Mana

When a spell orb is created, a certain quantity of mana is allocated to it. This mana is taken from the player's mana pool. If the player's mana pool contains insufficient mana, the spell will fail to cast. Once the assigned mana is removed from the player, it is added to the spell's mana pool for use by the spell. Player mana refills at approximately 10 mana per second.

Mana Consumption
An idle spell orb will consume approximately 1 mana per second from its supply. This means that an spell assigned 5 mana and has no custom behavior will last about 5 seconds before fizzling out.

Performing actions with a spell will cause its mana pool to deplete more quickly. Creating an elastic connection to an object, for example, increases mana consumption by approximately 1 mana per second
