Question on Sai

[tricktroller]

Ok Folks of the PLayground,

So I have a question about the Sai.

A light Sai gives a +4 bonus to disarm attempts but also gets a -4 for being a light weapon.

However if you use a large Sai it becomes one handed and gives you a -2 to wield it thus giving you +8 to disarm for an actual +6 to disarm.

If you wield a huge one it gives you a -4 to hit but a +16 to disarm for a total of +12 to disarm checks

Is my math right?

+4 per size category medium +0 large +4 huge +8

-4 for light +o for medium +4 for two handed

+4 from sai

The size bonus comes from the size of the wielder, not the weapon. It would be best to use a large sai and wield it two handed (you can choose to wield a one handed weapon 2 handed so long as it isn't light)

Also the -2 from the size penalty applies to the attack roll. It says nothing about the disarm attempt.

+4 from sai, +4 from two handed, +8 total.

Also the -2 from the size penalty applies to the attack roll. It says nothing about the disarm attempt.Disarm is an opposed attack roll.

So, +4 from sai, +4 from two-handed weapon, -4 from weapon two categories too large, adds to +4 to disarm, just like a two-handed weapon of appropriate size.

[Edit]: Yeah, Large sai two-handed would be better, with just -2 penalty you'd end with +6 to disarm (matching ranseur).

[Fouredged Sword]

My bad, thought it was like trip. Special actions always confuse me.

Still, you are better off using one sized larger in two hands. You can get +6 that way.

Wait, didn't they throw out the "Large Light weapon = One-handed Medium weapon" with 3.0?

IIRC in 3.5 a Larger Sai is an oversized Light weapon.

Wait, didn't they throw out the "Large Light weapon = One-handed Medium weapon" with 3.0?Yes and no. You get the penalty for wielding an inappropriately sized weapon, but the "handedness" also changes (so you can't, for example, wield a Large greatsword if you're medium, and require two hands to wield a Large longsword).

[OldTrees1]

Yes and no. You get the penalty for wielding an inappropriately sized weapon, but the "handedness" also changes (so you can't, for example, wield a Large greatsword if you're medium, and require two hands to wield a Large longsword).

Source? (curious)

A weapon’s size category isn’t the same as its size as an object. Instead, a weapon’s size category is keyed to the size of the intended wielder. In general, a light weapon is an object two size categories smaller than the wielder, a one-handed weapon is an object one size category smaller than the wielder, and a two-handed weapon is an object of the same size category as the wielder.

Inappropriately Sized Weapons
A creature can’t make optimum use of a weapon that isn’t properly sized for it. A cumulative -2 penalty applies on attack rolls for each size category of difference between the size of its intended wielder and the size of its actual wielder. If the creature isn’t proficient with the weapon a -4 nonproficiency penalty also applies.

The measure of how much effort it takes to use a weapon (whether the weapon is designated as a light, one-handed, or two-handed weapon for a particular wielder) is altered by one step for each size category of difference between the wielder’s size and the size of the creature for which the weapon was designed. If a weapon’s designation would be changed to something other than light, one-handed, or two-handed by this alteration, the creature can’t wield the weapon at all.

Mmn, tricktroller pasted the text of SRD's Weapon Size entry (http://www.d20srd.org/srd/equipment/weapons.htm#weaponSize). That's indeed the source, though I can dig up the PHB page number if you want, and RC has the relevant stuff on page 151 (I remember the page number since it also includes the passage about inappropriately sized reach weapons that comes up quite often).

[tricktroller]

Which book is SC?

[Greenish]

Spell Compendium. I meant to say RC (for Rules Compendium), though. :smallredface:

[tricktroller]

Doh! I didn't think of spell compendium since we were talking about weapon sizes lol.

Didn't realize they had clarified reach from different sizes finally.
