Perk

Type: PERK
Papyrus: Perk Script, Perk Fragments

Perks are abilities applied to Actors in a similar manner as Spells. The player will encounter these as they gain levels and play through the game. If a Perk has more than one allowable rank, then the player may increase its rank instead of picking a new Perk. Increasing a Perks rank will typically improve its effectiveness.

Perk Entry Dialog

Perk Entries define what happens when the player has the Perk. A perk can either apply all its entry points at once or leverage the entry point ranking system.

• Rank: The rank indicates when the entry point should run. Each time a perk is added to an Actor the perk's rank will increase. If an entry is applicable at multiple ranks, it must be specified for each rank.
• Priority: Controls the precedence for this object. Used to control order of operations when the two perk entries affect the same value. Valid range is 0 to 255, with lower values indicating higher priority. A perk entry with a lower numbered priority will take precedence over one with a higher numbered priority.

  • Function: How the Entry Point is affected: plus, minus, multiply, set, etc.
  • Function Data: Text, script, or numeric data used when applying the entry point.
• Conditions: The Conditions must be met. For example, a condition here allows you to specify that the perk only functions if the player's health is below 50%, or only works if they have a specific weapon equipped.
  • Perk Owner: The conditions are evaluated against the perks owner.
  • Weapon: The conditions are evaluated against the perk owner's equipped Weapon.
  • Target: The conditions are evaluated against the perk target.

Entry Points

These are the Perk Entry Points used by human Actors.

Entry Point	Description
Activate	Adds a new choice to show in addition to the normal activation prompt Button Label: The button text for the new choice. Run Immediately: If checked, there is no selection menu.

Apply Bashing Spell	Applies a spell to the target when the perk owner successfully bashes him/her (with a shield or weapon). Does not appear to work in Fallout 4, and is not used by any vanilla perks. As of Skyrim, the spell archetype must be Fire and Forget - Contact, Constant Effect - Contact, or Constant Effect - Self
Apply Bloody Mess Spell	Applies a spell (to whom?) when the perk owner successfully triggers the Bloody Mess effect upon killing an enemy.
Apply Combat Hit Spell	Applies a spell to the target when the perk owner successfully hits him/her in combat. In a change from Skyrim, bullets count as hits for the purpose of this entry point.

Alternatively, a perk can modify the chance for all chems, as seen in "PA_BloodCleanser".
