Rage Focus is an item property found on weapons that causes the damage inflicted to start off below -40% of the weapon's base damage but steadily rises until it is +20%. I can surpass the 300% damage cap. In effect, initial damage is lower than normal, but eventually reaches a point where the attacks are higher than otherwise possible before the cycle ends and then begins to repeat.
Overall, the effect of the property is to give more cumulative damage when used than when not, with less damage initially and then more damage conclusively.
