Warped terrorbirds are the result of Glouphrie's experimentation with the Anima Mundi. Once terrorbirds, these mutants are stronger and used for guarding the city of Arposandra. These monsters are weak to melee, most notably slash weapons such as the abyssal whip and chaotic longsword. It is worth noting that the terrorbird's ranged attack is sound-based, so ear protection could prove useful. In other words, using Earmuffs, Masked earmuffs, Slayer helmet or a Full slayer helmet reduces their ranged attacks' maximum hit to 20. This ranged attack will hit twice, so players can be hit up to 40, though this is very unlikely. It is best to know where to find the least amount of terrorbirds as multiple terrorbirds can hit up to 100 in succession. Their maximum melee hit remains the same, however
