ECP System
Every character in Elsword has their own unique features that set them apart from other characters.
ECP System
ECP (Energy of Colorless Point) is a system exclusive to Rose. The system interface is displayed below the MP bar.
ECP Gauge
The yellow bar below your MP bar contains 70 ECP, which certain skills called ECP Using Skills will use instead of MP. ECP points will also be consumed when switching weapons during combos or performing the finisher of her ground 
combos, as well as by a few additional skills. If any ECP is missing, it will slowly start recovering at 5 points per second.
Once the gauge is completely depleted, Over Strike will be activated.
Most ECP Using Skills cost exactly 35 ECP, not counting skill traits. This makes it possible to activate Over Strike instantly by using any 2 ECP Using Skills in a row, assuming that your gauge is full.
Over Strike
While Over Strike is active, you will gain certain effects for a duration. You can not use most ECP Using Skills while Over Strike is active unless through specific passive effects, but Weapon Switching is still allowed. The ECP gauge will recover faster during Over Strike, at 10 points per second.
| Mode | Over Strike | ||||
|---|---|---|---|---|---|
| MP Gain on Attacking Increase | Special Active Skill Damage Increase | Critical Damage Increase | Command Damage Increase | Duration | |
| PvE | 10% | 20% | 15% | 150% | 10 Seconds |
| PvP | 20% | ||||
Weapon Switching
|
Rose has the choice of utilizing 4 different firearms: Revolvers, Muskets, Auto-guns, or Hand Cannons. For manual switching outside of combat, press 'V' key (default) to switch to the next weapon in a clockwise direction. |
Revolvers: Basic weapons of Rose. Fires quick singular shots at set intervals. Critical activation chance is high and critical damage is increased by 25%. The weapon is mid-range.
Muskets: Similar to Revolvers but does more damage, fires slower, has the longest range, and will penetrate through all enemies within range.
Auto-guns: Firearm which fires quick multiple shots which burns 2 MP each at set intervals but damage is the lowest and range is about the same as Hand Cannons.
Hand Cannons: Firearm which deals the highest damage and is also the slowest but range of the blast is a bit lower than Revolvers.
During the [Weapon Switch]
Depending on the command input after the applied attack, weapons will switch.
Revolvers: V + 
Muskets: V + 
Auto-guns: V + 
Hand Cannons: V + 
combo, you are able to switch weapons by holding V and tapping the respective arrow key.
Weapon Locking
You can lock up to 2 specfic weapons if you dislike using them. Locked weapons will not be switched to if you switch with the 'V' Key. To lock weapons, enter your equipment page ('U' default) and right click the weapon icon that you want to lock. If the combo extension uses the specific weapon that you have locked, the weapon will only be switched during the combo and then it will change back to the original weapon you were using.

Tips and Details
- While having insufficient ECP may prevent you from using ECP Using Skills, performing a finisher or switching weapons does not share the same limitation and allows you to burn off extra ECP in order to attain Over Strike when necessary.
- The effect values of Over Strike Mode are never shown in-game anywhere; the current values are based on a patch note that changed some of these values, and thus listed the old/new values for players to see.
- Despite this, in-game testing shows the Critical Damage Increase is actually 15%, not 10% as is claimed there.
- Almost every ECP Using Skill costs 35 ECP (with Prime Operator's G-skills core activation being an exception), allowing you to cast any 2 of them and enter Over Strike instantly, assuming no consumption traits were applied.
- You will still enter Over Strike while casting 2 ECP Using Skills with a slight delay between them, despite every each of them costing 35 ECP (without the use of Light or Critical traits), the maximum of ECP being 70, and the ECP gauge being continuously recovered, which could lead you to having a few extra ECP rather than 0 like the requirement says.
- The maximum possible delay seems to be set individually for each skill, since skills like Booster Cannon give you more time to land and use another skill in order to activate Over Strike.
- You will still enter Over Strike while casting 2 ECP Using Skills with a slight delay between them, despite every each of them costing 35 ECP (without the use of Light or Critical traits), the maximum of ECP being 70, and the ECP gauge being continuously recovered, which could lead you to having a few extra ECP rather than 0 like the requirement says.
- While the general rule is that you cannot use ECP Using Skills while in Over Strike Mode anymore, almost every path gets a passive that allows you to do so under certain conditions or drawbacks, if at all. Only Tempest Burster still gets locked out of all her ECP Using Skills upon entering Over Strike.
Trivia
- Attempting to lock the weapon Rose is currently wielding will result in her saying "It's the weapon you are currently using, but...?" in the form of a text box.
- For some reason, despite switching to another weapon, Rose will always appear with the default weapon of each path on the Character Selection screen.
