Black Hole

Black Hole is a somewhat uncommon projectile Spell which summons a dark orb that travels slowly, attracting objects and consuming any terrain in its path. Despite its similarity to Giga Black Hole, this more contained version does no damage to enemies or the player.

It also comes as a variant with an expiration / death trigger, which behaves the same way, but costs 20 additional mana and will cast the next spell when the black hole expires. This can be used to "chain" black holes together, to create longer tunnels, in the absence of a more convenient modifier like Speed Up.

Tips

 * Can spawn in wands that do not have enough max mana to cast it, rendering them useless until reaching the Holy Mountain unless you have the Tinker with Wands Everywhere Perk.
 * Spell modifiers such as Speed Up and Light Shot can greatly increase the range of Black Hole, though it will still not go past your currently loaded game chunks.
 * The Black Hole is one of the few spells than can dig through both Extremely Dense Rock and Cursed Rock.
 * The Projectile Repulsion Sector perk greatly accelerates Black Hole, and in turn the range it covers during its duration.
 * The attraction effect will draw in anything affected by gravity that comes near. This includes projectiles, gold nuggets, items and potions. Since potions are fragile they're more than likely to get smashed in the process, so take care.
 * It will not be made unlimited by the Unlimited Spells perk, but can be manipulated to cast without remaining charges using greek letter spells, like Gamma.
