Cassiopeia ideas.
change twin fangs to reapply poison so dont have the pressure of time before poison runs out** and** spacing from your victims.
make it so as long as an enemy is poisoned you gain the movespeed from noxious blast to give her some more mobility.
other compensations might need to be made in addition but im mostly throwin these ideas out there cus there was talks of buffing cass in terms of how she does her damage. do with this what you will.
