Is Shadow Aspect glitched? (minor spoilers)
In Old Bhaal's Temple, in the secret place, when i face shadow aspect he appears to be 100% invisible all the times, for a fraction of seconds, maybe 0.1s, i see him in the immediate moment he hit's me, then he vanish. True Sight apparently doesn't work on him, the same for any other means of invisible detection.
Thus far, the only choice i had in my playthroughts was to send an iron/stoneskin character, pause in the fraction of seconds he appears and ctrl+Y him.
