Tank Mitigation vs Tank DPS.

[RareItems]

Don't raid but i do a lot of leveling dungeons. Skillspeed and Tenacity materia are great and cheap. It might still be Tenacity + Determination for PLD since PLD has magic attacks and heals. Crit is always a good 3rd materia option for all of them. But definitely Tenacity first lol. I've seen so many tanks dying to simple tankbusters because they loaded their gear with Direct Hit and Crit materia or taking so much damage on large pulls.

Tenacity reduces incoming damage by 1% for every 100 Tenacity and also increases your damage by 1% for every 100 Tenacity if your a Tank.
