What runes are for

Aim: To acquire the Scaven shield SxD8.

Equipment: Orbiter, Anomaly detector, Security Countermand, Scaven mercenaries, ability to defeat Matriarchs.

Method: First 4 steps may be taken in any order you wish.

1-Fiery/Fire rune: May be found in Magma labs when opened with a Security Countermand, as well as at the bottom of firewells.

2-Solar/Sun rune: Found after defeating the Sun Ritual on the Vulcore Plains. Must have Scaven mercenaries with you; when a warrior tells you there is a ritual going on check it out and fight your way to the Matriarch(s) to win the Solar rune and 4 Crowns. Best done at a low bm to ensure you only have 1 Matriarch as an adversary.

3-Icy/Ice rune: Found in Scaven Settlements after defeating the Ice Queen. Anomaly Detector is needed to show you which Settlement is ruled by an Ice Queen (shows up as blue writing), and once you defeat it you win the Icy rune and 1 Crown. The Ice Queen will have 200 armour, and you can only fight it once.

4-Lunar/Moon Rune: May be found in Sink Holes on the Vulcore Plateau. An Orbiter and an Anomaly Detector is needed for this step. The Lunar rune only appears in Sink Holes that have been discovered by an Anomaly Detector, and that has been booby-trapped to be defused by an Orbiter.

5-Equip at least 1 of each rune onto 1 or more of your squad bots, and go to Scaven Territory. When you arrive at a Scaven Ziggurat, open it to acquire the shield SxD8. It will arrive in your inventory.

Conclusion: Wow so THAT's what a Fiery rune is for............
