Tainted Blood Pendant

The Tainted Blood Pendant is an accesory 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) each 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: $$\left \lceil ( 2.5 \times Cost ) \div ( Duration \times Level ) \right \rceil$$

where the cost is the crafting cost of the brew in a vial, duration is its duration in ticks, and level is the effect's level.

For example, the pendant infused with Haste II costs (2.5*4000)/(1800*2) = 3 Mana per tick.
