The emissive is set at a moderate value, but tweaking its intensity is extremely simple. You can also modify the timer.

Altering Emissive

1. Export character/nh/nh00/script/nh00_initialize.ebex and open the file on Notepad++.
2. Alter the glow intensity by increasing/decreasing the </fValue_> on objectIndex="834":

      <r_ type="float">1</r_>
      <g_ type="float">0</g_>
      <b_ type="float">0</b_>
      <a_ type="float">1</a_>
      **<fValue_ type="float">0.3</fValue_>**
      <iValue_ type="int">0</iValue_>
      <bValue_ type="bool">False</bValue_>

Altering Countdown

1. Repeat the step above.
2. Alter the countdown by increasing/decreasing the </time_> value on objectIndex="837":

      <delayType_ value="1" type="enum">DT_TIME</delayType_>
      **<time_ type="float">80</time_>**
      <isRandom_ type="bool">False</isRandom_>
      <randomMin_ type="float">1</randomMin_>
      <randomMax_ type="float">2</randomMax_>
      <forceAtPause_ type="bool">False</forceAtPause_>
      <forceFrameCount_ type="bool">False</forceFrameCount_>
