Rin yes as she is the fastest unit and hits extremely hard. Karma well depends. I am still using Ace and Teo instead of karma since mine's only 30

50% additional damage ain't that great especially if the enemy have Rudy. Still need Ace to balance those rudy. Teo is for sustainability if his zombie don't get debuff. WK has better sustainability but is easily killed early on in the current rin/karma meta making him useless.

I need a guild . Just Lv 12

I will recommend transcending rin to 32 as you can equip jewels on her rather than a 30 teo.

And yes, all the special heroes including the 7k are rare and hard to get. You'll be lucky if you can get them to 40 within a few months. As for me I took more than 7 months of gameplay just to get my Ace to 40.

Also funny to see bugs that happen in the replays. Like seeing jave resurrected himself out of no where then deal damage which later causes the whole match to hang.

Synthesize a pascal. But no more fina to level him up.

celestial tower, normal adventure runs ( I still havent complete them  ) etc ... he's so tou fu...

Pascal is a must have for arena. I foresee all those top players changing DQ to pascal now. All should have same team of Rin, Karma, Teo, Spike, Pascal. Lol

I also have Pascal, still thinking to Fina him or not
because Pascal dont give a shit to Spike's block

Haha. I already fed all my Fina to Pascal. Now he's 36 but I don't have any HP armor and SPD weapon to give him. 

The problem is, I can't find any SPD magic weapon on my heroes! 
At the moment, I just keep doing raid and random craft hoping to get a SPD weapon soon.

I am at 72 and no rin.  I will just pick rin but don't do extra pull while waiting for karma board.

50 no right to complain yet.
