There are multiple ways to improve your equipment. There are item upgrades which can increase rarity and upgrade bonus. Gems that can be attached to weapons to increase attack speed, critical hit and life leech. Items can also have a variety of stats, from more hp to additional gold gained from loot.

An item can have four levels of rarity. Common, Rare, Epic and Legendary. Each rarity increases the attributes of the item, the item level and the number of stats possible. Common has one, Rare two, Epic three and legendary has four slots for stats.

Rarity will give your item increased attack, defense or armor depending on the item type (melee and distance weapons / shields / rest of equipment)

For example, having these items as base:

Below, we have a table that explains it.

Rarity of the item will also increase the item level. Every rarity will double the base item level and increase it with 5 for Rare, 10 for Epic and 15 for Legendary.

Upgrading the rarity of an item requires a Rarity Upgrade Crystal. These are primarily crafted but can also be gained from a few quests.

Upgrading rarity is not guaranteed and there is a chance to fail for each attempt. Each failed attempt will increase the chance of a successful upgrade slightly, depending on the current rarity. The most difficult upgrade is from Epic to Legendary.

You can also loot ‘unidentified’ items and they will require a scroll of identification to see its true stats and for being able to use that item.

Scrolls of identification can be purchased from Eremo for 5k gold, or looted from demonic/diabolic monsters. Unidentified can be any rarity and upgrade, depending on your luck!!

Each item slot (not backpack or quiver) has its own set of upgrades it can have. For example, a wand has a rare chance of getting an upgrade for magic level, where melee weapons and distance weapons cannot.

You will get higher bonus when getting more item level of your gear, it works like this:

Some parts of the upgrade system are dependant on each other, one such example is upgrading the items,

Each upgrade level will raise the item's base stats and item level. Item level determines the strength of the attributes on the item. So higher item level = stronger attributes (but you will have to reroll the values after upgrading.)

For each level on your gear you will have:

There are five different gems that can be applied to weapons.

The difficulty to apply a gem increases with each attached gem.

Existing Crystals

Name	Description
Crystal Fossil	Can be looted as a rare item from bosses, is obtainable as a reward from quests and you can trade 1 for 5 skull coins in skull shop in Darashia.
Crystal Extractor	Looted from demonic / diabolic monster and bosses. They are also needed for crafting gems.
Rarity Upgrade Crystal	Increases rarity of items from Common → Rare → Epic → Legendary.
Upgrade Crystal	Used to raise items to +1, +2, +3,…
Enchantment Crystals	Using this crystal on an item with an empty slot, will add a random attribute.
Alteration Crystals	Removes the last attribute on an item.
Cleansing Crystals	Used to remove ALL attributes from an item. (tip) If you are re-rolling the first attribute on an item, it is better to use these crystals because they are far more common than alteration crystals. It may also be beneficial to hold onto some of these crystals while exploring edron.
Fortune Crystals	Used to change the value of the last attribute on an item.
Faith Crystal	Used to change the value of ALL attributes on an item. (tip) Similar to the cleansing crystal, these can be used if you only have one attribute on an item and are running low on fortune crystals.
Exchange Crystal	Rotates all attributes on an item. Attribute one will move down to second, second to third etc and the fourth attribute will become the first.

Equipment crystals for item modification can be crafted at the anvil in Leo's Enclave (downstairs)

Every crystal or gem requires 10 crystal fossils along with two certain components, such as different kinds of quartz which can be obtained via the mining skill or ingots crafted from ores, creature products and a cost fee for crafting. A list of craftable gems and their recipe will be displayed below. Craftable crystals:

With these crystal an item's stats and attributes can be enhanced, removed or changed.

With these gems, which are also obtainable from gem boxes, enhance weapons with specific enchantments.

Upgrade items you plan to keep for long periods of time. Not the first halberd, crossbow, or plate armor you may find.

First thing you do when you have the proper item is to upgrade it with upgrade crystals.

The higher the item level, the higher the rolls on the attributes.

Once the item is upgraded, you will need enchantment crystals.

One at a time, see if it is an attribute you like.

If not, cleansing crystal (or alteration, but cleansings are more common) to erase the attribute and try another enchantment crystal.

When you get the attribute you desire, you may want to roll for a higher value.

Faith or fortune crystals can be used here for the first attribute (only the first attribute, 2nd, 3rd and 4th you need to only use fortune)

When you have landed on the value of the first attribute you want to keep, time to add another enchantment crystal.

Because you do not want to mess up the previous attributes, do NOT use faith or cleansing crystals anymore.

Now you can rinse and repeat until you get the perfect item with the perfect stats.
