Mechanics: what hits you and what to pray
Skilling boss under Prifddinas: mine tephra from the glowing rock, refine it at the furnace, imbue it at the altar and throw it to break her armour (300 HP). When she falls, mine her.
Left icon: what hits you. Right icon: what to pray.
Falling boulders
She stomps and rocks fall (40+), telegraphed by debris on the tile: move 1 tile.
Symbols
Orange: up to 26 and drains run energy, avoid. Blue: throw tephra from there for far more damage and accuracy.
Rock explodes
Orange ball at the glowing rock: move away or take 28. Another rock glows instantly.
Golem
Red ball at a wall: a golem heals 50 armour if it reaches her. Kill it with imbued tephra: it drops 16-24 more.
She rises
After 12-16 s of mining she gets up: destroys all tephra, pushes you and hits ~10. Never walk under her (7 per tick).
Step by step
- Teleport crystal to Prifddinas and the teleport platform to her prison.
- Mine the glowing rock (usually starts north-east); dim ones give almost nothing.
- Furnace east (refined), altar west (imbued).
- Throw it from a blue symbol; the team needs ~30 tephra per armour break.
- When she falls mine her up close and back off before she rises. Repeat.

Ironman tips
- 💡 Rhiannon swaps resources for more xp (~50k extra Mining/h); uniques still roll. Crefydd sets your respawn in Prifddinas for free.
- 💡 3-man teams give the best Crystal tool seed rate (~1/615). A crystal pickaxe adds +2 damage.
