Hello. Trade windows full of caster weapons often raise the same questions: “If the skills on this Crystal Sword are good, is that enough?” and “How is a Flail different from a scepter?” Today that split is laid out from the game source data.

Short version: for caster use, Crystal Sword and Flail are about skills (or runeword sockets). Melee-grade mods are almost worthless. Class weapons — scepters, wands, orbs, staves — are a different item.

1. [Data] Cast speed does not use weapon base speed

The speed column in weapons.txt is only for the auto-attack motion (WSM). Spell frames use each class’s Faster Cast Rate breakpoints. Whether the weapon in hand is “fast” or “slow” is not in that math.

A Flail looks faster than a Crystal Sword at speed -10, but Blessed Hammer or Blizzard does not care. The damage range (1-24 vs 5-15) also does nothing while you are casting.

The speed a caster feels is whether Faster Cast Rate actually rolled, and whether that FCR crossed a class breakpoint.

2. Why Crystal Sword and Flail never roll FCR or mana

The cast-speed suffixes in magicsuffix.txt have a very narrow item-type gate.

• of the Apprentice (+10 FCR): rod (scepter / wand / staff), ring, amulet, orb, circlet
• of the Magus (+20 FCR): rod, orb, circlet (the expansion row excludes scepters via etype)

Swords (swor) and maces (mace) are not on that list. Mana and energy suffixes are also tied to rod / orb / scepter, so Crystal Sword and Flail cannot roll FCR or mana as a suffix.

So the “good mods” on a magic/rare Crystal Sword or Flail are usually one of these:

1. Enhanced Damage, Increased Attack Speed, Attack Rating — auto-attack
2. Life, resists — a nice bonus if present
3. Paladin skill prefixes — this is what casters actually buy

(1) barely adds damage while you cast. A sword with high Enhanced Damage and no skills is often worse for a caster than a white base.

3. The real class-weapon gap: StaffMods

The StaffMods column in itemtypes.txt decides whether white / magic / rare items can roll a class skill (+1–3).

A scepter can roll Blessed Hammer +3 from white, then stack Paladin skills +2 as a magic prefix and FCR / mana as a suffix. Crystal Sword and Flail do not have that individual-skill layer at all.

Orbs also get auto prefix 303 (life/mana auto affix), so class weapons are the “several layers of mods” side.

4. Then where do Crystal Sword and Flail skills come from?

Normal swords and maces still roll Paladin skill prefixes. From magicprefix.txt:

1. Combat Skills +1–3 (Lion/Hawk/Rose Branded, skilltab 9): scepter, sword, mace, shield, Paladin shield, amulet, circlet
2. Offensive Auras +1–3 (Captain's/Commander's/Marshal's, skilltab 10): same types
3. Paladin Skills +1–2 (Monk's/Priest's): sword, mace, hammer, shield (level 27 / 58)

The Defensive Auras tab is shield / amulet / circlet only. It does not roll on weapons.

One more limit: Combat Skills +3 and Offensive Auras +3 are magic-only (rare column empty). On a rare Crystal Sword, tab +2 is the cap.

Warlock-only, swords can roll a few extra skill-tab prefixes (swor gate). Flail (mace) does not have those rows.

So casters pick these two bases not for “mod width,” but because Paladin tab skills open on swords and maces, and because they are cheap runeword bases.

5. As a runeword, look at sockets and requirements only

Runewords go into white / gray socketed items, not magic/rare. Enhanced Damage or Superior on the base does not add to a caster runeword.

runes.txt splits the roles like this.

1. Spirit — types swor, shld only. Cannot be made in a Flail. That is why Crystal Sword is the starter pick (Strength 43, Dexterity 0, Larzuk 4 sockets). Variable rolls are FCR 25-35, Mana 89-112, Magic Absorb 3-8. +2 All Skills is fixed.
2. Heart of the Oak — types staf, mace. Flail is the lowest-requirement mace (Strength 41, Dexterity 35). Cannot be made in a Crystal Sword. +3 All Skills and FCR 40 are fixed. Variable is All Resistances 30-40.
3. Call to Arms — type weap, 5 sockets. Crystal Sword (max 6 sockets, Strength 43) and Flail (max 5 sockets, Strength 41 / Dexterity 35) both work. For a weapon-swap shout stick, look at Battle Command 2-6 / Battle Orders 1-6 / Battle Cry 1-4 only. Enhanced Damage 200-240 and Increased Attack Speed 40 are not cast damage.

If the caster already uses a Spirit shield, hunting FCR on the weapon is less necessary. Put skills (or Spirit / Heart of the Oak) on the weapon, and make Faster Cast Rate on shield, gloves, amulet, and rings. That split matches the affix gates.

6. What to buy

① Magic Crystal Sword / Flail — Paladin caster

• Buy: Combat Skills +3 (magic), or Paladin Skills +2
• Skip: Enhanced Damage, Increased Attack Speed, Attack Rating, Crushing Blow
• Do not expect on this base: FCR, mana suffixes, Blessed Hammer +3 and other individual skills

② White Crystal Sword — Spirit

• Pick up a 0-socket in Normal The Secret Cow Level, Larzuk to 4 sockets. Same as the existing Spirit sword guide.
• Superior and ethereal barely help a caster Spirit.

③ White Flail — Heart of the Oak or Call to Arms

• 4 sockets → Heart of the Oak, 5 sockets → Call to Arms.
• If Dexterity 35 is painful, Call to Arms is easier on a Crystal Sword.

④ Scepter / wand / orb / staff — here the extra mods matter

• Individual skills (StaffMods) + class/tab skills + FCR/mana can stack on one weapon.
• “Just look at skills” does not apply here.

Short version

When you pick a Crystal Sword or Flail in the trade window, check the skill numbers first. High Enhanced Damage is not a reason to pay more. On a scepter or orb, if skills and FCR stack, that combination is what you price.
