Help please a summoner worried

[Pepsi_Plunge]

Could you list the gear you have? We can check how suitable it might be and suggestions for upgrades.

You can check the gear on the lodestone. That being said:

Shimm, you are still running around with some under level 50 gear. Your weapon is only level 45 so far. While you can and should do your summoner job-quest level 50 which grants you the basic level 50 job gear, you can (and should) also try to buy the ilevel 120 level 50 gear with poetic stones at Mor Dhona (even upgradeable to ilevel 130)

But even with the best gear available, the crystal tower has a few instant death and heavy dmg mechanics. Like in the fight against Behemoth where you will die to the meteor if you didn't hide behind a rock, or in the final fight in the Labyrinth of the Ancients against Phlegethon where Ancient Flare will kill anyone not behind the shield, activated by standing on the plattform.
