Dispelling a summon will not restore any mana by default
Summon Duration
The base summon duration for non-Necromancy summons is (2 Minutes + (8 Minutes * (Printed Spirit Speak Skill / 100)))
When players use the Spirit Speak skill to harvest energy from nearby corpses, it will automatically extend the Summon Duration of all their nearby non-Necromancy summons
Players can achieve a maximum summon duration of 30 minutes with Spirit Speak skill corpse harvesting
The amount of summon duration increase gained per corpse is determined based on the Creature Difficulty of the dead creatures and is further scaled based on how much damage the player did to the creature (as a percentage of the total damage dealt of all players)
Duration Increase in Seconds = (10% + (90% * Player Damage Dealt To Creature Percent)) * (50 * (Square Root of Creature Difficulty))
Berserk Summons
Blade Spirits and Energy Vortexes are considered "Berserk" followers and will automatically attack any non-tamed creatures/NPCs that are grey in their perception range
Berserk followers will not attack players or their followers
The player has no control over which creatures berserk followers attack, nor can they issue any commands to them
Berserk followers cannot be released but must instead be dispelled with the Dispel spell, either by targeting the summon directly or the player can target themself to dispel the lowest duration berserk follower under their control.
Berserk followers generate more aggro then other followers
Dispelling Other Players' Summons
When a player attempts to Dispel another player's summoned follower (with the Dispel or Mass Dispel spell) there is a (50% * (Controller's Printed Spirit Speak Skill / 100)) chance the Summoned Follower will ignore the dispel attempt (this applies to normal and Undead summons)
Stat and Skill Increases
The Stats and Skills of all summoned followers are increased based on the caster's Effective Spirit Speak Skill:
Stat / Skill
Increase
Hit Points
+150% * (Effective Spirit Speak Skill / 100)
Attack Speed
+25% * (Effective Spirit Speak Skill / 100)
Damage
+50% * (Effective Spirit Speak Skill / 100)
Wrestling
+50% * (Effective Spirit Speak Skill / 100)
Armor
+25 * (Effective Spirit Speak Skill / 100)
Magic Resist
+50 * (Effective Spirit Speak Skill / 100)
Dispel Resistance
20% * (Effective Spirit Speak Skill / 100)
Reducing Effective Spirit Speak
If a player gets PvP flagged their summons' stats and skills will be automatically adjusted to their printed spirit speak skill
Additionally Summoner Tome upgrades will not apply against players
If a player removes or deactivates any Aspect Armor or Mastery Chains that provides a bonus to their Effective Spirit Speak, any summons controlled by that player will have their summons' stats and skills adjusted accordingly
Players can further enhance their summoned followers against creatures with a Summoner's Tome which requires at least 80 Printed Spirit Speak and 80 Magery to use.
Any summon that is cast while the Necromancy "Vengeful Spirit" ability is active will be summoned as an undead summon with the same stats, skills and abilities as their normal counterparts.
