Experience

Experience is accrued by defeating enemies and completing missions.

Experience Table

This table indicates the experience requirements for each level in both City of Heroes and City of Villains.

Experience Distribution and Team Bonuses

Overview

The experience that a character gets while on a team is affected by the team's size, by his level relative to the enemies, and by his level relative to his teammates. Larger teams get a higher XP multiplier, but the rewards also get split more ways. Lower-level characters get more XP from each critter (since the critters are comparably tougher), but the game also gives greater-than-average shares of XP to the higher-level characters in the team (since they are presumed to be doing most of the work).

Detailed Breakdown

First, determine if any team members are too low to get or affect XP. The game completely ignores all members whose combat levels are too far below the highest member's level. Ignored members not only get no experience whatsoever, but experience is generated and distributed among the rest as if the ignored characters weren't even there. The maximum level spread depends on the highest member's level, and although full data haven't been published, the spread is known to be strictest for very low- and very high-level teams and loosest for teams where the highest member is around level 25.

Highest Teammate Level	Max Spread
~25	9
?	?
1-5, 45-50	5

Second, determine the team's average combat level and total weight. These figures will come in handy later, and they only need to be calculated once.

2.a. Calculate the team's average combat level, dropping fractions.

2.b. Look up the weights of all team members by comparing their combat levels to the team's average in the following table. Add these together to get the team's total weight.

Char Lvl Relative   to Team Avg.	Weight		Char Lvl Relative   to Team Avg.	Weight
-5 and below	0		+3	1.15
-4	0.45		+4	1.25
-3	0.68		+5	1.5
-2	0.85		+6	3
-1	0.95		+7	6
0	1		+8	9
+1	1.05		+9	12
+2	1.1		+10	18

Third, for each character in the team:

3.a. Look up the standard XP reward that that character would get if he were soloing at his actual level and he defeated an equal-level version of the enemy in question.

3.b. Adjust the reward based on the enemy's actual level relative to the character's current combat level:

Critter's Relative Level	XP Multiplier
-5 or lower	0
-4	0.2
-3	0.4
-2	0.6
-1	0.8
0	1
+1	1.2
+2	1.4
+3	1.65
+4	1.9
+5 or higher	2

3.c. Increase the reward based on team size:

Team Size	XP Multiplier
1	1
2	1.25
3	1.5
4	1.8
5	2
6	2.1
7	2.2
8	2.5

3.d. Multiply the reward by the ratio of that one character's weight to the team's total weight. (Use the table back in step 2.b. again.)

Critter XP Rewards

These are the base XP reward values for each rank and level of critter. Some of the more difficult critters have a bonus modifier that increases the amount of XP rewarded.
