Incorporeal Movement. Kachada can move through other creatures and objects as if they were difficult terrain. It takes 5 (1d10) force damage if it ends its turn inside an object.

Innate Spellcasting. The Kachada's spellcasting ability is Charisma (spell save DC 17). Kachada can innately cast the following spells, requiring only verbal components:

At will: detect evil and good

1/day each: commune, raise dead

3/day each: 

Magic Resistance. Kachada has advantage on saving throws against spells and other magical effects.

Summon Lare. once per day, Kachada can summon 1 Lare.

Possession (Recharge 6). One humanoid that Kachada can see within 5 feet of it must succeed on a DC 17 Charisma saving throw or be possessed by Kachada; Kachada then disappears, and the target is incapacitated and loses control of its body. Kachada now controls the body but doesn't deprive the target of awareness. Kachada can't be targeted by any attack, spell, or other effect, except ones that turn undead, and it retains its alignment, Intelligence, Wisdom, Charisma, and immunity to being charmed and frightened. It otherwise uses the possessed target's statistics, but doesn't gain access to the target's knowledge, class features, or proficiencies.

Interception. If a creature within 30 feet of Kachada is the target of an attack, Kachada can move between (or to the closest space) to take the damage instead.
