An Invasion is a GM(Game Master) run event. The GM's spawn mass quantities of Giant and captain mobs from all over Madrigal. All mobs will be red named (aggro) and will attack on sight. Monsters that are included in the spawn are not limited to Forsaken Tower Secret Room Giants such as Asmodan. They will also spawn mobs from the cash-shop locations Coral Island and Azria, and they will be aggro. Many mobs that the GM's spawn are special mobs that you will never see else where, listed here:Event Spawned.
The GM's also like to pretend sometimes that 2 of the 3 Roika gods will apear. Shade, the goddess of anger and hatred is who "causes" the invasions as she can control all beasts. Bubble, the God of happiness can't do anything about the monsters, but he might hand out long-lasting buffs. The only god usually not in attendant during these times is Ibliss simply because he is the god of indifference, and doesn't care about anything.
Things to note: The Blue and Green Meteonykers do not have drop tables, and have much more HP than the Red Meteonyker but do NOT have the Red Meteo's call-out attack or the fire aoe.
Clockworks is the only mob, out side of server Yetti, that will not give you the 'Cannot fight against a monster somone else is fighting" warning. The drops can be picked up by anyone.
GM Cromiell is just the real GM Cromiell in a Clockworks mob-trans. He has 10x's the HP as the regular Clockworks has and may be even worse than the actual Clockworks because he can TALK to you. GM Cromiell does not have a drop table either and will not drop CW gear.
Do not attempt to fly around Asmodan, Drakul the Diabolic, Dread Drakul the Diabolic, or (Deathbringer) Kheldor as they will send you hurtling to who knows where.
The Towns may not be the safest place to be, as people often use the yoyo skill Pulling to drag Clockworks into town. Clockwork's aoe skill is indiscriminate and will kill even afk shop keepers and collectors. Thinking of raising a pet on Invasion day? Don't do it on the invasion server! (Invasions are normally held on the last channel of servers, or on ch 2)
