* Some items cannot be improved and will reflect that when the examine command gives no information for improvement, for example: new player [[starter kit]] tools, most building materials ([[Pile of dirt|dirt]], [[plank]]s, etc), [[yoyo]]s, [[raw materials]] (which can, however, can be combined with higher [[quality]] materials to be improved (at the expense of the higher quality material)), unrepairable items, etc.
* [[Unfinished item]]s can't be improved until finished. The <tt>improve</tt> [[Key bindings|keybind]] won't work on them, use <tt>finish</tt> instead.
* The quality you can improve something up to is limited by two things:
- your skill that is used for improving
- the materials quality that is needed for improving
As example: if you have carpentry 20 and use quality 10 logs to improve a mallet you can get it to atleast quality 10, after that the logs can't be used anymore for improving this mallet as its quality is higher than the quality of the logs. You can however get up to around 30 IF you are lucky and it only wants tools for the improving processes.
Another case would be if you would use quality 40 logs with carpentry 20 to improve said mallet. You could get it without problems close to quality 30 but as soon as the quality of the item you want to improve is higher than your skill that is needed for improving the quality gain per successful improve will become less and less. Even if you keep using the quality 40 logs you will mostlikely not get the mallet over or much over quality 30 as your skill of 20 will make you unable to improve it anymore. It seems like the maximum quality you can improve to is limited by 1.5 times your skill.
The quality of your tools doesn't affect these limits but the better the quality the higher is the chance that the improving will succeed. On the other hand will higher quality tools give less skill gain for improving. So if you want to grind a skill better use quality 1 tools and things that need few material like spindles or clay shapers for carpentry, needles for blacksmithing, carving knifes for blade smithing and so on. The lighter an item is the less material it will need for improving, 5% of its weight or 0.5kg at max. This means a 60kg raft will only need 0.5kg of log and a 0.6kg spindle will need 0.03kg of log.
