  Hi,
  Some things will be more involved than others but yes you can. There are tons of resources out there to help you out. Here are a few to help you get started, the easiest place to start for a nwn newbie modder might be some videos:
  NWN Toolset Tutorial Videos
  NWN Scripting Tutorial Videos
  
  NWN University on the vault
  NWN Lexicon
  NWN wiki Scripting FAQ

  Yes, I was hoping for something a bit more specific.

  The script for premonition is in nw_s0_premo, you might start by trying to removing the visual effect eVis like so:
  

  //::///////////////////////////////////////////////
  //:: Premonition
  //:: NW_S0_Premo
  //:: Copyright (c) 2001 Bioware Corp.
  //:://////////////////////////////////////////////
  /*
      Gives the gives the creature touched 30/+5
      damage reduction.  This lasts for 1 hour per
      caster level or until 10 * Caster Level
      is dealt to the person.
  */

      if (!X2PreSpellCastCode())
      {
      // If code within the PreSpellCastHook (i.e. UMD) reports FALSE, do not run this spell
          return;
      }
  
      // End of Spell Cast Hook
  
      object oTarget = GetSpellTargetObject();
  
      //Declare major variables
      int nDuration = GetCasterLevel(OBJECT_SELF);
      int nLimit = nDuration * 10;
      int nMetaMagic = GetMetaMagicFeat();
      effect eStone = EffectDamageReduction(30, DAMAGE_POWER_PLUS_FIVE, nLimit);
      //////////////  effect eVis = EffectVisualEffect(VFX_DUR_PROT_PREMONITION);
      //Link the visual and the damage reduction effect
      //////////////  effect eLink = EffectLinkEffects(eStone, eVis);
      //Enter Metamagic conditions
      //Fire cast spell at event for the specified target
      SignalEvent(oTarget, EventSpellCastAt(OBJECT_SELF, SPELL_PREMONITION, FALSE));
      if (nMetaMagic == METAMAGIC_EXTEND)
      {
          nDuration = nDuration *2; //Duration is +100%
      }
  
      RemoveEffectsFromSpell(oTarget, SPELL_PREMONITION);
      //Apply the linked effect
  
      /////////// ApplyEffectToObject(DURATION_TYPE_TEMPORARY,   eVis,  oTarget, HoursToSeconds(nDuration));
      ApplyEffectToObject(DURATION_TYPE_TEMPORARY,   eStone, oTarget, HoursToSeconds(nDuration));
  
  }

  If I alter source NWN scripts - is there anything that I also need to do so that in an online (multiplayer) game - everyone gets the same spell modifications?
  
  Or is it enough to modify the spell effect source code in nw_s0_premo while editing my module?

  It's enough - Scripts are all run by the server so as long as the module has the edited script, the players will receive the edited effect.
  
  If you make more impactful changes, your players may also appreciate if you change the spell description to match with their new effects. That would require your clients to receive custom files (.2da and .tlk) so they could see the updated description.
