ability cooldowns are the length of time that a player must wait before being able to use a specific ability. Many players will notice that there chosen abilities are not available for use despite the player’s desire to utilize such an ability. The player may begin to feel as if the cooldown for the desired ability is too long, especially if abilities like grenades or melee abilities doesnt quickly return to allow for the player to land the intended attack.
There are actualy three different ability tracks that the game tracks, each of which is different from the old Discipline and Strength stats. Additionally, there is a difference between stats that reduce the base cooldown of an ability versus stats that increase the returns of energy for those abilities outside of the sources of that energy. Understanding this difference are half the understanding of ability cooldowns.
How Ability Cooldowns Work and How to Use the Calculator
The calculator that is provide on this page will calculate the math for you regarding your ability cooldown statistics. In order to calculate these stats, you will have to provide the game with several different input. Your base cooldown families, your three stats, the regen package that you are using, and the length of the activity window will be required as the player input each of these values.
Each of these values will impact a specific calculation that the calculator makes within. For example, your base cooldown will impact the base cooldown calculation before any stats are applied to that cooldown, your stats will impact how much those stats will reduce your cooldown, the regen package will determine whether you receive one-time cooldown refund or continual returns of energy to your abilities, and the activity length will determine whether you are calculating your cooldowns for a short duel or for a long period of activity with a boss. While investing in stats will provide you with beneficial effects, the difference between a tier 7 stat investment and a tier 10 stat investment is often much more less than the difference between having no regen package versus having a regen package that provides refunds of twenty percent of your energy returns.
Many players do not consider this because they focus upon investing their stats into a single armor piece, instead of considering the benefits of selecting the correct regen package. An external energy scalar that exceeds 100 stats is a consideration for many players, but only provides benefit for those who are already casting or spending armor charge. Any player who is not generating their orbs or spending armor charge will experience no benefit from stats beyond those require to enable their abilities to return.
The tables that are provide on this page will help to show the different cooldowns for each base family, as well as the returns that are applied to each of the different regen packages. For instance, abilities like fast dodge or fast thruster will have base cooldowns of 29 or 30 seconds, while abilities like long glacier grenade will have a base cooldown of 152 seconds. These cooldown statistics will help you to decide whether your character and abilities are to continually utilize the skill or to have the skill available for certain instances during play.
The calculator will provide you with both the cooldown that will be applied to your ability, as well as the number of times that you can utilize your ability during the chosen length of activity. A common mistake that many players make is treating each ability as if it is the same as each of the other abilities. For instance, a one second effect for a grenade will not be the same as a fifteen second effect for a rift field; the power of each effect is not the same.
Additionally, the length of the activity window will have an impact upon your abilities. For instance, a ninety second window will have different benefits from a twenty four hundred and forty second activity. The grade that is provide at the bottom of the page will compare these two scenarios, and provide you with an understanding of which scenarios is the best for your specific length of activity.
Instead of measuring the success of your chosen build by the cooldown length of your least powerful ability, you should of be measuring the success of your build by how many times you can use that ability during your activity. For instance, an ability with a cooldown of forty seconds will not be effective if the fight does not last three uses of that ability. An effectiveness of abilities that return every seventy eight seconds will be provide by the regen package that you utilize to provide energy to those abilities.
The calculator will help you to determine these values and understand how many times you can use each ability in your game.
