Guild Renown

Overview
Guild Renown is the method that a Guild uses to gain Guild Levels, as a Guild goes up in levels they unlock various Guild rewards. See Guild Level article for the list of rewards.

How to get Guild Renown
The most basic way to gain renown is to kill NPC's, once an NPC has been killed whether by you or another party member (and you must be inside the quest instance) you will have a percentage chance of gaining renown from that kill.

Guild Trophies (Renown tokens) can also be found in chests and reward lists sometimes.
 * Heroic Deeds - + 50 Guild Renown
 * Tales of Valor - + 150 Guild Renown
 * Impressive Trophy - + 500 Guild Renown
 * Legendary Victory - + 1,000 Guild Renown


 * "We've made a change where mob renown won't rely on collectible bags. Hopefully this change will hit Lamannia on Friday." (Dev MadFloyd on 06-10-2010, 08:30 AM link)
 * "'Odds of renown dropping should be similar to the mechanic used to give XP vs the level of a quest. The higher the player is vs the content the lower the odds, and vice versa.' That has always been the intention." (Dev MadFloyd on 06-10-2010, 01:02 PM link)
 * "We've increased the base chance of finding trophies in chests, and also increased the "epic difficulty" bonus. End rewards should have trophies available very often. (Nearly 100% for Long or Very Long dungeons, in fact.)" (Dev Eladrin on 06-10-2010, 10:38 AM link)
 * "When you run quests at level, you have a 20% chance of finding renown in chests. For every level you're above the quest level, that chance is reduced by 4%. So if you're 3 levels over, you're looking at an 8% chance to find renown." (Dev MadFloyd on 07-22-2010, 01:01 PM link)
 * "the length of the quest affects your chances for renown in the end reward. Unless you're 5 levels over the quest, you should have a minimum of 50% chance to see renown and it goes up from there to 100% for a very long quest." (Dev MadFloyd on 07-22-2010, 01:43 PM link)
 * "it's based on the player with the highest level in the party." (Dev MadFloyd on 07-22-2010, 03:08 PM link)
 * "On Epic you have a 7% additional chance for drops from chests and monsters compared to Normal." (Dev MadFloyd on 07-22-2010, 03:09 PM link)
 * "the level of the quest iplays [sic] a role in the average value of the renown." (Dev MadFloyd on 07-22-2010, 03:30 PM link)
 * "Guild renown drops from chests and end rewards have been increased. End rewards now have a 50% chance to drop." (Update 5.1 Patch 1 release notes on 07-26-2010, 11:59 AM link)

Small Guild Renown boost
Small guilds (by number of unique accounts, not characters), get a "small guild bonus" to renown received by any of their members. 25 accounts or less should get this bonus. The bonus is supposed to ramp up the lower number of accounts are in your guild (26+ accounts get no bonus, 25 accounts get a small bonus, 24 accounts gets a slightly larger bonus, etc.).

Example: If you had 6 unique accounts in your guild your small guild bonus would be 300% of the base renown gained. A Heroic Deeds (50 renown) would be 50 + (50 x 300% = 150) = 200 total.

How Guilds Lose Renown
When guilds started getting to level 26, many noticed that they experienced a large amount of decay instantly on hitting the level, dropping them back down to level 25. Subsequent decay occurred exactly 24 hours later after that initial hit and was a lot smaller. For Over Raided, that initial hit was either 944 or 964 (no one really bothered to record the renown right before hitting 26 since no one was expecting the decay, so this is guesswork), whereas on the subsequent day, also at level 26, the decay was only 152. Afterward, the developers acknowledged that this initial large decay was a bug and that they toned down the decay until a patch could be applied. A patch subsequently came on July 21, and presumably, the decay amount has been adjusted back to their original intended amount -- decay based on data gathered before July 21 is exactly half of what the post-July 21 data gives. Since the patch, the decay has occurred at a fairly predictable interval. Thus, the following is based on data collected since July 21, the day of the patch.

 Determining your guild's renown decay Next, about how to figure out what the decay actually is for your guild. The decay occurs once each day, every 24 hours. The time of day that it occurs is pretty consistent, although it seems to be slowly drifting later with each day. It seems to be calculated in real-time, i.e. it looks at the guild level and the number of accounts in the guild at the time the decay occurs. I provide this for informational purposes only (so that people can figure out what their guild renown decay is). I would fully expect Turbine to punish any guild that uses this timing to deliberately reduce their daily renown decay as an exploit. You are warned.

For a guild that has over 25 accounts, assuming no one in the guild is using renown pots, the time of the decay should be fairly easy to determine. Simply look at the renown throughout the day and look for when the renown did not increase in a multiple of 5, since all the renown gained should be in multiples of 5. So for example, if your guild's renown was 4759438 at some time, then you should look when the last digit (units digit) is no longer 3 or 8 but changes to something else like 1 or 6. The decay will have occurred between when you last observed it at the original values (i.e. 3 or 8) and when you first observed the new values (i.e. 1 or 6). For a guild with 25 accounts or less, using this method is more difficult because in general there will be rounding issues with the small guild renown bonus when you get 5 renown from a monster kill. However, if your guild has 22 accounts (60% bonus), the renown gain is in multiples of 8, if your guild has 18 accounts (120% bonus), the renown gain is in multiples of 11, and so forth. Basically, if your bonus is a multiple of 20%, this method can still work, with a suitable multiplier. Otherwise, you'll just have to be hope to get lucky I guess and see when the renown decreases.

Using this method, you can gradually narrow down the window of time that the decay occurs for your guild until you determine it precisely. However, for most guilds, there's an even easier method: try looking at the same time as when the servers were last brought up from maintenance or otherwise being down. Currently, this is around 12:00 pm PST due to the 9-hour maintenance on Monday, 8/16/2010. For guilds that just hit level 26 recently, look for the decay to be every 24 hours after you first hit 26, although I suspect that whenever there's a patch or something, the time may get moved to the "standard" time of when the servers were brought up.

One way to look at decay rates for guilds as a whole is to just spam update the guild leaderboards during this time. This is indeed a useful approximation. However, the webpage only updates in intervals (i.e. it's not getting the real-time game information about the decay, but updates each guild's renown every say 5-10 minutes or so). Since each guild is presumably still gaining renown during this period, the decay observed is useful only to get a lower limit on how much the actual decay was, i.e. the actual decay will be more than or equal to the observed decay, since the guild was probably gaining some renown during the interval which partially offset the decay.

The most accurate way however once you know when decay hits for your guild, is to just spam "O" (the guild panel), continually recording the renown when it changes, and record the last value right before the decay and the first value right after the decay. Hopefully, you can also ask your guildies to let you know if they got any renown during that time (so that you can see if you saw it before the last value before decay or after the first value after decay, or if it got jumbled into the decay) -- I generally tell guildies around 2 minutes before I think it'll hit to let me know if they get any renown within the next 5 minutes.

Guild renown decay formula
The formula for renown decay is a level-based multiplier times an account-based multiplier. It does not depend on your current renown (although your current renown of course determines your current level). What this means is that a level 31.9 guild will incur the same amount of decay as a level 31.1 guild, assuming the same number of accounts.

The account-based multiplier is the number of accounts + 10. This means that a 15-account guild will have a decay as if it were a 25-account guild, while a 700-account guild will have a decay as if it were a 710-account guild. This was tested only in the range of 15-22 accounts, but applying it to the big guilds based on their decay gives reasonable estimates of their account. That is to say, when I apply it to (for example) a 700 character guild (based on the leaderboard), I get a decay for (for example) around 500 accounts, not 100 nor 1000 accounts. So it seems like this should apply through the entire range of accounts, until there is further data on this. The way to test this is simple -- after I got data on the decay at a certain level, if the guild didn't level up before the next day, I added a few junk accounts to artificially increase the guild's size, and (since the level stayed the same) can figure out how much those extra accounts contributed to the decay. The extra accounts decreasing the guild's small guild renown bonus when we didn't level also served as a punishment for guildies slacking off from the one-level-per-day pace.

The level-based multiplier is as follows. Take the minimum renown needed to be at that level (not the current renown of the guild), which is actually just 50 * Level^3 (kudos to Grendyll here). Take every 5 levels starting at the onset of renown decay to be a tier (so level 26-30 = tier 1, level 31-35 = tier 2, etc.). Multiply the renown by the tier that the level is in. Then, multiply the product by the following:


 * Level 26-40: 2.5
 * Level 41-60: 3.0
 * Level 61-80: 3.5
 * Level 81-100: 4.0

Now divide by 1000000 (1 million). The result will be the level-based multiplier for renown decay.

If the above sounded too confusing, below is the level-based multiplier by level:
