Cyclops reduces damage by 75% (When HP is full) so be careful when 2 or more enemies hit you at once. (Take one of these out with your shooters).
Active ability 30,000 damage to all, which can be very useful !!
Tip when using Cyclops. Not sure this is 100%, but I don't think the same cards change their CD timers, thus if your facing 2 succys and one starts on a cd3 and 1 on a cd5, they'll never hit you together. So as long as you can heal between the spins worry about taking something else out.
i.e. a skeleton has a CD4 sooner or later that will align with one of the succys.
If Cyclops allows you to survive (Even a big hit) take out one of the easy kills with your shooters. (It doesn't always need to be the big hitter, just stop 2 hitting you at once)
