Alex is exceptionally difficult to kill or exceptionally time-consuming to kill if you throw Sacreds on him and his passive isn't disabled at battle start. Takes a multi-turn character to get a couple turns in order to kill him. With Orbits, Alex is a 1-hit kill from Van Helsing or a few others. Orbits aren't great for defense unless you face only true damage dealers. Orbits on W LOL work so well due to the counter/revenge strikes of W LOL's passive. They work well on Cosmic/Gunner LOL too only not to the same degree as W LOL.
