Heavy Flame Legion Armor - Best Rune to Use?
I use ruby orbs on my full zerker warrior that I use specifically on dungeon runs only. If my warrior is my main, i would then use soldier with melandru runes.
Ruby orbs are your best option. If you find a group that you run with on a regular basis that you trust (and also don’t drop below 90% health during boss fights) you can swap to Runes of the Scholar for more damage, but if you do stay lower than 90% health for at least half of the fight, just run with Ruby.
