Prot is shortened for Protection, so a Prot Monk is logically a Monk that
utilizes and specializes in Protection Prayers. Most Prot Monks will usually
bring the basic essential skills, such as Aegis, Guardian, Shielding Hands,
Protective Spirit, and other low-cost, spammable skills.

For those that don’t know, Protection Prayers reduce the damage done to target
allies and even helps in deflecting and blocking some of these attacks.
Protection Monks are highly looked upon because of their ability to prevent
damage and block attacks with their skills. Protection Monks are also very
useful in places like the Underworld where monsters deal way too much damage
for it to be manageable.
