Upgrade kits can be used on clothing to add stats to them; clothing has different slot orientation among each item. You can salvage average+ quality kits for Tools tools and Precious ore precious ore.

You cannot equip multiples of an upgrade kit with the same effect on the same clothing item, however you can spread them across different items. When you have the same update kit on multiple clothing the effect is cumulative for passive effects, and will have multiple chances of firing (even at the same time) for chance based ones.

Trading[edit | edit source]

Due to their rarity and random drop nature, it's common for players to trade kits with each other. The following are common ways to find people wanting to trade:

  • /chat dm-trade - this in-game chat room is for all trade offers, including kit trading.
  • Firetrade - A fanmade website designed around listing kits you wish to buy/sell, so people can easily find who has what they need.
  • Discord - People commonly post screenshots / google spreadsheets of what they have in the official discord's #general channel.

When trading, the quality of the kit is usually abbreviated as PQ for poor quality, NQ for normal quality, GQ for good quality, and so on with the first letter standing for the quality.

Obtaining[edit | edit source]

Upgrade kits are uncommon drops that can be found anywhere or as a drop from anything, with bosses and secret passages having a higher than normal chance to give them.

Even when a kit is found, the type of kit is random, and it's higher qualities are extremely rare.

Equipping a kit[edit | edit source]

Before you can equip a kit, you must first upgrade the clothing item you wish to equip it on with a Sewing workshop.png Sewing workshop at least once to open a slot. Once the clothing is upgraded, the first slot will open, with the other 2 slots opening as you upgrade it further.

To equip a kit, open your profile and then drag the kit onto the slot you wish it to be on. You cannot remove a kit once equipped, but you can replace it.
