Looking through the official release, I see the Unseelie sprites can actually be invisible until they attack! They also use a sleep poison on their weapons! On a side note, the play-testers are not listed yet. 1e/2e combat info: Unseelie can become invisible at will, they use this ability to stalk, terrorize, and ambush opponents. The mere sight of an Unseelie Sprite is horrific to ordinary people and has the effect of a fear spell on all observers. Unseelie Sprites fight with tiny weapons (swords cause 1d2 points of damage, while bows cause only 1 point of damage). These weapons are often treated with sleep poison, (those hit must save vs. spell or fall asleep for 2d4 hours). Victims often wake, finding themselves bound and being tormented by dozens of wicked Unseelie Sprites, who derive great amusement from the pain and suffering of others. Unseelie Sprites also occasionally ride bats or stirges as battle mounts, attacking with small lances (1d4 points of damage) that are sometimes treated with sleep poison. Each Unseelie Sprite can cast one spell, once per day. This spell can be of any level but is fixed and doesn’t change from day to day. Most are damaging and painful, such as magic missile, lightning bolt, cloudkill, or monster summoning. Each individual Unseelie has a 25% magic resistance. When more than one Unseelie gather a signal location, they influence the weave though. For every Unseelie Sprite in a 10’ radius, all within range receive a +1% bonus to their magic resistance. Example, if 5 Unseelie were in melee range of your party’s fighter, each of those 5 Unseelie would have a magic resistance of 29% (25%+1%+1%+1%+1%).
