Topaz or Ifrit-Egi, which is useful in dungeon areas?

[Ecks007]

Yes, they generate enmity. But enmity is only stolen if there isn't sufficient aggro on the mob in the first place.

It becomes a constant battle because, yes a tank can generate enmity enough to hold the monsters, but all of Titan-Egi's attacks generate emnity as if he was trying to tank. Tanks then have to put even more effort into making sure their enmity is the highest because they have a Summoner's pet constantly trying to battle it away from them as that is Titan-Egi/Topaz Carbuncle's job.

And as others have said already. It's quite easy to keep Ifrit-Egi alive. Use Sustain relatively frequently when you see it taking damage. Or do yourself a favor and level up Thaumaturge/Black Mage for Swift Cast so that if you aren't going to keep Ifrit alive with Sustain you can at least instantly re-summon him when he dies.

It makes no sense for a summoner to use their tanking pet unless it's some kind of already agreed upon strategy in party of abnormal make-up. (ie. no tank class/job)

Is there a sustain option for Ifrit? Can't remember, but I only have it for the Topaz.

Sustain is a lvl 18 Arcanist skill. It is used with all pets to give them a heal over time. When you get Rouse at lvl 42 it can be used before Sustain to boost Sustain's healing effectiveness (as well as Physick/Cure heals on your pet).
