Upgrade Guide: +9, Scrolls, Bonuses, Stones and Biologist

Gear is upgraded from +0 to +9 at the village Blacksmith; every step costs Yang and has a success chance, and after +6 it also needs monster materials. If a normal upgrade fails the item is destroyed; a Blessing Scroll drops it one step instead, while Magic Metal and Ritual Stone keep it. After +9 comes the transformation; bonuses, stones, skill books and biologist quests make your character stronger on top of that.

Step by step

Prepare the item and materials
Open the item's wiki page, check the Yang, chance and material of each step and collect the materials.
Upgrade +0 → +4 normally
Talk to the Blacksmith and choose the item; the first steps are cheap and likely to succeed.
Use scrolls from +5
Drag a Blessing Scroll or Magic Metal onto the item; the item is not lost if it fails.
Transform at +9
Collect the transformation materials and turn the item into the +0 of the next item at the Blacksmith.
Add bonuses
Use Reinforce Item up to 4 bonuses, Blessing Marble for the 5th, and Enchant Item to reroll.

1. Blacksmith +0 → +9

Drop the item on the Blacksmith or talk to him and choose upgrade. The window shows the Yang, the material and the success chance. Every item has its own table on its wiki page. Example: Sword+0 (the first sword of warrior and sura):

Step	Chance	Yang	Material
+0 → +1	%90	50k	—
+1 → +2	%90	100k	—
+2 → +3	%90	250k	—
+3 → +4	%90	500k	—
+4 → +5	%81	1m	—
+5 → +6	%63	2m	—
+6 → +7	%54	3m	Bear Foot Skin ×1
+7 → +8	%45	4m	White Hairband+ ×2
+8 → +9	%36	5m	Broken Porcelain ×2

Higher items have lower chances and higher costs; from +5 they ask for pearls, crystals and boss parts. Most materials are sold by the Upgrade Material dealer in the village; the rest drop from monsters and Metin stones.

If a normal upgrade fails, the item is destroyed (with its bonuses). Upgrade valuable items with the scrolls below.

2. Upgrade scrolls

Drag the scroll onto the item; the same recipe applies (Yang and materials are still used), only the result of a failure changes.

Scroll	Chance	If it fails	Where from
Blessing Scroll	as in the recipe	item drops 1 step	General Store (2m), chests
Magic Stone	as in the recipe	item stays, no step lost	bosses and Metin stones
Sapphire Blessing Scroll	recipe +10% (items below Lv90)	item drops 1 step	Item Mall 5 EP, chests
Golden Blessing Scroll+	recipe +10% (items Lv90 and up)	item drops 1 step	Item Mall 8 EP; Blacksmith recipe: 50 Blessing Scrolls + 80 Zen Beans + 50m
Ritual Stone	recipe +10% (items Lv80 and up)	item stays, no step lost	Item Mall 25 EP; Blacksmith recipe: 3 Magic Metal + 400 Zen Beans + 100 Cor Draconis Chests + 500m

For the cheap steps (+0 → +4) a normal upgrade is enough. From +5 use a Blessing Scroll, and for expensive high-level items Magic Metal or a Ritual Stone.

3. After +9: transformation

A +9 item transforms at the Blacksmith into the +0 of the next item. Most transformation steps succeed 100% of the time (the Evolution steps 55-80%), but they need a lot of Yang and special materials (e.g. Battle Sword+9 → Triton Sword+0: 300m + Dragon Scales ×3 + Dragon Claw ×3 and two more materials).

Line A starts with Lv65 weapons: Battle Sword+0 → Triton Sword+0 → Rune Sword +0 → Kyanite Sword+0 → Evolution 1-5.
Line B starts with Lv75 weapons, which only drop: Poison Sword+0 → Legendary Poison Sword+0 → Zodiac Sword+0 → Gloom Dragon Sword+0.
Armour: Black Steel Armour+0 → Blue Steel Armour +0 → Devil's Horn Armour+0 → Aurora Armour+0 → Magma Glow Armour+0 → Kyanite Armour+0.
Evolution (after Kyanite +9) needs Scroll of Evolution; the chance goes from 80% down to 55%, but on failure the weapon is kept; only materials and Yang are lost.

All chains are drawn on the Evolution trees page.

4. Bonuses

Reinforce Item: adds 1 bonus to an item, up to 4 bonuses. 1.25m at the General Store.
Blessing Marble: adds the 5th bonus. 5m at the General Store.
Enchant Item: rerolls the existing bonuses. 1.2m at the General Store.
6th and 7th bonus: 6/7 Reinforce Item adds them, 6/7 Enchant Item rerolls them. They drop from Metin stones above Lv100 and from big bosses; also in the Item Mall (200 / 150 EP).
Separate enchant/reinforce items for gloves, talismans, belts, costumes and wings: Seon-Hae in the village makes them from Enchant Item (30 or 50 pieces + Yang); belt, costume and wing items are also in the Item Mall.

5. Stones

Stones for weapon and armour sockets drop from Metin stones; most Metin stones drop one stone of a random type every time they break.
The General Store sells +4 stones (50m); stone upgrade recipes are at the Blacksmith.
Metin, Monster and Boss power stones are the most effective stones for PvM.

6. Skill books and Soul Stones

Skills reach M1 with points; M1 → G1 with skill books, G1 → P with Soul Stone. Each reading can fail and there is a waiting time between readings.
Exorcism Scroll skips the waiting time, Concentrated Reading makes the reading succeed; both cost 1m at the General Store.
Skill Book Chest drops from Metin stones and bosses. The Book Seller in the village turns spare book chests into passive skill books (Monster Hunter, Metin Hunter, Berserker and more).

7. Biologist quests

From level 30 Biologist Chaegirab in the village gives quests. You hand in the requested item one by one; each hand-in is accepted with a 50% chance and there is a waiting time between them. Then you hand in the quest soul stone (sold in the Biologist's shop). Rewards are permanent. Biolog Time Watch resets the waiting time, Biolog Chance Elixir raises the acceptance chance.

8. Alchemy, sashes, mounts

Dragon Stone Alchemy: open the alchemy window with the green gem button in the inventory; opening a Cor Draconis Chest gives dragon stones.
Sashes and aura: Teovahdan in the village gives simple shoulder sashes and the aura outfit for Fine Cloth.
Mounts and pets: the Stable Boy turns permanent mount and pet seals into stronger ones (needs Zen Beans, Cor Draconis Chests, Crafting Symbol and Yang).
