God of War II

Barbarian King
Keep your distance. Roll to avoid ranged attacks. When he summons zombies, kill them first, he will only do so three times.

Euryale
Euryale is the sister of Medusa, and is a big fat gorgon.

Phase 1
 * counter all attacks except vertical tail attack
 * headbutts are fast - be ready to block
 * round tail slash is sometimes followed by unblockable vertical tail attack, roll to avoid
 * use vertical attacks (square)
 * use magic

Phase 2 (climbed onto pillar)
 * attack tail (just hit the pillar)
 * roll to avoid petrifying wave
 * jump to avoid jumping attack

Phase 3 (crawling and hammering with hands)
 * activate Rage of the Titans and go nuts
 * use remaining magic
 * play like phase 1, except roll to avoid hammerings
