The sapphire glacialis is a butterfly that players can capture with the Hunter skill at level 25 or above, granting 34 Hunter experience. A good place to catch them is on the second level of the Rellekka Hunter area, near the stairs. There are two spawns close to each other with small wander distances.
Players can find sapphire glacialis at the Rellekka Hunter area, north of Rellekka. When used on a player, it boost the target’s Defence. As usual, it requires a butterfly net and butterfly jar to catch, both of which can be bought at any Hunter store.
After catching a sapphire glacialis, players can use it on another player to increase the other player’s Defence level.
Sapphire glacialis butterflies are often mistaken for the more popular snowy knights because they look similar and are found in the same area and can sometimes be difficult to see due to the colour of the ground.
