Taclaks were once a mischievous tribal people that lived in the Aman'lu forest outside of the Elves' hometown. Decaying Bound Taclaks bear little resemblance to the Taclaks the Elves knew. They are afflicted with some disease, and though it gives them frenetic strength, their bodies are poisoned and falling apart. They are barely held together by the bandages that cover them.
However, the greatest danger is not from their strength or mindless brutality. When they're killed, their rotten blood spills out in a toxic cloud that poisons and dissolves everything it touches. Entire towns have been destroyed when a brave defender struck down a decaying Taclak, spilling its deadly blood over himself and his companions, and dooming them all.
