Terra Cavern
Cobras start to appear in the area around Elfheim, and while they deal little damage and are easy to take out, they are Poisonous, so they can drain your resources if they get a few lucky hits in. Take them out quickly to avoid the Poison, and be thankful something more dangerous didn't appear. When they appear in large groups in the Terra Cavern, it may be prudent to use a tier-2 Spell to take them all out in one shot.

Anacondas are strange foes that appear towards the middle of the game but pose no significant threat. They deal decent damage, but are easy to kill, and they aren't Poisonous. The main threat is that, unlike most other Monsters, they have a reasonable chance of connecting with a critical hit. Even so, when you run into these in the Terra Cavern, there aren't many encounters you'd rather see.

Sea Snakes have a good number of HP, but low Defense and Attack. In mixed groups, Sea Scorpions are a bigger threat. Sea Snakes make good targets for Masters due to their low Defense, and Bolt2 can soften up large groups of them. Liberal use of the Gauntlets is highly recommended.

ASPS are easier to kill than some Monsters in the ElfLand Area, but their attacks can inflict Poison. You should be able to take them out with simple physical attacks, but make sure you have PURE Potions on hand.
