===Mercurial Assassin===
Restricted to [[dragonborn]] who are trained in Bluff or Stealth, making them prime agents to become freaky liquid-metal dragon-men. ''Mercurial Action'' lets an AP give a free move action while ''Quicksilver Speed'' gives +1 to speed and +3 to stealth.  ''Fluid Shape'' forces anyone making an opportunity attack reroll the hit and take the lowest. Fluid Counterattack is an interrupt that shifts the liquid-dragon around to make a counter. Mercurial Disguise is a classic T-1000 type "Turn into someone else" trick and Streaking Mercury coats a weapon in poison to hurt one guy while blinding another guy within range.
Both these attacks key off Dex, so a very obvious route is to be a rogue, who fits both without much effort, as could a bard.
