Barding Difficulty

Barding Difficulty is the hidden per-creature value that gates every check by the four bardic skills — Provocation, Discordance, Peacemaking, and the bard masteries layered on top. Every monster carries a single internal barding rating: the Bard's combined Musicianship + bard-skill + instrument bonus is rolled against twice that rating to determine success. Like Taming Difficulty, it is the single most important number a Bard needs to know about any new target — it dictates which creatures are bardable on the current build, where the next training plateau sits, and which two creatures can safely be Provoked against each other.

The Crystal Ball of Knowledge — purchased from Bard NPCs — reads any creature's Barding Difficulty when targeted; the ball reports both the value and whether the player's current skill level is sufficient. Veterans memorise the canonical ladder for their training tier and reach for the ball only when checking an unfamiliar mob.

The success formula

The check used by all three bard skills follows the same shape:

EffectiveSkill = (Musicianship + BardingSkill + InstrumentBonus) / 2
Success if EffectiveSkill ≥ random(0, BardingDifficulty * 2)

In practice, the margin to 100% chance is roughly 20 effective points above the difficulty — a Bard at 120 Music + 120 Provocation has Effective Skill 120 against a target whose Barding Difficulty is 100.0 or below, scaling down toward roughly 50% chance when Effective Skill equals the Difficulty.

For Provocation specifically, the formula does not average the two targets — it uses the harder of the two Barding Difficulty values. Provoking a Cu Sidhe onto a Yamandon checks against the Yamandon's number, not the Cu's. This is why veteran Bards memorise the difficulty of their stronger mob and ignore the weaker one when planning a fight.

Provocation, Discordance, and Peacemaking — same check, different effects

All three roll against the same Barding Difficulty value. A creature that is 95.0 difficulty for Provocation is also 95.0 difficulty for Discord and Peace — the rating is per-creature, not per-skill.

The difficulty ladder

These are the canonical reference points for a Bard's training and end-game targets:

Animals and low-tier (training cap)

Mid-tier (the post-65 plateau)

Advanced (the canonical 100–120 range)

The post-115 tier is the canonical "Bard at the cap" range — even a fully-scrolled 120 Music + 120 bardic target needs the maximum +20% slayer instrument bonus (matching) to reliably succeed against a Balron or Yamandon. Without a matching slayer, those creatures sit at chance < 50% even at 120/120.

Instrument bonus

The bardic instrument carried in the Bard's pack contributes directly to the Effective Skill term in the formula:

A Bard wielding a non-matching slayer instrument has their Effective Skill reduced by 20% — at training plateaus this shifts the gain check back into the productive zone, accelerating skill gain even though the success rate drops. The classic example is using a Repond Slayer (orcs/ogres/trolls) against a Giant Beetle (which is not Repond). The 20% effective penalty pushes the gain check back into the sweet spot.

Range

Every bardic ability has an 8-tile base range that grows by 1 tile per 15 skill points above 0. At 120 Provocation the working range is 16 tiles — wider than the screen by a comfortable margin. The Bard must remain within range to maintain the song; stepping outside, breaking line of sight for more than ~10 seconds, or dying all end the effect.

Bard masteries — the +20 effective layer

The Skill Masteries revamp added bard-specific masteries that further modify the check:

• Provocation Mastery (Resilience) — reduces incoming damage to the Bard during Provocation attempts
• Discordance Mastery (Tribulation) — applies a damage-amplifying debuff to Discord targets
• Peacemaking Mastery (Despair) — area peacemaking with stronger duration
• Inspire — party-wide damage and DCI buff
• Invigorate — party-wide healing buff
• Perseverance — party-wide HPR/Stam regen buff

The masteries add new effect layers but do not change the base Barding Difficulty value or the underlying success formula. They are layered on top after the success roll lands.

Why difficulty is fractional skill (not a percentage)

The reason Barding Difficulty is quoted in fractional skill points (89.0, 107.0, 117.0) — and not as a percentage — is that the success formula consumes the value directly. The check is Effective Skill ≥ random(0, Difficulty × 2), so the Difficulty is acting as the upper bound of a uniform-roll term. This is deliberate parallel to Taming Difficulty, which uses the same fractional-skill threshold notation for its own (Taming + Lore) check.

Some references list the "minimum skill" (the floor at which chance is non-zero) and others list the "100% chance skill" (the ceiling above which chance is capped at 1.0). Both refer to the same Barding Difficulty number; the difference is roughly +20 effective points between the floor and the ceiling.
