Summoner's War: Rune + Vs +% Comparison

Below is a simple table of runes and their value after being upgraded to +6, which is a generic starting point that I bring all of my runes to

	HP	HP%	ATK	ATK%	DEF	DEF%	Crit Rate
3*	550	16%	37	16%	37	16%	15%
2*	430	8%	29	8%	29	8%	8%

Now let us get into the reasons why I created the table above.  The answer is simple.  I want to maximize the effect of the runes I place in slots 2,4, and 6.  Crit rate does not need to be compared, but I added it to the table while I was collecting information because I wanted to know if it was a worthwhile investment for rune #4 (Totally is and it should be used when having at least one Blade rune set).

Since hard mode is the best I can achieve at the moment,  3* is the best I can hope to achieve through farming, unless I get lucky in the giant dungeon, but that is another story.

Now let us get into the actual discussion, shall we?

Do I use HP or HP%?:

This question is figured out by a simple formula.  If you divide the HP rune amount by the decimal value of the HP% rune amount, then you will find out the base HP the monster must have in order for both runes to have the same effect.  This means you will now know the threshold between when one rune is better than the other.  Let's look at the math

3* HP rune = 550
3* HP% rune = 16% = 0.16 in decimal
2* HP% rune = 8% = 0.08 in decimal

550 / 0.16 = 3437.5 HP

Any monster with over 3438 BASE HP will benefit more from the HP% rune.

3* HP rune vs 3* HP% rune = 3437.5 HP

3* HP rune vs 2* HP% rune = 6875 HP

2* HP rune vs 2* HP% rune = 5375 HP

Do I use ATK or ATK%?: (also applies to DEF)

We can use the same formula from the HP section, so let's get to it!

3* + rune vs 3* % rune = 231.25

3* + rune vs 2* % rune = 462.5

2* + rune vs 2* % rune = 362.5

Overall Comparison:

In early game, you can safely sell all % runes for base stats.  Even when they are upgraded to +6, they still fall short of the benefit that can be achieved by a regular + rune.
