Yea the hard part would be to implement it into a PVP build. The talismans wont really help much in PVE since you can mostly 1 round stages. To me this is one of the best 4* event characters to come out. Even if some are seeing low drop rates, everyone should be able to acquire one bat. You now have a multi-hitter on par with some of the Lilliths with some added heal and a passive.
