very simple, first of all remember that Fitl to blind both kulle and SB or mainly for SB so he wont catch u. What u need to do is kill Kulle first, the only way is to use FOT run and dash to hit kulle, on ur Sw and wack kulle, when SB is too near, pop Fitl or Bell to stun him, and run around. How i kill kulle is slow but i run around alot, wait for my FiTl to be ready and FOT to kulle pop SW, hit hit hit and den pop Fitl when SB come closer.  Yeah the buble is slow but run out of it, alot of running. and if u get Too close to SB run around or away from him. this the only way i i can kill kulle first then SB, slow and steady can kill one.

yeah i find sb and kulle the hardest when solo Uber. but thats how i manage to kill them. if i aim SB, there are chances, that kulle bubble and stone/fireball me together with the fact that sb will SLAM me me, catch me and gg. Eventho my gears have greatly improve, i still do the hit and run tactic, coz its easier and i dont have to face SB until kulle is dead..
oh and another thing, add us up, we help u uber ( i can do low uber LOL) and yeah its easier and can do many more ubers. + faster Klawo#6490 if there anything i can help (still noob, dont trust what ppl say, i noob one)
