Marchenko casts TITAN Shield whenever he takes lightning damage, granting him physical and magical damage immunity for one turn. Attacking with lightning damage will maintain the shield each turn, so do not use lightning moves on the next round to get rid of it.
Marchenko cannot be pushed past 49% HP in a single turn.
If you deal lightning damage, he will cleanse all breaks you apply with TITAN Shield, the turn after. So apply the breaks when you need them to not waste any turns.
If you use the Kill Switch strategy, you WILL NOT get the "Kill with LB" achievement.
Bring a provoke evade tank and a 100% fire + thunder resist magic tank, and also a MP regen character.
