The '''Pool of Reflection''' (generally called "PoR" or "Pool") is a yellow-colored health shrine pool that grants a 25% buff to experience gain that lasts for some set amount of experience, or until a character dies. This feature was added to Diablo III in [[version 2.0.1]] in February 2014, and is also present in [[Reaper of Souls]].

Pools replace some small percent of health pools (about every 10th pool) and grant a bonus to experience gain, but no healing bonus at all. The bonus from the Pool does not get added and multiplied in with other experience bonuses, but instead works to modify the gross experience gained by .25. If a character gains 100 million expFor example, if the "Bonus Pool Remaining" said 20m, the effect would add 20m exp to the next 80m exp gained.  Each Pool bonus adds 25 million % bonus experience on top of thatall other exp gained for some discrete amount of EXP. The bonus can stack up to ten times, over potentially lasting about 4 levels, though the duration amount varies due to the differing amounts of the bonusexp required for each level.

A player can stack up to 10 bonuses from Pools, which is enough to last for the next 3-4 about four level ups. Additional Pools added before the bonus is depleted will stack on, but never exceed though the maximum of 10 stacked bonusamount varies due to differing exp required for level progression. As Since higher level characters require much more experience to advance a result high level characters who are not dying (such as in Hardcore) wind up with essentially , a permanent single Pool of Reflection can spread its bonus, since it's virtually impossible to play gain that much for tens of millions of experience without encountering more Pools in the processfor a character on an account with high Paragon Levels.

Since higher As a result high level characters require much more experience to advance who are not dying (such as in Hardcore) wind up with essentially a level, a single permanent Pool of Reflection can spread its bonus for tens of millions of , since it's virtually impossible to gain that much experience for a character on an account with high Paragon Levelswithout encountering more Pools in the process. At the same time, a Pool used by a low level character will last a very short time, sometimes a minute or less if the character is killing quickly and using other +experience gear.

The displayed text is oddly-presented. The bonus number refers to how much extra experience on top of the normal amount the pool is providing. As you To calculate how much experience a character can see in gain before exhausing the example above, this character (from the Reaper of Souls beta) has just started gaining towards Paragon 134.  [[File:Pool-of-reflection-tooltip-max.jpg|right|thumb|400px|Two-shot sequence showing the max possible 10 stack bonus.]]The full bar requires about 200m exp, and the dot showing the end of multiply the "Bonus Pool of Reflection bonus is about 8 bars along the 10 bar display. That's roughly 160m experience, thus the 32m bonus is 25% added on top of the experience gained. Thus 4 x 32m = 128m + 32m (pool bonus) = 160mRemaining" number by 5.

Thus players who want to figure how much total exp [[File:Pool-of-reflection-tooltip-max.jpg|right|thumb|400px|Two-shot sequence showing the max possible 10 stack bonus.]]Explanation: As you see in the screenshot above, this character (from the can gain before Reaper of Souls beta) has just started gaining towards Paragon 134, and requires around 200m for the next level. The Pool bonus ends should is 25% on top of other exp gained, and it says 32m for the pool. So multiply 32 x 4 = 128m + 32m (pool bonus) = 160m. Which is right about 8 bars along the "Bonus Pool Remaining" number by 5 way to figure how much 10 bars / 200m experience they can gain before exhausting the Pool bonus.

Yes, a bit confusing and weird in display. Fortunately the dot on the experience bar is simple and visual.
