Mission 6 - The Antidote II | Gems - First pass Castlevania: LoS 2 Guide

#9 Void Gem

A hole leading to the Void Gem.

You will find another Void Gem at the beginning of the mission. Use your newly acquired skill to pass through metal bars, and stand above the airflow and use the Mist power again - it will allow you to get to the upper level. Replenish you Magic by the Magic Font, climb up the scaffolding, and then, hanging in the airflow, use Mist yet again, to get to the other side. You will land on a Shadow Portal - use it, to get into your rat form and get inside the nearby grid. Go through the tunnel, until you reach a place where you can jump down through a hole in the ground - the hole will lead you to a roof with a Pain Box containing a Void Gem.

#12 Life Gem

A collectible you left behind a few missions back - to the right there's a passage leading to it.

Jump down the roof and get all the way back to the room in which you restored power with Zobek's Lieutenant (where you had to tear the cables apart) - to get there, climb up the scaffolding (to the opposite of the place from which you collected a Void Gem a second ago), and in the next room, where you had to climb a lot, jump down and go straight ahead. Pass through the bars by using your Mist power and climb up the ladder (remember about the keyhole for a Dungeon Key, which is located near the ladder), until you reach the room in which you fought Satan's Soldier. Deal with all the enemies chasing you and climb up the scaffolding. Use your Mist power to pass through the bars in front of you, which will allow you to get to a Pain Box with a Life Gem inside.

#9 Chaos Gem

After the fight with the Riot Police (after they used proximity mines for the first time), head towards the marker on the map and climb up the wall of a building with a Windrunner signboard on it (to the left of your actual position, there's a truck, behind which you will find a Pain Box - you can't reach it just yet) to get to the other side. Jump into the hole on the right side of the street (to the opposite direction to the marker on the map) - you will find a Pain Box (with a Chaos Gem inside) there.

#10 Chaos Gem and #10 Void Gem

Notice a Pain Box in the distance.

You will enter a building consisting of several floors. Don't run up the stairs - instead, mist through the bars on your right, where you will find a Pain Box with a Chaos Gem inside. Collect it, go back to the stairs, get rid of the nearby enemies and collect a Void Gem from the mentioned Pain Box.

#13 Life Gem

A Pain Box located on the right side.

Another gem is located on the top floor of the same building. Leave the elevator and go to the right, but don't go into the corridor marked by the waypoint - instead, go straight ahead. Jump over a series of gaps, to get to a Pain Box with a Life Gem inside.
