Hydra sorces are useless especially if you put only 5 pts into it. Most melee/missle chars can out run the hydras fireballs, and sorces teleport around them. I can honestly say I've never seen a good hydra sorce. Especially since most of em put 5 hydras around town and expect you to run through them. You want a good sorce? Make a TS/orb sorce. Orb kills people using absorb and ts kills zons in 1-3 hits MOST OF THE TIME.
