[Doom] DECORATE practice - Lightning Imp (Fixed)

As result of some experiments, I found a fact that the 'puff' is responsible for damage type of bullet and railgun attacks. So, I managed to prevent my Lightning Imp from getting damage from his own lightning bolts.
(Failed version: • [DOOM] DECORATE practi... )
And I added an attack pattern to Lightning Imp. When he tries to blink, if Player is in close distance, Lightning Imp rushes towards player instead of running pointlessly. When Lightning Imp rushes, it drops some 'delayed' lightning core on its pass, and they explode after the Imp ends rushing.
Now Lightning Imp is focused on 'appealing', so he is not so strong(difficult) enemy in-game. But, I expect he will be so threatening opponent when fight in narrow arena instead of big-big courtyard.
