Many of the questions most commonly asked by HeroStats users are related directly to a particular City of Heroes/Villains power. The term "power" here refers not only to actual player powers, but also NPC attacks, inspirations, procs from IOs, etc. This is only a partial list, not all powers are covered here.

This list is current (though not complete) as of April 18, 2010.

Incorrect Statistics Issues

The following section lists issues that prevent HeroStats from correctly tracking statistics.

Controller Accuracy - Containment

The Controller inherent power Containment can cause inflated accuracy for many powers, because Containment duplicates the damage message for those powers. Since this can affect most Controller powers, those powers are not listed individually below. This affects only "Power Accuracy" statistics, not "Player Accuracy".

Missing or Incorrect Power Name in Messages

The power messages either do not contain the power name or have the wrong name, so HeroStats cannot reliably determine which power generated the message. This affects some or all of the messages generated by the following powers:

• Ablating Strike
• Absorb Pain
• Accelerate Metabolism
• Acid Arrow (NPC Ninja Mastermind version)
• Adrenalin Boost (NPC version)
• Aim
• Amplify
• Arachnos Shotgun Frag Grenade (NPC)
• Beguile
• Biological Mutagens
• Black Dwarf Drain
• Blazing Arrow (Blaster only, Defender version is correct)
• Calling the Wolf
• Cauterize
• Challenge
• Crushing Field
• Cryonite Armor
• Essence of the Earth (inspiration)
• Fly
• Frozen Armor
• Glowing Touch
• Healing Aura
• Heal Other
• Kuji-In Retsu
• Nimble Slash
• Power Slice
• Rock Armor
• Share Pain
• Smoke Flash
• Plasma Shield (Buff received message)
• Radiant Aura
• Rise to the Challenge
• Thermal Shield (Corruptor version)
• Typhoon's Edge
• Vengeful Slice
• Warrior's Challenge
• Warmth
• There is no power name in messages of the form "{Source} {AttackWord} {Target} for {Damage} points of {DamageType} damage". These are generated with various attack words like "blasts", "hits", "shoots", or "smacks". Each attack word is generated by multiple powers, so there's no way to distinguish between them. This is sometimes followed by a debuff message (i.e. "and slows you"), which again is generated by multiple powers.
• The message "You are now Stealthy." is used by many different powers, so there's no way to distinguish between them.
• Most proc IO messages are missing a power name to identify them.

Missing or Invalid Source/Target Name in Messages

The power messages either do not contain the name of the source or target of the power (or have the wrong name), so HeroStats cannot reliably determine the source or target name. This affects some or all of the messages generated by the following powers:

• Accelerate Metabolism
• Achilles' Heel: Chance for Resistance Debuff
• Biological Mutagens
• Bile Spray (Dominator version has player name rather than target name)
• Black Dwarf Mire (Damage-taken message has player name rather than target name)
• Fire Blast (Ninja pet version has "you" rather than target name)
• Grant Invisibility (No target name shown to caster)
• Glacial Shield (No source name shown to target)
• Ice Shield (No source name shown to target)
• Plasma Shield
• Thermal Shield (Corruptor version)
• Siphon Power (No source name shown to target)
• Speed Boost (Corruptor version has no target name shown to caster)

Multiple Identical Hit Messages - Multiple Target

There are multiple identical damage messages generated by a multiple-target power. Accuracy cannot be tracked since there is no way to tell if two messages mean one target hit twice, or two targets hit once each. This affects the following powers:

• Arctic Breath
• Atomic Blast
• Bullet Rain
• Crushing Field
• Empty Clips
• Fire Breath
• Flamethrower
• Frost
• Frost Breath
• Hail of Bullets
• Sands of Mu
• Shadow Maul

No Hit Message

There are no messages indicating that the power has hit a target, so HeroStats cannot track damage dealt or buffs/debuffs. This affects messages generated by the following powers:

• Blizzard
• Detonator
• Energy Manipulator: Chance to Stun
• Executioners Contract: Disorient Bonus
• Freezing Rain
• Fulcrum Shift (Corruptor version)
• Ice Storm
• Pounding Slugfest: Disorient Bonus
• Rain of Arrows
• Thunder Clap (Controller version)

No Unique Activation Message

There is not a single unique message generated for activation of the power. Some of these powers may have activation messages, but more than one is generated if a legal target for the power is nearby. This affects messages generated by the following powers:

• Arctic Fog
• Blizzard (Corruptor version)
• Chilling Embrace
• Choking Cloud
• Darkest Night
• Dispersion Bubble
• Disruption Field
• Enervating Field
• Group Energy Flight
• Group Fly
• Hurricane
• Invincibility
• Radiation Infection
• Rise to the Challenge
• Shadow Fall
• Snow Storm
• Steamy Mist
• Sonic Dispersion

Player Accuracy Statistic - Secondary Effects

"Player Accuracy" for many powers with a secondary effect is incorrect. This is because the hit-miss combat log messages for these powers contain identical messages for both the main power and the secondary effect. These powers are not individually listed below. This affects only "Player Accuracy" statistics, not "Power Accuracy".

Inconsistent/Incorrect Message Issues

For some powers, it is possible to track proper statistics in HeroStats, but the log messages still contain errors or inconsistencies. These powers are listed below. None of these should affect HeroStats users directly, but they are listed here for completeness.

Multiple Identical Hit Messages - Single Target

There are multiple identical damage messages generated by a single-target power. Accuracy can still be tracked by the activation and miss messages rather than the damage messages. This affects the following powers:

• Ablating Strike
• Barb Swipe
• Burst
• Char
• Chilblain
• Crey CBX-9 Pistol
• Crush
• Dual Wield
• Electric Fence
• Entangle
• Fettering Nimbus
• Flurry
• Frenzy
• Gloom
• Gravimetric Snare
• Gravity Distortion
• Incinerate
• Longfang
• Nimble Slash
• Nullifier Gun Prototype
• Nullifier Gun Mk I
• Poisonous Ray
• Moderate Opening
• Particle Cannon
• Proton Volley
• Ring of Fire
• Scream

• Siphon Power
• Soul Storm
• Stolen Immobilizer Ray
• Stolen SMG
• Stone Prison
• Strangler
• Suppression
• Swipe
• Thermite Cannon
