Coliseum Enemy Experience
What is this guide?
In this guide, I explain the conditions under which dragons are awarded experience by defeating Coliseum enemies. The second post contains links to the amount of experience that you will gain for defeating certain enemies under particular conditions.
Experience mechanics
Every enemy gives a base amount of experience. This can be modified by your dragons' level advantage over the enemies (which, if significant enough, can give you reduced experience) or the bonus experience multipliers (which will give you increased experience).
- The level advantage penalty multiplier is applied first to each enemy individually.
- Each individual enemy's experience contribution (after level advantage penalty multiplier) is added up into a single sum.
- Bonus experience multipliers (including the victory chain and event experience boosts) are applied to the total experience amount after each individual enemy's experience contribution has been summed together. Bonus XP multipliers stack multiplicatively with each other.
Level advantage penalty multiplier
If your dragons have a significant level advantage over the enemies, you may get reduced experience. The level advantage is calculated by comparing each specific enemy's level to the highest level in your party; the zone's specified level does not affect this experience penalty. Some enemies are much lower level than the zone because they debuted in an earlier zone, some are high enough level that you won't get a penalty from them while tackling multiple zones in the level-appropriate range, and so on.
Experience deteriorates by 25% per level, starting at 3 dragon levels above the enemy's level. If you've got a 25% level penalty, you multiply the experience by (1 - .25), which is .75. If you have no penalty, the multiplier is simply 1.
To find the total experience after applying the penalty, use floor (penalty multiplier * individual base enemy exp). To take the floor of a number, you simply round down to the nearest whole number. For example, floor(8.9999) = 8, not 9.
If your dragons are fighting a level 11 enemy, parties with dragons up to level 13 will gain the full amount of experience from it, parties with a high level of 14 will gain 75%, level 15 max dragons will gain 50%, level 16 max ones will gain only 25%, and all parties with dragons level 17 and above will get 0 experience from the level 11 enemy. Every dragon should gain the same amount of experience, so if you bring a level 25 dragon and a level 1 dragon to the Training Fields (levels 1-3 zone), both dragons get 0 experience due to the presence of the level 25 dragon.
Victory chain bonus
The victory chain bonus, acquired by successfully fighting consecutive battles in a zone where your dragons' levels fall underneath or within the specified levels, can give you 5%, 10%, 15%, or 20% increased experience. Nothing's going to stop you from going to a zone earlier than the recommended level, but you don't necessarily get extra experience from doing so. (It's possible if you visit a zone such as the Forgotten Cave or Bamboo Falls early where a low level enemy from a previous zone appears, and then you avoid some level advantage penalty while gaining a chain bonus - but that's not always relevant.)
Note that the 5% bonus applies on the very first battle, so if you qualify for the victory chain experience bonus, it's actually impossible to get +0% bonus chain experience. This bonus is applied to the total experience of the enemy pack after the level advantage penalty has been taken into account and all of the total remaining experience has been added into a single sum.
Event bonus experience
Drakeharvest, Frigidfin Expedition, Sunparched Prowl, Springswarm, and Warrior's Way give a 50% bonus to the total amount of XP earned in a battle. This bonus is applied after after the level advantage penalty has been taken into account and all of the total remaining experience has been added into a single sum. It stacks multiplicatively with other boosts (such as the victory chain multiplier).
Total battle experience with bonuses
The total experience yield after applying all relevant bonuses is floor(((1 + bonus % / 100) for each bonus) * total enemy experience). To take the floor of a number, you simply round down to the nearest whole number. For example, floor(8.9999) = 8, not 9. So, if you're at the 15% bonus on your experience chain, you would multiply your total enemy experience by 1.15, and then you would round down to the nearest whole number. If there is also a 50% XP boost event active, you'd take total enemy experience * 1.15 * 1.5, then round down to the nearest whole number.
Every dragon in your party gets the full total experience amount. Using 2 dragons of the same level will award each of them the same experience as using a third of the same level.

To summarize:
- Individual enemy experience = floor (individual base enemy experience * level advantage penalty multiplier)
- Total enemy experience = The sum of all individual enemy experience in a pack
- Total zone experience = floor (total enemy experience * experience victory chain bonus multiplier * event experience boost multiplier)
- Total experience final amount is awarded to each dragon in the party, not divided between them.
---
For example, if there are four enemies, two of which are worth 400 experience, and the other two of which are worth 0 experience due to a level penalty, the total experience for that pack is 400 + 400 + 0 + 0, which is 800 experience. You would then apply the victory chain bonus multiplier, if any; without a victory chain bonus, the multiplier is 1. If a 50% XP boost event is active, you would multiply that amount by 1.5; otherwise, the multiplier is 1. At the very end, after you're done multiplying all the bonuses, you would round down to the nearest whole number. (1000.1 and 1000.9 both round down to the nearest whole number, 1000.)
Note that most of the time, if you have a level advantage penalty, you will not qualify for the experience chain bonus due to the inherent level gap. There are a few cases where this is not true, because some zones contain enemies that were found in previous zones, and this is the only time where you might experience both the chain bonus and level penalty multipliers within the same pack. Some such enemies are the Crowned Bonepriest (Scorched Forest, Sandswept Delta) and Storm Seeker (Sandswept Delta, Harpy's Roost).
Known bugs
- Sometimes, a dragon in your party will not gain experience when it should. This is caused by lag with the server's processes, and there is nothing you can do but hope the developers fix it somehow. It is a rare occurrence, but just so you are aware, it can happen.
- I have compared data between having the Clan Energy bonus and not having a bonus, and the amount of experience gained is the same, despite the fact that the well-fed status (having over 80% energy for 3 or more consecutive days) supposedly grants +15% Battle Experience. The +15% Battle Experience bonus does not apply.
Archived bugs
- Level 25 dragons used to display the wrong amount of accumulated experience. This was just a visual bug. Now, their experience bars simply display as "Max Level".
