Re: freedom of movement: true, but by that time you just cast Greater Dispel on them. Or, being a Wizard, you seriously say "Okay I'm using a new shtick all of a sudden." and just spam SoD spells, or the "No save, just die" combos or whatever.<br/><br/>I'm not entirely sure the hydra is better than the standard rogue: the rogue has a full BAB (because they have a wand of "I have full BAB because I'm a cleric", or for that matter because they just prepare and cast the spell, because rogues use candles of invocation to cast spells like clerics) and Perfect TWF (bonus feat as the level 10 ability). They also have rapid shot and haste. So they have 5 attacks at level 6, 7 attacks at level 11, and are permanently hasted by 11th for 10 attacks per round, throwing acid flasks, which are touch attacks (ie they always hit). As opposed to the bite attacks of the hydra. Now, it can probably have more attacks - eleven heads means it's straight up making more attacks, but if you want a good chance of hitting, you'll need to cast wraithstrike every round, and that means you can't cast the "I can crit undead/constructs/plants" spells.<br/><br/>I suppose it all depends on the ACs of your enemies, and how crit-immune they are.
