Three of the sirines appeared suddenly, bodies jarred and vibrating and nearly falling over, looking far from the agile things they'd been moments before.<br/><br/>"Music to my ears!" Aria cheered, seeming much emboldened. Her left arm slid up her side, drawing the bow into it. She fired almost point-blank at the two nearest sirines, eager to use their helplessness to aim just where she pleased. The force arrows skewering their pale aquamarine-skinned throats whether the archer was material or ethereal when she shot them; they fell back, skewed twice apiece, bleeding indigo-colored blood onto the cobbles. Aria leaped up with her wing-cloak spreading, nearing the other sirines.<br/><br/><br/><br/>Outstanding tactic, for the reasons you surmised: 1. fey and rogues do have weak Fort saves (fey HD are like bards, poor Fort and good Reflex/Will) 2. hits foes you can't see (single- or multi-target spells  require line of sight) and on every side of you, and also 3. paralysis and other 'helpless' statuses foil (Improved) Uncanny Dodge, letting Aria sneak attack things she wouldn't normally be able to even if she could see them, like with Kass stunned the babau demon. Also most of fey and rogues' AC usually comes from their Dex rather than (natural) armor, and being helpless gives you an effective Dex of 0.<br/><br/>I'm not completely sure if paralysis foils their Hide in Plain Sight when already hidden, but I think it does, since it's a part of movement.<br/><br/>3 of the 4 sirines (all except third from west) are paralyzed.<br/><br/>Aria: draw bow and start attacking from westmost revealed sirine<br/>mods 30/25/20/15 with +4 bonus for attacking helpless foes,<br/>rolls Result: 4, 19, 10, 17,<br/>hit dmg 5+64<br/>hit dmg 6+70 slain<br/>hit dmg 4+68<br/>hit dmg 6+67 slain<br/>Aria takes 5' se and up (i.e. fles up 5')<br/><br/>Unparalyzed sirine:<br/>spring attacks Kass again, successfully hiding / moving silently before and after<br/>atk 19 dmg 4 hp + 2  Int<br/><br/>S' = paralyzed sirine (still paralyzed)<br/>S = attacking sirine (before she moved after attacking)<br/>Aria at altitude 5'<br/><br/><span class="bbc_font" style="font-family: courier;"><br/><br/>__________________________<br/>. . . . . . . .
