As with other boss pet items, this item follows the drop threshold system. However, unlike other boss pets which follow this system, it has two distinctly different drop rates: * When Telos is defeated at an enrage level of 99% or lower, Telos' tendril is received at a drop rate of 1/1,400 (2x more uncommon than the base drop rate). * When Telos is defeated at an enrage level of 100% or greater, Telos' tendril is received at a base drop rate of 1/700. Regardless, both drop rates share the same threshold of 300 kills.
