Summon Raging Spirit

Summon Raging Spirit (commonly referred to as SRS) is a minion spell that temporarily summons a flying flaming skull that charges at enemies and attacks them.

Skill functions and interactions

 * Attack Modifier: There is a hidden attack modifier that is applied. It is currently unknown whether it is a Local Modifier or a Global (more? increase?) Modifier.  If Local, then it only applies to the base damage.  If Global, that applies to all added and converted damage as well.


 * Added Damage Modifier: There is a 15% penalty to added damage on the Raging Spirits.  It does not apply to damage that are  (unconfirmed).  In practical terms, gems like  or  are affected by this penalty, while  is not.


 * Damage conversion:, similar to the bonus on Infernal Blow.


 * Targeting: Raging Spirits cannot be targeted directly by enemies. However, they may be damaged by stray projectiles and area of effect skills.

Damage auras

 * A level 20 grants 33 additional average fire damage to Raging Spirits.
 * A level 20 grants 36% of physical damage as added cold damage.
 * A level 20 grants 40 additional average lightning damage to Raging Spirits.

Assuming similar resistances, Hatred will provide significantly higher damage to Raging Spirits as it is not affected by the 30% effectiveness of added damage penalty.

Support gems
(all calculations below assuming level 20 gems) From Modifiers, the multiples come after damage conversion, so for a Raging Spirit in a Hatred aura, it is doing 50% Physical, 50% Fire, and 36% Cold (percentages are off of the base Spirit) Assuming you have all Minion Damage nodes, you have 105% increased minion damage, for a basic damage of 278% of base roll.


 * gives 49% more damage (no type limitations) and so would result in a damage of 415% of base. (Pre 2.0, Minion Damage gave increased damage, which is added to the 105% for a damage of 345%.)
 * gives 49% more physical damage. Since SRS damage is 100% Physical converted to 50% Physical and 50% Fire this bonus applies according to Damage conversion rules.
 * does not affect single target damage but gives 31% less damage to nearby targets.
 * has become more beneficial to make up for the clear speed reduction of only having 20 spirits (down from 50, as of Patch 2.5.0).
 * gives +40 base damage at level 20 and 21, +50 at level 22 and 23, etc, which translates to a ~10% exponential base damage per level of empower. Level 2 Empower is weaker than Melee Splash and Melee Physical Damage.  Level 3 Empower is weaker than Added Fire Damage.  Level 4+ Empower is better than everything.
 * boosts the base fire damage of the spirits as well as damage from the Hatred aura and Added Fire Damage Support.
 * occurs during type conversion, and adds 44% of the base roll as extra Fire damage, which turns out to be 369% of base roll.
 * gives 94% more attack speed for 30% less damage, which is all multiplicative, for roughly a 36% damage increase, (1+0.94)*0.7 for a damage factor of 377% of base roll.

+2 Minions, +2 Melee, or +2 Fire (for item mods?) - +2 Melee Gems will affect many support gems that are linked to SRS, but do not boost SRS directly, making it an inferior option. +2 Fire Gems will boost SRS and Added Fire; this mod is usually found in weapons such as wands, staves or other essence crafted weapons. +2 Minion Gems will boost SRS and Minion Damage/Minion Speed and is typically found only on helmets. Depending on whether you are using a 5L or 6L 2-handed weapon or the helmet for endgame, look for the appropriate mod to boost your damage.

In order of preference:
 * for clearing maps faster.
 * for bossing, for clearing.
 * for some additional elemental damage.
 * is still powerful when combined with other sources of elemental damage, but alone is only half as effective as other supports.
 * provides occasional bursts of power, but is generally less consistent than other supports due to only boosting every third hit.
 * depending on level, but since it takes so long to level, it's probably the last one on your 6 link anyways.

AI
Raging Spirits don't behave like zombies or spectres, but they pick their targets independently of your actions (attacking usually the nearest targets while zombies focus their attack where you attack). It can be useful to help other minions focus their attacks on enemies near you instead of enemies somewhere far away because they'll prefer attacking enemies that the spirits are attacking.

As of Patch 2.1.0, Raging Spirits tend to concentrate less on one target, except in cases where there is only one target or for targets close to the caster (see Version History at the bottom of the page).

Maximum spirits
The attributes that will improve max spirit count are Cast Speed and Skill Duration.

$\begin{align} D & \text{ percent increased Duration } \\ C & \text{ percent increased Cast Speed } \\ E & \text{ percent More Cast Speed } \\ \end{align}$

Assuming that you continuously cast Summon Raging Spirits, then the formula for how many spirits are on the screen at a time is:

$5.0 * ( 1 + {D \over 100} ) \over { 0.5 \over { ( 1 + {C \over 100} ) * ( 1 + {E \over 100} ) } }$

which simplifies to:

$10.0 * ( 1 + {D \over 100} ) * ( 1 + {C \over 100} ) * ( 1 + {E \over 100} )$

and round up to get the maximum number of spirits reached (with a mximum of 20).

Example calculation: If you have 45% increased skill duration, 76% increased cast speed, and 70% more cast speed, you would have $10 * 1.45 * 1.76 * 1.70 = 43.384 > 20$, which means that if you continuously cast, your spirits will despawn earlier than necessary. This means you can spend several seconds per cycle on other things such as dodging, casting curses, or moving in between spirit castings.

Formula for (30% reduced cast speed, Spell Echo's More Cast Speed doesn't apply): $7.0 * ( 1 + {D \over 100} ) * ( 1 + {C \over 100} )$

Version history

 * Mana Cost at gem level 20 is now 16 (was 12).
 * Raging Spirits, Raised Zombies, 'of the Grave' enchantment minions, and Spectral Spirits (from Essence of Insanity on a weapon) now have 100% more base accuracy rating than previously. Raging Spirits mana cost changes have been undone.


 * now have a 15% less Added Damage multiplier, up from 30%.
 * Raging Spirits, Spiders created from Arakaali's Fang, and the spirit skulls from the can no longer taunt their enemies.


 * Reduced the maximum number of Summoned Raging Spirits to 20, but we have also increased damage as the gem levels up to compensate. It's intended to be a similar damage output but with less casting needed and less effective area of effect.
 * Totems and all other minions now have 40% elemental resistance and 20% chaos resistance. This also includes minions that didn't have resistances previously, like wolves.


 * Summon Raging Spirit's duration has been increased from 3.5 seconds to 5 seconds. The mana cost has been reduced from 6 to 5 at level one and reduced from 15 to 12 at level 20. The cast speed has been reduced to 500ms from 800ms. The damage dealt by Raging Spirits has been substantially reworked and is lower at high levels. Raging Spirits are now more likely to target enemies who are attacked by fewer Raging Spirits, except when enemies are close to the caster.


 * Raging Spirits have had their damage reduced at higher levels. There's no change at gem level 9, scaling to 8% less damage at level 20 of the gem.


 * The damage done by the summoned Raging Spirits has been reduced at higher levels, up to a 20% reduction in damage at level 20.


 * The damage has been increased at higher levels up to 66% more damage at gem level 20.


 * Summon Raging Spirit has been added to the game.
