Final damage (FD)
is a mysterious stat to many players, old or new because the game never really explain much about it.
Before the sea dragon patch, final damage used to be calculated in this way:
Each hit + x final damage
If you have x final damage, you will see an increase of x damage per hit to your damaging skills. So basically, the old calculation of final damage benefits only skills with multiple hits.
However, after the Sea Dragon patch in korea last year (Dragon Nest Infinity patch), final damage calculation have been revamped.
Recently, Catastrophe update has been final damage being boosted.
WHAT IS FINAL DAMAGE?
The korean developer gives the following info and examples with regard to the change of final damage calculation in the official update notice:
1. A level 40 player with 300 FD hits another Lv40 target - deal an extra 12.35 % damage.
2. A level 40 player with 700 FD hits another Lv40 target - deal an extra 65.24 % damage.
3. The damage boost due to FD is dependant on the level of the target: higher damage boost to lower level targets.
4. The maximum additional damage possible from FD is 100% (double damage)
5. The effect of final damage is nerfed in pvp.
First, it must be noted that now all skills regardless of number of hit, enjoys the SAME % of damage increase.
The table below shows the final damage value, with their respective % damage increase, versus target of lvl24, 32, 40 and 50
These information can be plotted as:

HOW TO CONVERT FINAL DAMAGE TO % DAMAGE INCREASE?

Simply key in the final damage and the excel spreadsheet will tell you the % damage boost to lv 40, 50 and 60 targets.
NOTE: there might be some small discrepancy between the value shown in the spreadsheet and the real ingame % damage boost because the equations are obtained by curve fitting. The error normally would not exceed 1%.
GROWTH OF FINAL DAMAGE
The growth of final damage is non-linear in nature.
For example, from the curve for lv40 target, it can be seen there, the % damage increase curve increases very significantly after the point of inflecton at around 350 final damage.
Before that point, the slope of the curve is actually pretty mild and linear, meaning increase of final damage doesn't give much increase of % damage inc.
However, after the point of inflection, the slope of the curve grows exponentially
. A small increase of final damage gives a HUGE increase of % damage inc (for example near 350 final dmg for lvl40 targets)
EFFECT OF TARGET LEVEL
Another interesting properties of Final Damage is that the level of the target actually affects the % damage increase
too. ( see the figure above )
Final damage give more % damage boost if your target is lower level.
For example, a player with 600 FD hits a lv40 monster, deal 46.47% extra damage.
The same player with 600 FD hits a lvl50 monster, deal only 18.56% extra damage.
With a fixed FD value, the damage boost reduces against a target of higher level
In other words, you will need MUCH MORE FD value against high level targets/monsters
to have singificantly damage boost.
To get 100% damage boost against Lv32 monster, you only need about 600 FD.
To get 100% damage boost against Lv40 monster, you will need at least 850 FD.
To get 100% damage boost against Lv50 monster, you will need at least 1300 FD!!!
LIMIT OF FINAL DAMAGE
There is a limit to the % damage inc from FD. [ see the curve above ]
For example, a player with 600 FD hits a lvl 32 monster, deal 100% extra damage.
The same player with a higher 1200 FD hits a lvl32 monster, ALSO deal 100% extra damage.
Boosting FD beyond a certain value doesn't increase the extra damage because of the limit for FD is 100%.
In other words, the damage boost from FD will not go beyond 100%.
FINAL DAMAGE IN PVP
It is also proven in real game test that the effect of FD is nerfed significantly in PVP. The damage increase due to final damage in PVP is almost negligible
Final damage does NOT affect the healing amount
Final damage affects the damage from the summon unit
Final damage is additive to skill plate/heraldry dmg
% (NOT multiplicative)
. For example, if you have 70% final dmg and you use a skill with 20% dmg inc heraldry, the real damage amplification is 70%+20% =90% . (NOT 1.7 * 1.2 = 2.04) [ref 2]
PREVIOUS MISCONCEPTION ON FINAL DAMAGE
At lv40 cap, it was widely believed that the level gap between the player and the target / monster is one of the factor that affects the % extra damage.
This was proven to be INCORRECT when lv50 cap opens.
A lvl40 player with 600 FD, hits a lvl40 monster deal 46.47% extra damage.
A lv50 player with the same 600 FD, hits a lvl40 monster, deal the same 46.47% extra damage.
The LEVEL OF THE PLAYER HAS NO EFFECT on the damage boost from FD.
