This page contains a beginner’s guide on Command Spells in Fate Grand Order (FGO), as well as situation where they are most favorable to use.
In Fate Grand Order (FGO), the Master (player) has access to three powerful commands to be able to increase his or her party of Servants‘ potential in combat.
One Command Spell will allow you to either fully restore the HP of one of your Servants, or charge their NP Gauge to maximum. As a trump card of sorts, you can also use three Command Spells to revive your entire party to full HP with each having maximum NP gauges after the party has been wiped out. Note that the starting characters will remain as before. This all-out Command Spell will allow you to deal extremely high damage on enemies to reverse the tide of battle.
Despite this, it is important to know that Command Spells regenerate at a rate of 1 per day. You will not be able to have more than 3 of them at a time, so it is important to choose carefully when you will use up all of them at a time. One good situation to use them is during Special Events where you need to defeat powerful bosses that have massive amounts of HP.
Should the entire party be defeated without access to three Command Spells, you will be able to spend 1 Saint Quartz to revive them instead.
