Trolks are massive stone creatures bearing a stone shield and club mainly found in the Cirromon Caverns and one at the The Sorrowing Meadow. Trolks are also a boss stage when Bopo is stopped right outside of Mudpot. The only way to damage them is to stun them with parry, as Ahrah shows when the first one is encountered.
Trolks can only be damaged after they have been parryed, once parryed Trolks will be stunned for a few seconds so the player can deal some damage to them.
Players can also take advantage of the Trolk's slow speed for a chance to escape if unprepared.
