To start, I should clarify the definition of procedural loot. The term Procedural loot describes items that are named as 'Magical <x>'. The properties present on these items are randomly generated when they are created. These items are spawned on mobs, bosses, and chests, though they do not infringe on loot created by the traditional loot system. It is possible for more than one item to spawn at once.
These procedural items have a chance to be tailored. In this context, a tailored item is an item whose properties have been generated to complement a specific character. The tailoring algorithm works as follows:
- If a skill, it will only include skills that you have invested points into, plus heal and discipline.
- If a stat, it will use your two highest stats plus CON, excluding INT if you don't have a level in wizard or assassin.
Drop rates in a party are not accelerated, but they draw from a broader range of characters (the ones in your party), which means that when soloing you might have a 50% chance for an item to drop, and then a 25% when that one drops, whereas in a party, you will have four 50% chances, then four 25% chances. Overall, you will gain more loot, and the loot will be tailored for each party member in turn. Note that loot from mobs will never be tailored; only loot from bosses or chests will be.
Loot scales based on the level of the mob, boss, or chest. The character level does not matter. Low level loot will generally contain fewer properties and have more weaker skill rolls than high level loot.
I am going to refrain from provided exact spawn rates and lockout periods to avoid abuse of the system, but I will explain the two types of gear that can currently drop.
- Tier 1 gear described basic adventuring gear. This gear can spawn with 1-4 properties, and one of those properties can be an increased stat. The rest of the properties will be skills. Boots can spawn with +1 AC.
- Tier 2 gear describes advanced adventuring gear. This gear can spawn with 3-6 properties, and two of those properties can be an increased stat. The rest of the properties will be skills. Boots can spawn with +1 AC.
In summary:
- The loot system rewards occasional adventuring by providing high percentage drop chance gear which is tailored to be useful to at least one character in your party.
- The loot system facilitates grinding by allowing loot to continue to spawn after all tailored item slots have been acquired for the period. However, further items spawned during this time are not tailored, meaning the loot generation system can pull from any stats and any skills.
- Make sure to invest a skill point in any skills you wish tailored gear to include.
Procedural items now have a chance to spawn with the runic property. The runic property improves the success of next property to be enchanted on an item based on the following rules:
- Skill Focus: Enchantment: +33% success rate.
- Greater Skill Focus: Enchantment: +66% success rate.
- Epic Skill Focus: Enchantment: +100% success rate.
