TL;DR — Zalcano is a skilling boss in Prifddinas: you never swing a weapon. Mine tephra → smith it → imbue it → throw it to break her armour → then mine the boss. Damage scales with your Mining/Smithing/Runecraft, not combat. ~220K per kill average, up to ~2.3M/hr in efficient groups, with the crystal tool seed and the Smolcano pet as chase drops. Ideal for skillers and anyone tired of prayer flicking.

39/8,000 (~1/205)
Requirements
- Song of the Elves completed (Zalcano lives under Prifddinas).
- 70 Mining + 70 Smithing to get into Prifddinas at all; higher = more damage. Runecraft also boosts your tephra damage.
- Bring your best pickaxe, sturdy armour (she chips you with rocks), food, and stamina/energy potions.
How the fight works
1 · Mine tephra
Mine glowing rock formations around the room for
tephra.
2 · Smith it
Refine tephra at the furnace into refined tephra.
3 · Imbue it
Charge it at the altar →
imbued tephra — your "ammo". Damage scales with (Smithing + Runecraft).
4 · Throw & mine
Throw imbued tephra to break Zalcano's stone armour, then
attack her with your pickaxe while she's down. Stand on the
blue demonic symbols for +50% damage. Repeat until dead.
Staying alive
- Falling rocks — shadows appear on your tile a moment before impact. Step off.
- Glowing red rocks — she powers up certain formations; mining those hurts you. Switch spots.
- Golem — she spawns one that walks to the altar; players body-block/kill it with tephra or it heals her.
Loot is contribution-based: your share of damage (both tephra and pickaxe) decides your drop rolls. Leeching in a mass = tiny loot. Throw your tephra.

- Stand on blue symbols whenever you throw — +50% damage is massive over a trip.
- Bank the crystal shards — they're the fuel for crystal tools/armour from our Gauntlet guide.
