New Update!
there should be 100 jewels as an apology in your presents box, so be sure to claim it.
old cards can be awakened (such as HSR High Vampire from the regular summons.)
they added Legendary Archwitches which are pretty... end-game.
they have 100 million health (minions with 1 million health)
can only be found at a low chance by archwitches.
deal massive damage
you can bypass damage cap
automatically sends to your alliance only for assistance(can't help you guys here).
doesn't drop itself but high chance for other goodies.
*first off, sorry for a little mistake i made*
anyways, they're decent turn stallers... and they're pretty cute dogs. be careful though, they only proc once.
I try to discourage players from using micro-transactions. the game can be pretty fun as a free player. it just takes a little longer. well, that's my bias anyways.
By 'pull' i'm assuming you mean drop rates? URs are pretty true to their names with a ~1% drop rate on summons. i don't know the drop rate for battle rewards, but i think it's safe to assume something similar. SRs i believe are ~15% from summons and, again, i don't know for drops but i think it's similar.
