A quick way to dispose a Drowsy Ochu is to use Fire-elemental spells and Flametongue. Using Light Curtains helps mitigate the damage it can do with its physical attack. Equipping Lightning-resistant equipment helps neutralize its Thundara and Thundaga spells, while having Poison-resistant abilities nullifies its Poison abilities.
[view·edit·purge]"Ochu" comes from Dungeons & Dragons; specifically, it is the otyugh. The name in Japanese (and transliterations) comes from the pronunciation; it is pronounced with a short O and T (practically to a ch), making the pronunciation close to "o-chuugh". "オチュー" is the closest the katakana system can get to representing the sound without using compound katakana pronunciations not natively found in Japanese.
