Please consider the following changes to remove hotbar bloat from Black Mage in Expansion 3 (5.0):

== Freeze
Potentially remove, it's one of the least used spells.

== Blizzard II
Increase its damage after removing Freeze, IE: via a trait through the quest that normally awards Freeze.

== Fire
Make a trait given at level 60 that upgrades Fire to Fire IV, meaning Firestarter will affect/effect Fire IV as well and award free Fire III casts from Fire IV. (After doing this, you will have to re-nerf Fire IV's damage potency for balance from Patch 4.2's Black Mage changes.)

== Blizzard
Make a trait given at level 58 that upgrades Blizzard to Blizzard IV. Also award Umbral hearts (one at a time) to Blizzard for continuity.

== Drain
An alternative award for the quest that gives Freeze if it's removed, is an increase in Drain Potency / Reduction in Convert's cost, as Black Mage has no way to sustain itself besides Drain / Chocobos.

== Ley Lines
Remove this and "Between the Lines," instead giving a cast time reduction upgrade at level 52.

== Between the Lines
The quest that awards this will instead give an upgrade to "Aetherial Manipulation," which allows it to be ground targeted if no player character or party member is currently targeted.
