𝗔𝗿𝗴𝘂𝘀 Argi are Chaos Elemental mobs from Lycanites Mobs that appear when the balance of nature is out of control. 𝗦𝗽𝗮𝘄𝗻𝗶𝗻𝗴 --------- When enough Elementals in an area are killed (minimum three) in the Overworld, the natural chaotic energies will run wild and an Argus can spawn. The following chat messages will warn you of an Argus: You are disrupting the balance of nature, be careful! - Chaos Level 1. No negative effects will occur yet. Your destructive actions on the elements is drawing in Chaotic energy! - Chaos Level 2. An Argus will spawn soon if any more Elementals are slain. Balance seems to be restored... For now at least... - Resetting the Chaos Level. You have not killed any Elementals recently. Chaotic energy has manifested into something! Beware! - Chaos Level 3. A hostile Argus has spawned.

((Additionally, Argi (plural) can spawn in the End.))

𝗦𝘂𝗯𝘀𝗽𝗲𝗰𝗶𝗲𝘀 ---------- For every Argus that spawns, there is a 10% chance for it to be an Uncommon Subspecies. Uncommon Argi can be Scarlet or Dark. A Scarlet Argus is a bright red hue with blue eyes, while a Dark Argus is dark purple with green eyes. Uncommon Argi have double the Health of a regular Argus. This does not change their behavior.

𝗟𝗲𝘃𝗲𝗹𝘀 ------ Argi, like other mobs from Lycanites Mobs, can spawn at higher Levels. Local Area Difficulty can increase the Lvl of an Argus, and Argi spawned in Dungeons will also be higher Lvl than normal.

𝗕𝗲𝗵𝗮𝘃𝗶𝗼𝘂𝗿 ---------- A hostile Argus will fly around the player, attacking them from a distance. While attacking, they will glow the color of their eyes while trying to throw Chaos Orbs at the player. The orbs will send the target flying randomly in any direction (caused by the Instability effect). Argi are fast and attack quickly, and their high damage makes them a dangerous threat. Caution should be taken when trying to defend from one.

𝗙𝘂𝘀𝗶𝗼𝗻 ------- Argi will fuse with other nearby base elementals to form stronger ones. Aegis, Cinder, Djinn, Geonach, and Jengu elementals can fuse to form a Lvl 20 mob of the respective type. If both elementals are Uncommon, the resulting elemental will also be Uncommon. The following is a full list of results when a mob is combined with an Argus:
