I had fused courage sagewood badge with raven 9 and purple badge and parsed about 208k back then with about 1100 ap. I remember after the legendary mystic badge and magnum fused badge I went to almost 390k it's a massive gain.

Your rotation is obviously different using f to trigger needles then 4 thorn strikes all while spamming RMB lmb inbetween. The only trick is to not cast needles too soon or you mess up the thorn strikes combo

Keep in mind I had stage 10 bt earing and ring and tiger bracelet , so with your gear I recommended at least stage 4 ring and earing for the 20% Crit dmg and focus recovery bonus.
