This rune is a relic of the Legacy Chain. When an unsuspecting villain crosses one, it summons an Animated Stone, two or three Fire Imps, and a Phantasm (called "Champion of Light"). Defeating these summoned mobs won't net you any Infamy or Experience at all. The rune is also targetable and has the same Hit Points as a Minion of the same level. Apparently, if the rune is attacked and its life bar drops to 50% the pets are summoned and aggro on the attacker as well.
The Eihwaz Runes are found:
- In the the Take Down Sea Witch mission from Lorenz Ansaldo, which awards the Seaweed Badge.
- In the the Find info on coral key mission from Operative Renault, on the Operative Renault Strike Force.
These strange runes glow ominously with unstable mystic energy.
