Jackie O'Callahan

Jackie O'Callahan is encountered in Generally Hospital zone only when you have the quest The Pack.

Background
Jackie O'Callahan, a.k.a. Father O'Callahan, was not one of Dr. Ned's test subjects. He was hired by Jakobs to help fight the evil. He apparently was 'nicked in the neck' when he fought Hank Reiss. His torso and legs are brown and his head and mane is greenish-black in color and he has a large cross tied to his back.

Involvement

 * Leave It To The Professionals
 * The Pack

Strategy
He has the usual boss attacks, slam, knockback, melee. He has a fair amount of health. He has the special ability to completely regenerate all health in a matter of seconds. His weakness is his open mouth when he roars. When he regenerates he grows larger and his claws turn red. He favors a leap attack. Actually he is much stronger than another rat-like boss, so beware about his strength and prepare well.

One proper strategy is to keep the battlefield fixed around the hut, where you can luckly find some skelerakk for second wind in case you have been defeated. Running in large circles would not do as the boss would chase your tail very quickly and use his leap attack to continue damaging you. Hence try dealing more damage than he could, and kill him before he kills you!

A good Maliwan Volcano can take out all four of them at range, without them reaching you.

Guaranteed Drops

Trivia

 * In the first of his ECHO recordings, his name is erroneously spelled "Father Jackie O'Cahallan".
