They have the same effect more or less. The difference is in how they are activated/applied. Overheat has a chance to become active if the opponent hits you. For Frenzy to become active you must hit the opponent. Shielding only blocks part of damage. You'll still lose health but the amount will be much less. Damage Absorption blocks incoming damage completly so you won't lose health at all.
