HYDRAS make three powerful attacks that can deal serious damage to lightly-armored characters. SLOW is an good defense. HYDRAS have a lot of HP but only middling Absorb, so physical attacks are effective. They lack the resistances of other River creatures, and either FIR3 or ICE2 will deal significant damage.

R.HYDRAS are a similar threat to HYDRAS physically, but their CREMATE ability is nearly as powerful as FIR2. AFIR probably isn't necessary against just one R.HYDRA. A physical assault augmented with ICE will make short work of them.

Hydras make three powerful attacks that can deal serious damage to lightly-armored characters. They have a lot of HP but not a huge amount of defense, so taking them out won't be all that difficult. They are Dragons, so the Wyrmkiller is particularly effective against them, but at this point you should have normal Weapons that are just as good. Hydras are a bigger threat than Ochus, but if they appear with Crocodiles, it may be best to take them all out quickly with magic.
