Power Icons Legend

Overview

Many video games which give the player a variety of abilities will use icons or symbols to allow players to identify individual powers at a glance, City of Heroes included. However, unlike many of these games, City of Heroes not only uses these icons to quickly denote individual powers, but also to convey the effects and usage of the powers.

A power icon in City of Heroes has three important components: the inner symbol, the border, and the color. The inner symbol indicates one or more of the powers' effects. The border indicates whether the power requires a target to use and whether it affects an area or a single target. Most powers' borders do not, unfortunately, indicate whether the power affects teammates or enemies; this information must be extrapolated by looking at the inner symbol (i.e. if the inner symbol denotes a positive effect, the power most likely affects allies or the caster) The color of an icon indicates the power set that the power belongs to; every power set has its own unique combination of background and foreground colors, although some colors are shared between primary or secondary power sets and Ancillary Power Pools with similar themes, though never within the same archetype. This is done to reduce the footprint of the City of Heroes installation; by having Frozen Armor use the exact same icon in the Ice Armor, Cold Mastery, and Ice Mastery sets, one icon file provides the art for 3 powers, reducing the size of the City of Heroes install.

Borders

Border	Description	Example
	An icon without a border indicates that the power only affects the caster.	Reconstruction, Unyielding
	The power is single target; it will only affect the currently targeted entity.	Deflection Shield, Power Blast
	The power affects the target, as well as every valid target (up to the target's target limit) within a conical area in front of the caster. The exact dimensions of the cone area depend on the power.	Shadow Maul, Breath of Fire
	The power does not require a target; it affects every valid target (up to the power's target limit) within a spherical area centered on the caster. The exact radius of the sphere depends on the power.	Inferno, Healing Aura
	The power affects the current target, as well as every valid target (up to the power's target limit) within a spherical area centered on the target. The exact radius of the sphere depends on the power.	Exploding Arrow, Snow Storm
	The power does not require a target; it affects every teammate within a spherical area centered on the caster, including the caster itself.	Assault, Group Invisibility
	The power affects every target (up to the power's target limit) in a spherical area centered around the targeted teammate. The targeted teammate may or may not be affected, depending on whether the power's effect is a positive or negative one.	Disruption Field
	The power summons a separate entity at a selected location. Some powers allow the caster to choose the location, while others simply summon the new entity at the caster's feet.	Animate Stone, Summon Striker
	The power affects every valid target (up to the power's target limit) within a spherical area centered around a location. Some powers allow the caster to choose the location, while others automatically set the location to be the same as the caster's at activation.	Spirit Tree, Burn

Inner Symbols - Buffs

The following inner symbols denote powers that grant the caster or his allies buffs to various attributes.

Symbol	Description	Example	Notes
	Increases accuracy or tohit.	Aim	Most powers that buff tohit also buff damage, so the use of this symbol normally means that the power is either an accuracy buff, or the tohit buff is particularly large.
	Increases damage.	Build Up
	Increases defense.	Dispersion Bubble
	Increases defense against powers typed "melee".	Ninja Reflexes
	Increases defense against powers typed "ranged".	Combat Training: Defensive
	Increases defense to powers typed "area of effect" (AoE).	Evasion
	Increases defense and tohit.	Invincibility
	Increases maximum hit points	Dull Pain	Would seem to indicate a healing over time effect (HoT), but is normally used to indicate a buff to maximum HP. In Issue 13 a power was finally added that actually was a HoT, but only when used by one archetype, and then only in PvE.
	Healing power; restores lost hit points	Heal Other
	Restores lost endurance.	Transference	Also used in the icon for Conserve Power, which reduces the endurance cost of all powers while active.
	Large buff to defensive attributes.	Light Form	Typically used for tier 9 powers in defensive power sets. Powers that use this symbol generally grant such a large buff to defenses that the affected character is effectively undefeatable under normal circumstances, hence the colloquial term "god mode power."
	Increases both offensive and defensive attributes.	Vengeance
	Increases the maximum activation range on non-melee powers while active.	Boost Range	Boost Range is the only power that uses this symbol, and indeed that has this effect.
	Reduces the recharge time of all powers while active.	Hasten
	Increases the rate at which lost hit points are naturally recovered over time.	Instant Healing
	Increases the rate at which spent endurance is naturally recovered over time.	Stamina
	Increases the duration or strength of mez effects and most buff and debuff effects.	Power Boost
	Increases the running speed of the target.	Speed Boost
	Increases running speed and jump height	Sprint	This is the Sprint symbol; the only powers that use the symbol are Sprint and its Prestige variations.
	Increase to jump height and speed.	Inertial Reduction
	Increase to jump height and speed.	Super Jump	The only power that uses this symbol is Super Jump.
	Grants the target the power of Flight.	Fly

Inner Symbols - Control

The following inner symbols denote powers that have control effects.

Symbol	Description	Example	Notes
	Afflicts the target with a Hold control effect.	Dominate	Held targets cannot use powers or move.
	Afflicts the target with a Disorient control effect.	Screech	Disoriented targets cannot use powers, but can still move, albeit at an extremely reduced rate. Also known as "Stun."
	Afflicts the target with an Immobilization control effect.	Web Grenade	Immobilized targets cannot move, but can still use powers as normal.
	Afflicts the target with a Sleep control effect.	Salt Crystals	Sleeping targets cannot use powers or move, but will immediately awake if damaged, healed, or moved.
	Afflicts the target with a Confuse control effect.	Deceive
	Afflicts the target with a Fear control effect.	Feared enemies cannot use powers or move unless they are attacked.
	Repels affected targets away from the caster.	Force Bubble
	Reduces the movement speed of the target.	Caltrops
	Increases the recharge time of all the target's powers.	Poison Trap
	Reduces the target's movement speed and increases the recharge time of all its powers.	Shiver	"Slow" can refer to a power that reduces movement speed, increases recharge time, or both. "Snare" is used for powers that only reduce movement speed. There is no generally agreed upon term for powers that only increase recharge time.
	Afflicts the target with a taunt control effect.	Taunt	Taunted targets can only use powers to attack the entity that taunted them. In the event that more than one entity uses a taunt effect on the same target, the target will only be able to attack the entity with the stronger taunt effect.
	The power can knock down the target, leaving them unable to act until they regain their footing. Some powers are strong enough to send the target flying away from the caster instead of just knocking them off their feet.	Power Thrust	Knockdown is just low-grade knockback. A power that normally does knockdown can cause knockback if used on a sufficiently weak target or if slotted for knockback, and a power that normally does knockback can cause knockdown if used against a sufficiently strong target.
	The power can cause the target to fall down where they stand, unable to act until they regain their footing.	Energy Torrent	Same notes from above apply.
	The power can send the target flying straight up in the air. Stronger enemies may only fall down where they stand.	Lift	Same notes as above two symbols apply, with the exception that the target can be sent flying straight up into the air instead of away from the caster.

Inner Symbols - Damage

Symbol	Description	Example	Notes

Comments

There are many internal inconsistencies within the game that makes some of this page guesswork rather than fact. If the power rings and the power symbols were consistent within the game, it would be easy to identify what a power does just by it's icon.
