at one point at a +5 (10's,30's) emp staff like 184m.atk 12% int 3line epic
hammered twice
was planning to farm more tempest coins to finish off the staff
I saw I had a 2star ee and 2 AEE's. I decided I'd use the 2star ee because it is 80% chance to work and 50% explosion if failed compared to the 90% pass 100% explosion to fail. Didn't have a protection scroll so I decided I'd use the 2star ee.
boom
so my self scrolled godly emp staff is destroyed which took 4 prot scrolls 8 lucky scrolls and over 200+ tempest coins
Still had ~900mil left so I decide i'd do it again but with 40%'s on an emp wand.
first scroll fails, second works, 3rd scroll destroys it....
dat luck
so i bought a clean emp wand tried three 10's on it all failed

terrible day
however, my emp hat is 6% int 8m.atk 38 int(?). so not too bad I guess
tldr;
farms coins, sell helisium capes,tempest gear. scroll perfect weapons with tempest eventI started with 0mesos (not even kidding)
sold tempest gear at fm
bought decently scrolled weapons
perfect scrolled them
sold for ~700mil each
funded my i/l mage
tempest event is definitely one of my favorite events of recent memory
