→
Magic
Up to 10. Protect from Magic before opening the gate: she attacks on sight.
→
Crush
Up to 16, only if you are in reach. She does not approach: fight from range.
⚠→🚫
Growthlings
1/5 chance to summon 3; she is immune while they live. Kill them ONLY with an axe or Magic secateurs; a Bronze axe is on the log pile.
⚠→🚫
Poison
On members worlds she poisons (8). Bring antipoison even while praying.

Step by step

  1. Mossy key from Moss giants. Entrance east of them in the sewer (cut the web) or the 51 Agility shortcut from Edgeville Dungeon.
  2. Protect from Magic and open the gate.
  3. 50% weak to fire: Fire Blast with a Staff of fire is strongest at low level. Or ranged in d'hide from a distance.
  4. If growthlings appear, wield the axe and one-shot them. Back to her.
  5. Once dead, open the chest with the Mossy key: the only source of Bryophyta's essence.

Ironman tips

  • 💡 She drops Mossy keys at 1/16 (1/8 on a moss giant task). Kill her without a key to stack them and open the chest later.
  • 💡 The staff stores nature runes and sometimes does not consume them: big alching savings. With Dragon claws or Voidwaker she dies in seconds.
