Petrified Lichen Guard

The Petrified Lichen Guard is purchasable from the Sporeggar Quartermaster Mycah once you are with the Sporeggar faction. It also costs 15 Glowcaps.

The effect "Afflicts your attacker with deadly poison spores each time you block." causes a stacking debuff to anything whose attack the player blocks. This debuff stacks to 5, starting at 12 nature damage every 3 seconds and stacking to 60 nature damage every 3 seconds. Does not appear to be affected by +Spell Damage effects. This is an excellent shield for a Protection Pally to AoE grind with.
