Item Workbench
Item Workbench on Sarim, an OSRS private server.
Sarim utilizes an Item Workbench that allows you to apply perks to gear to provide additional purposes and bonuses. The Item Workbench can be found east of the home area.
Obtaining Materials For Upgrades
In order to add perks to your gear you'll first need to break down items and gear for materials. In order to do this, right click the Item Workbench and select Item-breaking. This will open a window for you allowing you to select a specific item to break, all available breakable items in your inventory, and view/deposit/withdraw your materials.

Item Upgrades
There are plenty of upgrades to apply to your gear once you have enough available materials to do so.
When first attaching an upgrade to your gear, it will apply it at Tier 1. You'll then have the option to attempt an upgrade to obtain a higher tier, rolling it between tiers 2 and 5. The level of the upgrade determines how much of a boost the upgrade will give you.
It's important to note that when attempting an upgrade for a higher tier of a perk, you CANNOT roll a level lower than what you already have.
