I have 8k cps, need 18 frags of Shisui, and i certainly wont spend it there. Its too much RNG, and i think drop rate for him is very low, so i would pass it if i was u. And btw, since his frags still worths more than 100cps/piece, i wouldnt do it on your place - just stack this week. Who knows, he can come maybe in next lucky board. *fingers crossed*
