3- Rugala grows larger and spins at you like Skeletron, and his Defense is reduced to 25 while executing this move. It has the piercing effect, and will inflict 2 random debuffs for 7.7 seconds each. It will also do 45 damage.

4- Rugala instantly kills you if the battle has lasted 1 hour, so if you are lucky enough to keep the fight going that long, he ends the fun:(

5- Rugala explodes, making 9's appear and cover the screen, making it look like you were dealt 999999999999999999999 (and so on), but it really only does 200 damage if you have no defense.

6- Rugala steals all of your buffs and puts them on himself, each with a duration of 5 minutes. He only does this when he reaches half health. Also, he heals himself to 75,000 HP and attacks more frequently. Finally, his defense increases to 150.

7- When you kill Rugala, he explodes, dealing 99999 damage, but only in a very, very small radius. Therefore, it is advisable to have the last couple of hits with a ranged weapon.
