Ba'al v; Urchin

Ba'al v; Urchin is a bug boss in Bravely Second that is encountered in the Ba'al crater in chapter 1 and optionally re-ecnountered in Fort Lune at the levels of 18 and 50. Urchin is a spider like creature with eight metallic legs that constantly move around and a black body with glowing red markings. Its back has long spikes with constantly changing patterns inside. The head is covered with blue glowing eyes whose glow changes from great to tiny.

Battle
Urchin uses attacks such as the dark based physical attack cloudy day which damages all characters and can cause blind or sunny day to create a shadow of one of the characters as an additional enemy and make it cast dark on one character until that character is KOd or the shadow is defeated. It also uses downpour to unleash four non-elemental attacks that target random enemies (not affected by reflect). The Fort Lune version can also use rainfall to prevent all damage below 9999 from damaging it until it uses downpour again.

Strategy
A good way to win and survive is to make a bishop use holy night on the entire party and default until one has the maximum amount of brave points in order to reduce the amount of time when the boss can deal heavy damage with downpour and lessen the amount of mana the bishop will spend on healing. Using combos of special attacks and attacks from physical classes such as thief when possible can be used to damage the boss as they are more effective than the elemental attacks of classes such as wizard. The weakest unit should have the freelancer class/subclass and use Halfsies and eye drops to remove blindness to save on items once again lessen the mana spent by the bishop but do so only when the physical units are about to attack as urchin can use cloudy day again and force you to spend unneccesary mana and items. When the shadow appears, it is best to defeat it as quickly as possible to remove the trouble by for example using the wizard attacks as they will damage urchin as well.
