from your leftover spares in Substance Morph. The enhance level and Soul Binding lines move; the Gear Transfer guide has the rules.
6. Soul Fuse it only if you'll keep it a while, such as a piece you won't replace soon: Soul Fuse doesn't transfer, so it's lost when you move the lines on.

What +15 costs

Enhancing has the same chances at item level 36, 41 and 86, and a failure keeps your level and adds 5% to the next tap. Average Kina per level, failures included:

And the Enhance Stones:

From +10, it averages about 12 taps. At item level 41 (Spectral, Courage), +0 to +15 averages 6.0 million Kina and 76,667 Enhance Stones. The saving per piece is about 7.3 million Kina and 93,000 Enhance Stones, less the item-level-36 piece and its Transfer Stones. Put the spare Enhance Stones into Amplify Stones in Substance Morph: each takes 2,500 of them and 4 Amplify Stone Fragments (Unique), as in the gear score guide. Bind and Reset cost the same at both item levels.

FAQ

Should I keep a weapon with Combat Speed or Damage Boost? Damage Boost, even though Combat Speed is the better line for now. You'll want Combat Speed and Weapon Damage Boost on it too, and Damage Boost is half as likely to roll, so it saves about 25 Syncs: about 37.5 million Kina at 1.5 million a spare Unique piece.

Is Reset cheaper on item-level-36 gear? No. A Reset costs 300,000 Kina and 3 Soul Codex: Reset at both item levels. Save Resets for accessories, which have no cheap low-level route; on other gear, roll fresh pieces and Sync.

Is a Sync Stone better than a spare Unique piece? No: either gives 100% on Unique gear, from any slot. Use spare pieces first.

Should I enhance or roll the lines first? Roll first: pick the piece by its lines and Sync the rest onto it, then enhance it and Transfer it.

How much does +15 cost in Aion 2? About 12.6 million Kina and 160,752 Enhance Stones on item-level-86 Unique gear, or 5.3 million and 67,328 on item-level-36 gear you then Transfer, on average.

Do Soul Binding lines move with Gear Transfer? Yes, with the enhance level. The Soul Fuse line and the stones in the sockets don't.

Can I choose which lines survive a Transfer onto a three-line weapon? No. A piece with fewer lines keeps that many at random, so an Enraged Kromede weapon takes three of an item-level-36 weapon's four. Transfer onto an Abyssal or crafted weapon to keep all four.

Transfer's rules: the Gear Transfer guide. An item-level-36 piece's Market price, and a spare Unique piece's 1.5 million (it varies by server), are from our own play. Our calls, judged on the chances and the cost tables: keeping the rarer line, since you'll want all of a slot's chase lines in the end; Syncing on item-level-36 gear only once a piece has one or two chase lines; and saving Resets for accessories.
