Unleash Support is a support gem which causes the supported spell to generate Seals while not being cast. The next time the user casts the spell, the spell will consume the Seals it stored to cast the spell in rapid succession.

Skill functions and interactions

The gem's advanced description specifies (Spell cast time is 10% longer for each time the Spell reoccurs).

While the spell "reoccurs", your character will stand in place while playing the casting animation. Note that the reoccurring spells do not count as being cast by you, and will therefore not trigger any on-cast abilities such as stacks.

Due to how this support gem functions, to achieve maximum DPS potential, casting intervals need to be timed to allow for generation for maximum Seals between casts. As increase cast speed is generally also a DPS increase, using Unleash may be detrimental in some scenarios, and the player should ensure these factors have been compared.

The absolute dps increase from the gem can be calculated from 2 factors, the amount of seal casts per second and the damage reduction:

$\color [rgb]{0.6392156862745098,0.5529411764705883,0.42745098039215684}{\dfrac {1-{\text{less damage}}}{\text{seal cooldown}}}=(1-{\text{less damage}})*{\text{seal casts per second}}={\text{full damage casts}}$

For a level 20 gem this gives you the following properties:

$\color [rgb]{0.6392156862745098,0.5529411764705883,0.42745098039215684}{\dfrac {1-{\text{0.41}}}{\text{0.71 seconds seal cooldown}}}=(1-0.41)*1.41{\text{ seal casts per second}}=0.831{\text{ full damage casts each second}}$

The gems relative damage increase depends on the cast time of the spell it supports:

$\color [rgb]{0.6392156862745098,0.5529411764705883,0.42745098039215684}{\dfrac {\text{full damage casts}}{\text{ manual cast rate}}}={\text{full damage casts}}*{\text{manual cast time}}$

With a level 20 gem this is

$\color [rgb]{0.6392156862745098,0.5529411764705883,0.42745098039215684}{\dfrac {0.831}{\text{ manual cast rate}}}$

So if your PoB says your cast rate is 5.34, then unleash support would increase your dps by 15.56%, if you stand in place and constantly cast.

The gem particularly excels in builds where kiting and movement have precedence over constantly casting, or the cast rate for a spell is relatively low.

For a skill with 0.5 cast time, which means 2 casts per second while standing still, the relative dps increase is 41.55%, if you stand in place and constantly cast.

The maximum dps increase, when you are dodging constantly and only cast the spell when it has 3 seals, would be $\color [rgb]{0.6392156862745098,0.5529411764705883,0.42745098039215684}{3*(100\%-{\text{ damage reduction per seal cast}})=177\%}$ compared to the same amount of dodging and only casting the same spell once and dodging the same amount of time.

Casting the spell constantly does not seem to interrupt seal generation, instead the support gem seems to add an internal cooldown similar to for example es usage storage, but without the visual indication of a clockwise indicator showing when the next seal will be generated.

The reoccurrences don't cost extra mana. Which means you can get 4 casts at 3 seals, worth 2.77 casts of damage for the mana price of 1.5 casts, because of the 150% mana cost multiplier, which can increases your damage per mana spend by 85%. The mana effectiveness increase is:

$\color [rgb]{0.6392156862745098,0.5529411764705883,0.42745098039215684}{\dfrac {{\text{casts per second}}+0.83}{{\text{casts per second}}*1.5}}={\dfrac {1+0.83*{\text{cast time}}}{1.5}}$

The mana effectiveness for any level is:

$\color [rgb]{0.6392156862745098,0.5529411764705883,0.42745098039215684}{\dfrac {1+{\dfrac {1-{\text{less damage}}}{\text{seal cooldown}}}*{\text{min(cast time, 3}}*{\text{seal cooldown}})}{1.5}}$

Getting passive casts from this support gem, that all unleash once you get time to cast could in theory be used to stack the dps of a low number of gems that have no cooldown and that one would normally continuously cast to kill an enemy.

Alternatively, instead of aiming for maximising dps, this support gem can be used with and other similar skills, which the player can use the stored seal to cast more SRS in one cast. Supported skills deal less damage when reoccuring tag only affects the spell part of SRS which deals no damage. Actual minion damage is not affected by the penalty during reoccuring.

It is currently intended that Unleash cannot support , as the skill can potentially have cooldown due to unique jewel.

Critical strikes are rolled once for all casts.
