Besides Mimic or Tiche, what are the best summons for the Fire Giant?

[Einstine]

As a Mage fully into INT?

[SHOCKNUTZ]

anything that can bait him really. best to summon on p2 of the fight though. the only time i used a spirit on him i used stormhawk. agro/tank/fast evasion, continuous ap buff to my damage.

[paladin181]

Lhutel the Headless is pretty good.

[Sabaithal]

Something very tanky. I'd imagine Ancient Dragon Knight Kristoff would be good considering his/her very high defensive and tank capability, and ranged lightning attacks.

You could also try Redmane Knight Olga, who is unchained so will attack from very long range persistently, and you would never have to worry about getting too far from them.

Tiche might not perform well due to the sheer range and area of the fire giant attacks. Her strength is primarily to evade attacks outright, which would be somewhat difficult.

[Chrono]

I had mimic/black knight tiche bait him and i hit him with scarlet rot every once in a while once he was in 2nd stage

[Sparhawk 59]

If you are going to summon anyway nothing better than another human player. Just make a thread asking for help add a password

[Twisty]

Ancestral follower is pretty good at pick damage from range.
Lhutel can close gaps and is tanky.
