Your Hits can only Kill Frozen EnemiesFar south, the winter crawls under the skin.
Below the snow, adrift wanderers sleep. gloves have the potential to prevent your hits from killing enemies, keeping them alive on 1 life. This allows the character to wait until the soul gain prevention time is over to kill enemies and gain all souls from all kills. The base duration is 1 second and this can be reduced further by Vaal Skills have % reduced Soul Gain Prevention Duration. After the soul gain prevention timer has expired, the enemy can be killed by any non-vaal skill that can do damage over time and the character will gain all souls for all kills if they have room to store those kills. If the kill size outnumbers the souls per use in every situation, this combination can be repeated over and over again. In other words in areas where you regularly kill 15 enemies or more at the same time, vaal ground slam will always have enough souls to be used on every pack of enemies.
