[If your unit almost died you can retreat it for recycled points]
for those who weren't prepared for the game
the trick for rerolling is
Play the game until map 01 ---->surrender to avoid wasting time then proceed to claim gift and gacha
if you don't like the guaranteed 6 star just overwrite
By clear arknights Data then proceed to Google settings--->ads--->reset advertising ID
THE good 6 star are (silver ash ,siege and Exusiai).
After getting the above don't claim you pre reg 5 star ticket yet.
do a 10x roll first for something that you want so your early team spread out better.
Because the game punish you for stacking level on one unit and having too much of the same attribute so better make your team diverse so you don't get hardlock at the start
Then for the pre register 5 star
It offer you 4 operator which is
Red project (spamable redeployment=good bait fodder)
Silence (fast healer and can accelerate other healer )
Pramanix (high Dmg magic in general)
Pick one that you lack after doing the 10x pull because everyone on the list is good T1
Anyway Goodluck on the search and happy hunting
P.S game better than girl front line
