Great Ice Golem
To use the portal from Penumbra to Inferno you need the correct ring
Here is a list of NPC's you will speak to throughout the quest
Here are a list of items you will need for the quest
The quest starts in Adonis Catacombs, you will need to find A Page From The Yomi Grimoire. These can be looted from Yomi Grimoire himself or any of the other bosses in here, unless you are very high level the catacombs are not a place to solo, so bring a few friends
Once you have the page head up to Penumbra, the easiest route is to use your key on a transit statue. You need to speak to the Sipius in the Redeemed Temple, he can be found upstairs in the northern room. Give him the page in return for The Book of Insignificant Rituals
Take the book to the Ecclisiast in the same room, he will use it to summon forth Redeemed Cama. Speak to Cama who will hand you the Sealed instructions to Acolyte Cama Hume
You now need to travel to the Unredeemed temple, in one of the side rooms you will find the Patriarch Prophet Nar Van. Kill him to spawn the Acolyte Cama Hume, don't forget to loot the Sacred Blueprint from him. Speak to the Acolyte and hand him both the Sacred Blueprint and the Sealed instructions, he will now summon Vanya for you
To kill Vanya you will need a decent team as it hits quite hard, once you have loot Vanya's Beating Heart.
Note: You now have only 90 minutes to complete the next task
Head back to the Redeemed Temple and speak to the Ecclisiast, let him see the Beating Heart and he will summon Redeemed Cama for you again. Speak to Cama and hand her the heart, in return she will give you the Complete Blueprint Pattern of 'The Great Ice Golem'
See our Pocket Boss Guide for detailed instructions on how to assemble a Pocket Boss, once it is complete it can be spawned at the Incarnator in Penumbra. Make sure to bring enough high level people, this is not an easy kill. Once dead the Ice Golem will drop six slightly dented molar from the great ice golem, enough for a whole team to get their Inferno rings from Ergo
Loot one of the Molars and head north to Ergo, hand it to him in return for your Sanguine Ring
