Summoner getting ganged up on

[Kirika-]

Titan-egi gives you defensive buffs.
Upgrade your accessories to Agate / Mithrite crafted, until you can afford the tombstones to replace them with Ironworks accessories. With a full Ironwork gear set, you can go all the way to L60 and still be effectively geared.
Buy or make a https://na.finalfantasyxiv.com/lodes...m/be389a2ad4c/ to replace you current Grimoire.
You will then have much greater survivability.

Also, don't forget, your Arcanist job forked to Summoner and Scholar after your L30 job quest, so you also have a L55 Healer job you can use once you unlock it
The Summoner and Scholar jobs share the same player level, so even if you level only Summoner to max, the Scholar job will also be max level, you just have to do the jobs quests and gear up with Healer gears.

Lastly, the Physick spell basically becomes fairly useless for Summoner after L30+, as it's tied to the Healing attribute Mind, of which becomes a stat that isn't gear buffed for Caster jobs (INT is the Caster main stat), so it becomes so under powered post L30 on Summoner that it is a waste of mana and time to use.
Play the Summoner as a job that out DPS's the enemies to survive the battle, in that you kill them before they kill you.
If you are not out damaging the enemy, then take note of what you are casting and what skills you are using, and try those that can dish out the damage fast and consistently.
Also, choose a pet for the right situation.

• If enemy stays back or is occupied by a tank, use Ifrit
• If enemies cluster, use Garuda
• If enemies gang up on you, use Titan

Oh, one last thing, don't forget your Chocobo.... As you level it up it can become your tank, your healer, your DPS, or all three.
