If you can't even see that the 55% is the amount of damage you receive then you should stop doing math before you hurt yourself. Your effective health is directly affected by the amount of damage you take and not by the amount of damage you do not take. You can, however, calculate the amount of damage you take by substracting the amount you do not take from the damage you would take without mitigation.
Basic math class 2:
Health: 3000
Damage per hit: 3000
Hits needed to kill the target: health / damage per hit = amount of hits
---> 3000 / 3000 = 1.
Now we add 45% damage reduction:
Damage done per hit after mitigation: damage per hit - damage absorbed = actual damage per hit
---> 3000 - (3000 * 0.45) = 3000 - 1350 = 1650 (This result equals 55% of the base value)
Now we calculate how many hits we need after mitigation kicks in:
Hits needed to kill the target: Health / damage per hit = amount of hits
---> 3000 / 1650 = 1,82
Last step, calculating the amount of damage the hits would have done if there was no mitigation (also known as effective health):
Amount of hits * Damage per hit = total, unmitigated damage (---> effective health)
---> 1,82 * 3000 = 5454,55
5454,55 is your effective health.
The short form of this formula is:
Health / (100% - damage mitigation%) = effective health
---> 3000 / (100% - 45%) = 3000 / 55% = 5454,55
If you are unable to follow this formula, refer to basic math class 1 on page 5 in this thread. It explains the same thing in a different way with less numbers and more words.
You are welcome.
lets take your example and plug in another #...
Health: 3000
Damage per hit: 3000
Hits needed to kill the target: health / damage per hit = amount of hits
---> 3000 / 3000 = 1.
Now we add 45% damage reduction:
Damage done per hit after mitigation: damage per hit - damage absorbed = actual damage per hit
---> 3000 - (3000 * 0.45) = 3000 - 1350 = 1650 (This result equals 55% of the base value)"
lets use...
Health: 3000
Damage per hit: 7000
Hits needed to kill the target: health / damage per hit = amount of hits
----> 3000 / 7000 =
1
Now we add 45% damage reduction:
Damage done per hit after mitigation: damage per hit - damage absorbed = actual damage per hit
---> 7000 - (7000 * 0.45) = 7000 - 3150 =
3150 (this result equals 105% of the base value)
*because 3000 would be 100% of the base value correct?
NEXT STEP
Now we calculate how many hits we need after mitigation kicks in:
Hits needed to kill the target: Health / damage per hit = amount of hits
---> 3000 / 1650 = 1,82
Last step, calculating the amount of damage the hits would have done if there was no mitigation (also known as effective health):
Amount of hits * Damage per hit = total, unmitigated damage (---> effective health)
---> 1,82 * 3000 = 5454,55
5454,55 is your effective health.
Now we calculate how many hits we need after mitigation kicks in:
Hits needed to kill the target: Health / damage per hit = amount of hits
---> 3000/3150 =
0.95Last step, calculating the amount of damage the hits would have done if there was no mitigation (also known as
effective health):
Amount of hits * Damage per hit = total, unmitigated damage (--->
effective health)
----> 0.95 * 7000 =
6650.00
6650.00 is your effective health
This is why you cannot use the OP's formula, because you don't know what the damage is.The only variable you do have, is how much more damage you can take, and that is why if you have 45% resilience then theoretically you can resist that much more damage, so you multiply that by your health.
3000 health * 1.45 = 4350 effective health.
