Iban blast is powerful a magic attack spell that becomes available at level 50 after completion of the Underground Pass quest. Iban blast can only be cast with an Iban staff equipped and the staff must be recharged at Flames of zamorak in the Underground Pass after only 25 casts. Iban blast costs 5 Fire-Runes and 1 Death-Rune for each cast. Before the spell can be used, the player must pay the Dark Mage in West Ardougne a large sum of 200,000 coins to repair the staff.
Despite being a "strength 25" spell, its maximum possible hit was 15 from at least 2004 onwards.
Attempting to cast the spell not having finished the quest or without the staff equipped will produce the message:
- you need the staff of iban to cast this spell
When staff is out of charges:
- you need to recharge the staff of iban
- at iban's temple
- Iban blast is unique, in that its orb is a skull.
- Due to the extremely low number of casts possible before a recharge is necessary, Iban blast was fairly ineffective for actual combat from its initial release day.
