Availability Have a character with 100 skill points in Spear
Requested by Lance
Fulfilled to Lance
Reward Clear Spear Theory book.
Detail Defeat groups of 2 or more Gloomy gastropogs using the Multithrust spear ability. Do this 5 times.
Hint for solution Gloomy gastropogs can be found in the Gittish Empire. They don't always appear in groups, so you will have to do some fighting. Have your most powerful attacker attempt the Multithrust. Make sure there are no other enemies left since you cannot control which monsters the attack strikes. Considering casting [[[omph]] to help the attacking character.
