This Seeking Tech guide will show you how to beat the last boss in Final Fantasy V Pixel Remaster.
The difficulty of these fights will depend on the abilities you have equipped. You should use Dualcast since it will allow you to use magic twice, which is extremely helpful for both healing and attacking. It is also a good idea to have at least one white magic user.
When it comes to hurting Exdeath, you can dual cast the Flare and Holy spells.
While these Flare and Holy are also helpful against Neo Exdeath, summoning Bahamut is more effective since he can hit multiple targets at once. If you don’t have Bahamut, then you can use the Zeninage ability to attack all parts of the second form.
