I have tested bits and pieces regarding mining on UOF and I spread some of that information trough forum posts or chat but I want to compile it into a single place. I'll update this post over time and maybe one day convert it into a full mining guide. Feel free to give feedback or throws in your own inputs in the replies. Mining grid Ever noticed if you mine out a tile, that the tile next to it is also empty and sometimes it isn't? That's because the map is devided into a grid that consists of 4x4 tiles. All the tiles with that 4x4 range are bound together into a single resournce node. Meaning if you mine out one tile, the other tiles will also be empty. Each resource node has it's own ore color, ore amount and respawn timer. Example: Ore color: Some resource nodes have colored ore. These colors are fixed and will never change, so if you find a valorite node and come back later to mine it again, it will still give valorite. If you mine a node which has a colored ore, there is a 50% chance to get that colored ore, otherwise it will be iron ore. If you don't have sufficient mining skill, it only yield iron ore. Ore amount: TODO - On the felucca ruleset it varries between 10 and 35 ore. It appears it be a fixed amount per node, but I've seen it change a few times over the months. Not sure what triggered it. I'm guessing a server reboot, server upgrade or map update. The bountiful harvest perk doesn't appear to drain it faster, it just yields more per cycle. My guess is that I need to count cycles per node but that would imply that all results on felucca ruleset would be even (which is not the case). Clearly more testing is needed on this matter. Respawn timer: TODO - I had mixed results varying between 22 and 32 minutes. Needs more testing in regards to boundy values and exact behaviour. Melting iron - double melting chance When melting iron, there is a chance to have doubled results. I'm not sure if there is minimal mining skill required but at 100.0 skill and above the following formula applies: melted ingots = iron ore * (1 + (Mining skill / 200)) Mining gloves are taken into account! Test results can be found in reply below. Bountiful Harvest Bountiful harvest is one of many consumable perks that give your character a temporary boost. This particalur one will increase your mining yields (see Mining yields) for a limited time duration. The timer starts as soon as you activate the item in your backpack and can not be stopped (continues when outside backpack or when you log off). Once the timer runs out, it disappears. During activation, the item is blessed. These consumable perks can be obtained through: Participating in Champion Spawns (distributed like a powerscroll at the end). Loot inside a paragon metal chest. The bountiful harvest perk does not stack, so don't activate multiple of these perks at once. Mining yields Felucca facet (overland and the original dungeons): Note: It appears cave houses are no longer permitted to be mined. This will be disabled in the future. I'm to blame for that, sorry to everyone affected. 2 ore/granite per cycle. 3 ore/granite per cycle with bountiful harvest perk. Other facets (RDA's and the new dungeons): 1 ore/granite per cycle. TODO - check bountiful harvest perk. Recommended ingot prices I often get people asking for advise when it comes to selling their goods. Some people use Blaine the Gypsy's Guide: Resource/Mod Default Prices which is an excellent overall resource guide which I often consult myself. Based on my own findings, I'd say the prices aren't as linear and would recommend these price ranges instead: Iron 8-9 Dull Copper 11-14 Shadow Iron 25-35 Copper 26-30 Bronze 26-30 Gold 38-42 Agapite 40-42 Verite 53-60 Valorite 50-55 Updated January 2018 Expectations: Agapite/Valorite will slowly rise in price again. Iron will become cheaper to influx of botters and new slayer weapon deeds. Miner related changes January 2017 Weapon slayer deeds have been added to the game. Which affect the demand for colored ores since the required materials are a mix of all available colored ores. This also implies that iron will be in lesser demand. Mining no longer causes to spawn mobs, Eppy stated it missed the intend to stop afk mining. (undocumented) December 2017 (no patch notes available) Pets with less than 200 hitpoints do not suffer from skill loss, so pack horses and llama's are no longer affected by skill loss when resurrecting them. Giant beetles have exactly 200 hitpoints so they will still be affected (undocumented) November 2017 Mining spawns Earth elementals again instead of Trolls. Basicly reversing the changes from last month. October 2017 Mining spawns trolls now instead of earth elementals which is monster of the month for October. Miners are not allowed to have nice things (Undocumented). September 2017 Allow mining of crystal fragments: All Mineable crystal are now always spawning in reachable locations. May 2017 Blocked cave house mining: You are no longer able to mine inside the cave houses. April 2017 All swampy barding deeds now have the same damage reduction: Previously the damage reduction increased with ore color. Meaning valorite will be in a lesser demand now. March 2017 Mining now gives a chance to spawn mobs that drop nice stuff: Earth elementals will spawn during mining activities; see section about Earth Elementals above. February 2017 Added consumable perks and drop rate: Bountiful Harvest was introduced as a perk, which is a replacement for the old faction bonus; see section about Bountiful Harvest above. November 2016 Made granite stackable: Granite block can now be stacked. Previous each granit block was a seperate item.
