Sulphur Sanctum

Information
The Sulphur Sanctum is the hub for the Weekly Bosses Chalconnis and Chalconnis EX. It is located deep underground, but marked aboveground by the presence of a beacon with an orange beam. After beating Chalconnis or Chalconnis EX once and acquiring 1 Sorcerous Sulphur, players have the option to unlock a train station in Laundry Town by using the Sorcerous Sulphur on Saulphur Gooman.

Sulphur Confessor Scorian
Sulphur Confessor Scorian greets players at the entrance to the Sulphur Sanctum and gives them key information.

Dialogue

 * Welcome traveller, to the Sulphur Sanctum, and may its blessings be upon you.
 * Here, we tend to great elemental Chalconnis, who roils deep below us. Have you ever wondered how the surrounding forests stay lush, and how the springs flow continually? It is the work of Chalconnis.
 * Yes, the sulphur can be toxic to some of the surrounding greenery, but the springs themselves carry vital minerals and nutrients to the surroundings, resulting in abundant growth. We use the ample sulphur to augment our tools and arms.
 * Our Speaker divines the needs of Chalconnis, and she produces a charm that will rouse Chalconnis from its dormancy to do battle with the brave few chosen to rouse its spirits and bolster the flow of the springs. You may participate in such a ritual.
 * Approach the Speaker once a week to claim a charm, and bring it to the Keeper to do battle. Up to three of your allies may join you for a single use of your charm. Note that it will be expended on use, and you cannot re-enter the chamber.
 * Should you prove successful, we will award you a small offering, and some sulphur that you may present to our smith for some of his wares. Should you require more charms, our Supplier may part with some if you can provide us other material need.

Sulphur Speaker Lahar
Sulphur Speaker Lahar awards 1 Sulphur Charm per week to serve as the Boss key. This resets each week at 12 PM EST on Mondays, so keep that in mind when redeeming keys!

Dialogue

 * I have coalesced a charm for you. Pray, take it and bring us prosperity. Return again in a week.

Sulphur Keeper Mafic
Sulphur Keeper Mafic allows players to use 1 Sulphur Charm or 1 Searing Sulphur Charm to enter the arena. Players must be diligent and enter the arena before it closes, or else the key will be wasted.

Dialogue

 * Bring me a Charm, and I can open the way.

Sulphur Supplier Breccia
Sulphur Supplier Breccia offers some wares related to keys and SoxBux. Players can buy new keys if they wish to challenge Chalconnis again more than once a week, or gain more information on how to defeat Chalconnis.

Dialogue

 * Mm.. yes. I have extra charms, but they'll cost you. Don't expect to profit much if you do this, but at least you'll get some sulphur.

Sulphur Smith Rhyo
Sulphur Smith Rhyo offers wares for Sorcerous Sulphur. These wares can aid you in the fight against Chalconnis itself, or be used in the world against or with other players.

Dialogue

 * I'm not much for the monastic values of these folks, but there's no denying the strength of this sulphur. Bring me some and I'll see what I can cobble together for you.

Auto Attacks
Chalconnis fires a blast of toxic fumes! - Small unavoidable damage with some knockback.

Fissures around the arena begin leaking steam... - Small white fumes spawn around the arena that proc poison if you stand on them for too long.

Prompted Attacks
Sulphur debris crumbles off of Chalconnis and rises as sprites! - Summons a set of 4 empowered Blaze sprites that both do more damage and have more health than usual Blazes. If left alive for too long, will eventually buff the boss.

Chalconnis focuses a jet at a player! - Chalconnis's most dangerous move if it's targeting you. If this move isn't targeting you, it'll do no damage. Its a constant blue beam/wave that will track a player at random. Who the beam targets does not determine who the beam damages. If Chalconnis is targeting a player with the beam, and is facing another player, the player targeted by the beam will not be dealt damage.

A shrill hiss emanates from Chalconnis as pressure builds within it.. followed by A scalding wall of vapour splits the arena! - Chalconnis sticks its out and summons a pair of steam walls that rotate around the arena. No other move can be performed by it while this move is active. The wall extends beneath the poisonous waters and has a very small chance to proc True damage worth 5 hearts, which goes through armor.

A surge of sulphur builds behind a player! followed by Chalconnis rapidly draws the sulphur forward! - Chalconnis places a burst of sulphur behind a targeted player, and after a few seconds, draws the player into the central pool. The attack itself is harmless, but the poison damage from the water is not.

The outer ring of the arena rumbles... it's about to collapse! - When Chalconnis's health is below half, it will make the arena smaller by removing the outer ring. A pool of poisonous water forms, with geysers (marked by dripstone) available for fallen players to escape with.

Strategy
The Catalytic Charm from Sulphur Smith Rhyo is useful for cleansing poison from you and from others around you. When used, it clears poison from you and others around you and grants absorption in its place. Falling into the water is also dangerous- take care to find a geyser to escape from. Additionally, if you are being targeted by Chalconnis, take extra care to not be hit by the blue beam. If it pins you, you're as good as dead. Run around the arena as close to Chalconnis as you can to force the beam to travel behind you, as it can't catch up with you (as opposed to running on the outside of the arena, by the wall).
