📋 About This Mod

Adds a magic effect making use of the base game script "LegendaryOnHitCrippleScript" that instead gives the Mesmetron attack a 50% chance to cripple PerceptionCondition (Head). There is another main file that also adds other special effects

One main file just adds a Magic Effect, DLC01_modCustomEffect_Mesmetron, that makes the Mesmsetron have a 50% chance to cripple the head (PerceptionCondition . The magic effect is applied to DLC01EnchWeapRobobrainGhostFlash (XX01106F).

The other main file also adds the Magic Effect that can cripple. It also adds some other affects that can occur:

  • []DLC01Bot_Unstable_FrenzyEffect "DLC01Bot_Unstable_FrenzyEffect"  set to duration 60 with a 30% chance to occur.

    []DLC01Bot_Unstable_ExplodeHeadEffect "DLC01Bot_Unstable_ExplodeHeadEffect" with a 20% chance to occur.

    []ParalyzeEffect "Paralyze"  set to a duration of 3 with a 50% chance to occur.

    There are also two optional files that increase the damage that the Mesmetron attack does by increasing the "Damage - Base" from 24 to 75, and increases the "dtEnergy " from 24 to 75 as well.

    NOTES:

    • []With the "Cyclops Helm" equipped, the total damage it does is increased to 300 total (150 from "Damage - Base" and 150 from "dtEnergy "

      []This WILL effect the damage that enemy robobrains do with this attack as well.

    COMPATIBILITY:

    • []This WILL affect custom robobrains as long as they use "DLC01BotWeapRobobrainMesmetronHead" (XX0087BB)

      []If a mod like SCOURGE is enabled, then the damage increase won't matter to enemy robobrains.

      []Has a patch for Automatron Expanded Weapons System that also includes the damage increases to it's custom Mesmetron weapon, "DLC01BotWeapRobobrainMesmetronHeadSeeker" (XX001F19).

    • This mod is incompatible with any mod that also edits DLC01EnchWeapRobobrainGhostFlash (XX01106F)
