Acid demons were formidable as close-range opponents, utilizing a range of powerful chops and a devastating Double Chop attack, while at long ranges they expelled a powerful stream of acid. Acid demons were proficient at blocking attacks and defensive manoeuvres but were vulnerable to sidestepping counters and mixed combinations and low strikes[Soul Reaver 2 strategy guide (Prima)]. Like all the demons Raziel fought in Soul Reaver 2, Acid demons could follow him into the spectral realm and could also create combat barriers to prevent Raziel from escaping[Soul Reaver 2 manual][Soul Reaver 2 strategy guide (Prima)].
Raziel first encountered Acid demons in the Demon-infested Sarafan Stronghold shortly after he emerged from its Time-streaming chamber in the Era following Blood Omen. They would frequently be encountered throughout that era, particularly in the Swamp, Subterranean Pillars chambers and Mountains[Soul Reaver 2]. When Raziel continued his quest into Nosgoth's early history, Acid demons were among the Demon enemies that appeared (apparently 'transported' from the Post-Blood Omen era) and confronted Raziel as he attempted to return to the Sarafan Stronghold; again they confronted him in the Mountains and Subterranean Pillars Chambers[Soul Reaver 2].
- Acid Demons are referred to as "demonba" in game files[Soul Reaver 2].
- Many demons variants in Soul Reaver 2 share similarities with their Blood Omen counterparts; Acid demons notably have a similar color and similar toxic attack to the Ogres seen in Blood Omen: Legacy of Kain[Blood Omen]; though it is unclear if the Soul Reaver 2 demons were intended as re-interpretations of Blood Omen's demons or simply different demon races. Acid Demons also share a similar attack to the green Lesser demons of Blood Omen 2 and have blade arms like the Hylden warriors and Shield guardian of Blood Omen 2[Blood Omen 2].
- Acid demons are the only Demon variant in Soul Reaver 2 that does not openly taunt Raziel upon their appearance in Nosgoth's early history[Soul Reaver 2].
- Acid demons, like other demon enemies, are presumably native to the Demon Realm and affiliated with the Hylden.
