Re: Heir to the dark side Tier 6 issue
@blakviper1999 1000 siphon is a lot. I'm pretty sure I was never over 300/400 siphon when I did the event.
This sounds like you aren't using SLKR's second special enough, and are using the middle move too often. Siphon is not doing anything if you don't use the second special (Furious Onslaught) to drain Mastery from the opponent. Good move order is event ability > first special > second special > repeat
What's your full team? Too much TM gain on your part will ramp up her Mastery too.
Edit: just did a quick run and all seems to be as usual. Full team SLKR, Hux, FOST, Sith Trooper, KRU.
