Zalcano

Strategy

An overview of Zalcano's prison. To the west, the blue altar. To the east, the red furnace. In the corners, the four rock formations.

Helpful info

• To know the minimum amount of tephra each player on your team will need to mine, divide 30 by the number of players in the room, rounding up, as each imbued tephra deals ~10 damage (~15 when standing on a blue symbol), and her armour has 300 hitpoints.
• The optimal team size to maximise loot whilst still killing Zalcano consistently in three phases is 4.
• There are several clan chats available to find worlds with optimum group sizes.
• Big rocks will fall from the ceiling quite often, dealing ~40 damage, if not dodged by walking to a different tile. They are telegraphed by debris falling down, indicating where it'll fall. Watch out for these when you're standing still, or running to a place where other players are standing still.
• Zalcano will spawn orange/blue demonic symbols occasionally. Running over an orange symbol deals more damage the longer it has been active, whilst also lowering your run energy. Orange symbols hit up to 26 damage and should be avoided when running around the room. The blue symbols boost damage and accuracy when throwing imbued tephra.
• Players can expect to get roughly 13,500 Mining, 3,000 Smithing and 1,500 Runecraft experience per hour when killing Zalcano efficiently.

Inventory

• 1-3 stamina potions.
• An eternal teleport crystal or a regular teleport crystal to teleport back to Prifddinas should you die. You can also speak to Crefydd, who can be found in the centre of Prifddinas, and set your respawn point to Prifddinas for free.
• Some empty slots for tephra/loot.
• The remaining slots should be Saradomin brews, summer pies or the food of your choosing. If you pay enough attention, you shouldn't need too much food.
• Some players opt to carry a rune pouch to store the rune drops, saving inventory space for additional tephra.

Making imbued tephra

A player mining a glowing rock formation. The falling debris above the player indicates that a boulder is about to fall on top them.

In order to remove Zalcano's armour, and mine her when it's removed, players must make imbued tephra and throw this at her.

• First, mine the glowing rock formation in one of the four corners of the prison, this will provide you with tephra. The non-glowing rock formations give tephra at a vastly reduced rate, so always mine from the glowing ones.
  • When Zalcano first spawns, the rock formation in the north-east corner has the highest chance of glowing. If not north-east, it can spawn in any of the other corners. Previously, it could not spawn in the south-west at the beginning of the fight.
  • Watch out for Zalcano targeting the glowing rock with a magic attack, as this will make the rock explode, dealing ~30 damage to anyone still standing next to it. Another rock will start glowing instantly. Relocate to this one if you haven't acquired enough tephra yet.
• Secondly, at the furnace on the eastern side of the prison, refine your tephra into refined tephra.
• Thirdly, at the altar on the western side of the prison, imbue your refined tephra into imbued tephra.
• Finally, attack Zalcano.

Attacking Zalcano

Throwing imbued tephra while standing under a blue demonic symbol will increase the player's accuracy and damage.

• Imbued tephra do not need to be equipped in order to be used.
• When Zalcano spawns orange/blue demonic symbols, standing in the blue ones will greatly boost damage and accuracy when throwing the tephra.
• Saving tephra until Zalcano spawns the blue symbols will allow them to be used more effectively, eliminating the time-consuming process of creating more.

When determing whether to throw remaining tephra or save them, multiply the number of remaining tephra by 15 and number of players in battle. If this number is close to Zalcano's remaining armour hitpoints, it may be worthwhile to save the tephra.

• When Zalcano fires her magic attack at a wall instead of a glowing rock formation, a golem possessing 14 hitpoints spawns, healing Zalcano for 50 armour (or a percentage thereof if it has been damaged).
  • In larger teams (8+ players), the golem can be safely ignored.
  • In smaller teams, the golem can be killed by throwing imbued tephra at it. When killed, it drops a stack of 16-24 imbued tephra to the player who dealt the most damage to it. If a player picks these up, any remaining tephra can be thrown at Zalcano as these additional tephra will result in that player destroying her armour eventually.
• When her armour is depleted, Zalcano drops to the floor and becomes vulnerable.

Mining Zalcano

A player mines Zalcano after breaking her stone armour.

• Stand near to Zalcano when her armour's hitpoints are approaching zero, as this will let you start mining her faster.
• Do not walk under her, as this will result in receiving approximately 7 damage per tick.
• After enough time has passed (a random number between 12-16 seconds), or when the players have dealt 380 damage, she'll get up, ready to fight.
  • Her armour resets to 300 hitpoints.
  • A shock wave destroys all remaining tephra. Don't start mining before this happens, or your freshly mined tephra will also get destroyed.
  • Anyone standing next to her will be tossed a few tiles away, and be stunned for 1-2 ticks, receiving approximately 10 damage.
• Go back to the first part and do it all over, until her hitpoints reach zero!

List of Zalcano's attacks

Zalcano has six different attacks that the player must watch out for as they attempt to take on the stone demon. Each of the attacks are performed at random intervals throughout the fight.

• Zalcano stomps the ground, causing boulders to fall from the ceiling. These can be avoided by moving at least one tile. Boulders are easily spotted by checking for falling debris/shadows on the floor, which will be followed by the falling boulder. Players who are hit by these can take 40+ damage.
• Zalcano summons blue and orange demonic symbols spread around the room.
  • Touching the blue demonic symbols has no negative effect, rather, when attacking Zalcano with imbued tephra, it will greatly increase the player's accuracy and damage.
  • Touching the orange symbols will deal more damage the longer they've been active, up to 26, whilst also lowering your run energy.
    • There are several patterns in which symbols will appear, chosen at random. 2-4 of the symbols that appear will be blue, and the rest will be orange. It is random which symbols will be blue.
• Zalcano fires a red ball of energy towards a wall in the prison. This summons a golem that will, if it reaches her, restore her armour's health based on the health of the golem.
  • If the golem is at full health, it will restore 50 hitpoints towards her armour.
  • It is possible for a player to damage the golem by throwing imbued tephra at it. The golem drops 16-24 imbued tephra when killed.
• Zalcano will fire a red ball of energy at the current glowing red rock formation to deactivate it. If a player is standing near the rock formation when this happens, they will take up to 28 damage. These can be avoided by walking away from the rock. A different rock will start glowing immediately.
• After Zalcano has fallen and enough time has passed, or players have caused enough damage, she will rise again. If any players are standing next to her when this occurs, she creates a shock wave that pushes them away, dealing ~10 damage to them. All tephra are destroyed as well.
• Zalcano targets all players within the prison with a barrage of small pebbles. These are unavoidable, but players will only take ~5 damage.
