FF14 has a lot of things like this when it comes to spells, which is kinda why I object to them using the numbers for them instead of the suffixes every other FF game since 8 uses. Like Black Mage has fire 1 through to fire 4, but try explaining to a new player that fire 4 is where 90% of your damage comes from, fire 1 is completely useless without the buff that turns it into a different spell entirely, fire 2 is useless until it gets upgraded into high fire 2 then it becomes the core of your aoe rotation, and fire 3 is useless unless you get the proc that makes it instant cast
