Despite being one of the biggest elemental resistance inhibitors, Rune Master lacks enough to make him stand out amongst other classes. Many other magical classes outdamage him and others also give better supports than he does. I am suggesting improvements to help with his skillset to increase his clearing range, skill damage, defense ignore, and to provide more support effects.
Skills:
Rune Field: Current buffs + Party has 80% damage reduction for 1s upon casting, then switches to 20% damage reduction for the remaining duration
Unmodded Phoenix Talon:
-Heals party HP/MP instantly and gives healing buff for 5s
-3 MP per second buff removed
-Party members gain speed buff for 15s after healing
Unmodded Luna Blade now freezes enemies upon hit for 5s after burning their MP
Enchant Dash increases party elemental activation chance by 5% for 15s
[Mod] Splash Explosion Rune Protection buff applies to allies as well, and additionally removes debuffs and prevents debuffs to all members for 5s
Both Critical Swords: Affect allies
[Mod] Extreme Rune Buster ignores target's defense by 50%; skill is shortened by 50% to be faster
Extreme Rune Buster has increased vertical range and gives targets all 3 debuffs for 10s
[Mod] Phoenix Talon does not return to the caster and has greater forward range for clearing
[Mod] Rising Slash: Summon three magic rune swords in front of you
Overs Geyser inflicts burn for 5s and ignores defense by 20%
Lodestar usable in air
[Mod] Sword Fire changed to shoot three flaming slashes forward in a fan shape (usable in air)
Passives:
Thinking Outside the Box: All Damage increased based on how low target's elemental resistance is (max: 50% damage increase)
Magic Chain: Now overlaps with Oz Sorceror's Petite Angkor debuff
Mana Flow:
-New buff that increase party’s max MP by 50 upon awakening, for 30s
Magic Coating:
-New buff upon using Iron Body - caster and allies gain 10 MP per second, projectile absorption, and all speed increase for 7s
