Scarlet Tulip is really nice against raid bosses. Teamed with girl with similar abilities (Cyrtanthus for example), you can achieve indecent amount of damages. Even she is useless in missions, I use mine in my one and only team for raid boss and she a really nice job for a lvl 24 evolved girl. It's also really funny to get a Kerria with more than +100% damage boost doing a 38k damage healing skill. And anyway, it's always better than +1 canon node target.

I'm not sure but I think I've heard of really powerful raid bosses in the future. Not sure if it's true or not but if it is, boost like that will be useful.
