Leveling
Giants have good adventures
At 5 explorer, go to pick up the task of digging hedgehog, They are to the left of Vales where there is a snowstorm. When you are using a regular L-rod, it will say that something is buried but you need a different kind of tool to retrieve it.
keep on doing this quest until 20 .it takes some time and patience. Generally speaking, dug enough 8 hours (three open) can reach 20 explorers.
Adventure ten when receiving claw mission, this is the most difficult task. Actually, they're southwest of Vales, Northwest of Silva Forest, at the large rock.
Expedition 15's mission is easy to do
Continue to do hedgehogs until 20.
20 is a paradise for the Giants, then upgrade mission. Then picking the squama mission. This is the upgrade mission for 20 explore. You can make much money here.
weapon/skill(from mabi world wiki)
Two-handed weapons for humans are single-handed for giants; they can be used with shields.
Cannot equip human and elf armor, except for some helmets. They instead wear their own giant robes and giant armor.
Giants have unique weapons only they may use: Giant swords, knuckle weapons, and giant mallets.
Defense skill adds more Defense than with the other races, Counterattack deals more damage
Giants can't wield a bow; instead, they can throw javelins as their only long-range weapon.
Giants Windmill radius is much larger then a humans or elfs windmill radius of the same rank.
