Pflug is a Rune Fencer ability in Final Fantasy XI at level 40. It can be recast every 3 minutes and lasts for 2 minutes. It greatly increases resistance to status ailments that correspond with the runes currently active. The effect is further enhanced by more runes of the same type being active. For example, Flabra runes being active will make the player incredibly resistant to Petrification. Likewise, Tellus grants strong resistance to Stun.
