If someone from level 3 to lvl 126 attacks me with a magic spell while im killing a spectral: no matter what level he is, the spectral will go away and ill have to start again.
Example: your lvl 60 and ranging the spectral. Now some 126 comes and thinkx your his level, doesnt think nd just casts barrage on you. The spectral will go away nd you will have to start again.
