Tree Of Savior - Trying out Eskrimer Swordy Class in Joint Strike

Just got the new class ... haven't touched swordy for a while ... just spam and repeat till the 3rd tier skill "Pasato Solo" pops up from 15 stacks ... need to use the channeling buff "Invitation" before it for 20% more final damage .... wish it was insta cast than channeling ...
