RPG Insanity

The best equipment, in terms of attack and defense, can be found in chests in the 2 post normal end dungeons.

The best weapons are found in the abyssal caves

Salvator weapon and armor arguably better than non IAP gacha equipment.
Equipment slots amount is more valuable. With 4 slots weapon you can put Phys/Mag dmg up + Str/Int + Spd + Critical.

And the armor comes with most broken option. Lethal damage prevention from this armor doesnt have use limit unlike other source. With hp recovery and enough speed you wont die. Since the armor have 4 slot you can put HP up, HP recovery, Phys dmg reduce, Mag dmg and get tankier than higher def armor. I give the armor to Beruna.

 

Beating all arena medium unlock Augment Charm in arena shop. This accessory increase dropped weapon and armor upgrade by 5 and wearing multiple stacks. With 5 equipped your gear drop become +25-30.
