Superior Rune of the Scholar or Ruby orb
If you can keep your health above 90%, scholar are better.
I prefer ruby orbs better as every rune you gant keep ur health over 90%
Realistically, stats can only go so far. You can say one rune or gem is better than another, but only if you can make it better. Scholar’s Runes I believe have been calculated to be slightly better provided 90% or better health is maintained. If you actually think you are capable of keeping your health that high throughout the entire duration of any fight, then Scholar’s would be a better choice for you.
However, realistically, if you take even one hit, particularly on a berserker setup, you’re automatically sub-par compared to Ruby Orbs. And as such, while Scholar’s Runes can be better than Ruby Orbs, I would venture a guess that for 98% of all situations, or even 98% of a single fight, Ruby Orbs will outshine the Scholar’s Runes considering how easily one can lose health.
However, you can consider getting the best of both worlds. At the time of me writing this, 6 Ruby Orbs cost less than 1/3 the price of a single Scholar Rune. Especially if you are not as familiar with a berserker setup, you should start with those. As you practice, keep an eye on your playing, and where your health pool is sitting as you get better. If, with practice, you are actually finding that you’re able to keep a high health pool, then you might give Scholar’s a try.
However, considering Scholars Runes cost close to 4 gold per rune, it is a very expensive try. I think you’ll find the benefits of those 2% of cases not to be noticeable, not worth 24 gold, and will probably just stick with Ruby Orbs once you try them.
For the money and below 90% hp, Orbs are better. I vote orbs.
If you are above 90% about 25% of time (exact number depends on stats) Scholar and Orbs are equal. To be on safe-side you should be above 90% at least 33% of time.
What this means that if there’s one boss in the dungeon where you barely get hit, Scholar is most likely better. Unless you get full focus every time it’s very difficult to not stay above 90% at some point.
