There's errata for the missing attack info for Legion of Sentinels, which I happen to have (was gonna use it for 'flanking buddies' for a rogue in another campaign). Their attack mod is your CL and their damage is like that of a longsword, 1d8/19-20 slashing, with a +1 / 3 CL bonus.<br/><br/><br/><br/><br/>Legion of Sentinels (pg 116-117 PHBII)<br/>Illusion (Shadow)<br/>Level: Beguiler 3, sorcerer/wizard 3<br/>Components: V, S, M<br/>Casting Time: 1 Standard Action<br/>Range: Close (25ft. +5ft./2 levels)<br/>Area: 10ft. radius emenation centered on a point in space<br/>Duration: 1 round/level<br/>Saving Throw: None<br/>Spell Resistance: None<br/><br/>A phalanx of spectral swordfighters appears. Their blades drawn, and they stand ready to strike.<br/><br/>A ghostly, incorporeal swordfighter appears in each square covered by the spell's area. A swordfighter can share a space with another creature or object. Each swordfighter threatens the squares adjacent to it and can make one attack of opportunity per round. The swordfighters do not hinder movement, block terrain, or block line of effect. They can flank an opponent with each other and with your allies.<br/>Each swordfighter has hit points equal to twice your caster level and an Armor Class of 25. It makes saving throws or checks with a bonus equal to your caster level.<br/>Material Component: A pewter swordfighter miniature figurine.<br/><br/><br/><br/>Page 116 – Legion of Sentinels<br/>[Omission]<br/>Should include the following text at the end of its<br/>description: “The swordsmen’s attacks are at a<br/>bonus equal to your caster level, they threaten<br/>critical hits on a 19 or 20, and they deal 1d8 points<br/>of slashing damage with a +1 bonus per three caster<br/>levels (max +5). They only make attacks of<br/>opportunity, and their weapon damage is slashing<br/>and is affected by damage reduction.”
