Ciao Akeisha :p
In Irdrich there are 3 kind of mobs one near the other around Tequatl (as Allods-Online-Player said).
- Rusty Golems (magical creature)
- A lot of animals like monkey, parrots, tigers, crocodiles, etc (beasts)
- Undead (Impassible Wilderness, on the right side of the map. U can take the "alternative reality" teleport to go there from Tequatl)
The only one kind not present in Indrich, as far as I know, are the demons, like other said above me.
The easiest are those of 55-56 in the left part of Umoir Lower City, in the starting quests area when u arrive in the map.
The malus in going to Irdrich is there is no drop to sell to gain some gold in the meanwhile. The bonus is speeding up the quest because of the easy kill of 53-54lv mobs.
