Butterfly Wing

Source: npc/quests/first_class/tu_acolyte.txt

Butterfly Wing is given in the Acolyte training line with Sister Asthe.

1. Go to prt_monk 230,106 and talk to Asthe#tu.
2. Progress her training until the Heal skill checkpoint stage.
3. At the step where she sends you out to train Heal to level 3, she gives:
• Mace (getitem 1504,1)
• Butterfly Wing (getitem 602,1)
4. Use that Butterfly Wing to return quickly after training Heal, exactly as she instructs.

Key line from Asthe:
• Once you've learned Level 3 Heal, you can use a Butterfly Wing to return here.

Result:
• This is a guaranteed item handout at that specific training stage.
