The Obsidian Boulder is a foe and a summon in Epic Battle Fantasy 5. It is a member of the Boulders enemy group. It is primarily found in Redpine Town and The Rapture

Appearance

The Obsidian Boulder, as the name implies, is made of obsidian stone with glowing orange cracks on its sides and arms. It has orange gems forming its eyes and mouth and a larger orange crystal embedded in the top of its head. The orange gems are presumably made of Ruby, as is the large crystal it uses in battle.

For some of its attacks, the Obsidian Boulder uses a big orange crystal modeled after a 20-sided die . According to the bestiary, this stems from its love of playing Dungeons and Dragons (a popular tabletop RPG), but the veracity of this claim remains uncertain.

Overview

The Obsidian Boulder's main damage output comes from its "D20" attacks, which have a staggering 180% Randomness Factor - for comparison, that's eighteen times higher than the average attack. This gives its boulder attacks a chance to wipe out even a fully-healed and buffed party member's HP; on the other hand, they could cause laughably pitiful damage instead. While hoping for the best may work fine, increasing Fire resistance renders the "D20" a non-issue; in this case, it may also be helpful to inflict Berserk on the Obsidian Boulder, which forces it to use its boulder attacks exclusively. Conversely, Syphon will prevent the foe from using its boulder at all, limiting it to headbutts and arm swings.

Aside from the unique randomness, the Obsidian Boulder has the ability to apply a few status effects; fortunately, these are fairly minor ones with a low infliction chance. While the odds of applying status goes up on harder difficulties, there is nothing more dangerous than Dry or Stagger, potentially strengthening the foes but unlikely to do anything deadly on its own. The potential Defence debuff from the Fire Crystals is more concerning, as the more powerful foes in the area have heavy physical attacks.

Defensively speaking, the Obsidian Boulder has a small selection of resistances and a couple weaknesses. It absorbs Fire, and resists not only Earth and Bio but also Dark. On the flip side, it is weak to Holy, Bomb and especially Water. In terms of statuses, they are completely immune to Poison and Virus, as well as resisting Stun, Death and Doom. To get rid of an Obsidian Boulder, it's best to use one or two high-powered Water attacks, such as Typhoon or Aqua Volley.
