So far since invasions were unlocked i am doing them daily till i have 0 deathmarks with wins and loses. So far i did a total of 90 to 110 runs (as i do not know the 100% exact number) it just does not seem to RNG drop. It is insane that it has not dropped yet after so many matches regardless of win or loss. But based on luck I hear others say they got it in their first match or between 1 to 10 matches. Meanwhile im being blown up to pieces by at-st overpowering me for 50% of the time in the hope of getting it soon. Jts very stressfull for me as i mostly play PVE and barely PVP. And yet i really want to have the red crystal. So im venting my stress and questioning the activity to even have more drop chance for it as 100+ runs is insane even if i am unlucky. (I still will try to do more invasions to try and get it. Wish me luck i guess
