Class Changes

Last updated: October 6, 2026

uaRO uses the pre-renewal class system, with selected adjustments to skills and mechanics for balance and smoother gameplay. These changes preserve the classic feel while improving the overall experience.

In the tables below, Original is the official pre-renewal behavior and uaRO Changes is how uaRO differs from it.

For full reference on unmodified pre-renewal skills, you can visit the external classic wiki.

General / Shared

Skill	Original	uaRO Changes
Party Buff Animations	Buffs from party members play their full animation delay on every recipient.	Delay removed for party members, so the buff lands instantly with the effect and a floating skill name. The caster still sees the full animation. Covers Angelus, Magnificat, Gloria, Wind Walk, Adrenaline Rush, Full Adrenaline Rush, Weapon Perfection, Over Thrust, Help Angel, and the Blessing, Increase AGI and Assumptio scrolls.
Reflected Damage (skills and equipment effects)	Reflects the listed percentage of damage taken, with no limit.	Reflected damage cannot exceed the max HP of the skill's user. For example, with 5,000 max HP, an attack for 10,000 reflects at most 5,000.
Safety Wall	Players inside can reflect damage with reflect skills.	Players inside cannot reflect damage with reflect skills.
Fury / Critical Explosion	Natural SP recovery is disabled while in Fury.	Natural HP and SP recovery work while in Fury. Does not apply to Monk or Champion. Other characters, such as those who get Fury from an item, benefit from the change.
Teleport	Teleports to a random spot on the same map.	Cannot land on a map portal.
Warp Portal	Can be used on MVP maps.	Cannot be used on MVP maps.

Status Effects

Status effects that behave differently from the official game.

Skill	Original	uaRO Changes

Please Don't Forget Me	Not removed on death.	Removed on death.

Swordsman

Knight / Lord Knight

Skill	Original	uaRO Changes
Berserk	No items can be used while Berserked. Chat is blocked while Berserked. Red body tint while active.	Fly Wing, Novice Fly Wing, and Infinite Fly Wing can be used while Berserked (all other items remain blocked). You can chat while Berserked. The red body tint is replaced with an aura effect and a cast sound (the aura can be hidden via the Status Color Effect setting).
Concentration	Runs for its normal duration, unaffected by Berserk.	If active when you cast Berserk, it is refreshed and extended to 2.6x its normal duration (Level 5: 45 seconds to 117 seconds), and it ends when Berserk ends.
Bowling Bash	Knockback distance of 1 cell. Skill range of 1 cell.	Knockback distance of 2 cells. Skill range increased to 2 cells.

Crusader / Paladin

Skill	Original	uaRO Changes
Shield Swapping	Swapping a shield while a skill is active cancels the skill.	Swapping shields no longer interrupts the skill. Removing the shield still cancels the skill.
Devotion	Usable on party members, including non-guild members. The status icon shows on the devoted player only. No "+" marker in the party list.	Cannot be placed on non-guild members outside of Battlegrounds. The status icon shows on both the caster and the devoted player. A "+" shows next to devoted players in the party menu.
Grand Cross	Hits 1-5 times, depending on the position and movement of the enemy. Each monster on a single cell reduces the number of hits by 1 (to a minimum of one hit to one monster). Does not trigger HP leech effects.	Mobs on the same cell take 100% of the damage from every hit. All 3 waves connect with any target in range. Triggers HP leech effects, such as Hunter Fly cards.
Holy Cross	No bonus damage with a two-handed spear.	Deals 2x damage with a two-handed spear.
Shield Reflect	Returns a percentage of the damage dealt to you back to the enemy, including Boss-type monsters (MVPs).	Reflect damage no longer affects Boss-type monsters (MVPs).

Offers Earth Spike instead of Frost Diver: Level 1 from Auto Spell Level 2, Level 2 at Level 3, and Level 5 from Level 4 onward (always Level 5 under Sage Spirit). Frost Diver is removed from the list.
