A group skilling boss in her prison. Make imbued tephra to break her armour, then mine her. Loot scales with your contribution, and deaths are safe.
Zalcano is a group skilling boss. You break her stone armour with imbued tephra you make yourself, then mine her with a pickaxe. Mining, Smithing and Runecraft levels all make you stronger here.
| Detail | Value |
|---|---|
| Teleport | Teleport menu > Bosses > Zalcano (15,000 coins), to the prison's entry room |
| Requirements | A pickaxe. No quest (Prifddinas does not exist on Ashmarch) |
| Leaving | Pass the barrier north of the prison, then use the Teleport Platform (Channel) |
| Dying | Safe: you keep your items |
| Detail | Value |
|---|---|
| Armour | 300, reset every time she gets up |
| Hitpoints | 1,000 |
| Fights | One at a time; everyone on the prison floor takes part. She returns about 22 seconds after dying |
| Prayers | Every attack is typeless, so prayers don't help |
1. Mine tephra from the glowing rock formation (35.2 Mining XP each). Only one of the four rocks glows at a time, and it moves when Zalcano blasts it.
2. Refine it at the furnace (10 Smithing XP) and 3. imbue it at the altar (5 Runecraft XP). Imbued tephra stacks.
4. Throw it at Zalcano. Each throw hits up to 5 + (Smithing + Runecraft) / 14, and 50% more from a blue demonic symbol. Spells and weapons do nothing.
5. Mine her. When her armour breaks she collapses for 12 to 16 seconds. Mine her for up to 30 to 33 damage a swing and 35.2 Mining XP per swing. When she rises, the shockwave destroys all imbued tephra and knocks back anyone next to her for about 10, so throw everything first and step away.
| Attack | What to do |
|---|---|
| Falling rocks (40+) | Debris marks the tile: step off it |
| Energy ball at the glowing rock (21 to 30) | Don't stand next to the glowing rock when she casts |
| Demonic symbols | Blue boosts your throws. Orange ones turn harmful after a few seconds (up to 26) and drain run energy: move off |
| Pebble barrage (1 to 5) | Hits everyone; unavoidable |
| Golem | Rises when her ball misses and walks to her; if it reaches her it restores up to 50 armour. It has 14 hitpoints and drops 16 to 24 imbued tephra |
| Standing under her | 3 to 10 damage a tick |
You need 5 damage to her armour for a reward, and 31 damage in total to roll the uniques and pet. Loot scales with H + 2 x S (H = hitpoints damage, S = armour damage). The MVP gets 10% more loot, 3 crystal shards and infernal ashes. Everyone eligible gets crystal shards and one roll of runes, essence, ores, bars, gems or onyx bolt tips. Talk to Rhiannon to take Mining XP instead of resources.
| Unique | Chance |
|---|---|
| Crystal tool seed | about 1/205 at full contribution |
| Uncut onyx | 1/8,000 at full contribution |
| Zalcano shard | 1/750 to 1/1,500 (by contribution) |
| Smolcano (pet) | 1/2,250 |
Tephra stays in the prison: it is removed when you leave or log out.
