Tainted Blood Pendant

The Tainted Blood Pendant is a bauble added by Botania. When worn in the Baubles Amulet slot, the player will be given the potion effect infused into the pendant for the duration of 4 seconds (14 seconds for Night Vision) every 4 seconds.

Infusing the pendant with a brew requires putting it in a Botanical Brewery with all the brew ingredients. The infusion takes 10 times as much Mana as brewing a vial with the same potion. Brews of Instant Health, Absorption, Absolution and Overload cannot be infused.

The pendant's Mana cost per tick is calculated as follows: $$Cost=\left \lceil ( 2.5 \times Cost_{vial} ) \div ( Duration \times Level ) \right \rceil$$

where $$Cost$$ is the Pendant's cost per tick, $$Cost_{vial}$$ is the crafting cost of the brew in a vial, $$Duration$$is its duration in ticks, and $$Level$$ is the effect's level. This value is rounded up to the next integer.

For example, the pendant infused with Haste II costs $$(2.5\times4000)\div(1800\times2) = 3$$ Mana per tick.
