Guild raids are the main way to get more guild coins during the early game in Idle Heroes.
The guild raid consists of 60 different boss lineups, each more difficult than the last. Once a boss is defeated, you get guild coins proportional to the amount of damage you did to the boss.
In March of 2021 some Guild functionality and user-interface was revamped, but the Guild Raid functionality remains the same. You can follow this guide even with the new UI without any issues.
The new Raid functionality can be found in the Guild Altar.
How Guild Raid Bosses work
There are a total of 60 stages in the guild raid and once all stages have been defeated, the guild unlocks Flame Shrine, which is just an infinitely repeating, simplified version of the guild raid.
Each boss is more powerful, but also grants more rewards. All rewards consist of a combination of gold and guild coins.
The rewards are distributed depending on damage dealt. Alongside damage rewards, the player who deals the final blow to a boss, gets an extra reward.
Even if you didn’t attack a boss that was defeated, you still get the final kill reward, just no damage rewards.
You can attack a boss 2 times a day for free and then pay a few gems for 2 more extra attacks. If you do more than 1% damage to the current boss, you should definitely pay for the extra attacks.
Raid Boss Rewards
For simplicity, we will showcase the top damage dealer rewards, killing blow rewards and completion rewards for each boss. It is good to note that bosses 13-20 yield the same rewards and stages 21-60 give the same reward.

Is Guild Raid team building or lineup needed?
The guild raids are meant only for early- and mid-game players, which means that you should not focus your lineup with raid bosses in mind.
Only once you unlock the Flame Shrine and therefore greater rewards, should you start thinking about what lineup to use in order to inflict the most amount of damage.
As for guild raids, just use whatever your highest level and best equipped heroes are currently, as they will be doing the most amount of damage whether it be PvP or guild bosses.
PvE focused heroes like Heartwatcher or Delacium are a good idea to add in as they boost the rest of your teams damage in long matches against bosses.
If you happen to have a max level E5 hero, you will have defeated all guild bosses a long time ago with ease, so don’t worry about building a team or lineup for guild raids.
Raid Boss progress when leaving or joining Guilds
One of the most asked about, yet confusing questions about guild raids is how the progress transfers between guilds. Yes, the developers have thought of everything, so you can’t abuse the system.
When starting a new guild, the raid boss progress doesn’t carry over and always starts from stage 1 and the progress is always guild specific. This means if you beat all the bosses in a previous guild, that progress wont carry over to the new one.
However, if you already beat a certain boss previously, you will not get any rewards for defeating that boss in a new guild. This prevents farming guild coins by constantly creating new guilds and speed running the raid bosses.
It is also good to note, if you join a guild that has already defeated bosses, you will not get any rewards for the defeated bosses when you join. This means if you haven’t previously defeated some raid bosses that are defeated in your current guild, you should consider joining a fresh guild to get all possible raid rewards first.
Considering how difficult guild coins are to gain in Idle Heroes, it is recommended to take advantage of the raids and gather all the possible coins you can. However, if you have already unlocked the Flame Shrine, it’s not worth going back to any missing raids, since the shrine gives better rewards and has a cooldown after leaving a guild.
