Mana cost

Mana cost refers to the amount of mana spent to perform a certain skill once.

Mechanics

Skills generally have a base mana cost which is modified by mana multipliers on linked support gems. The rate of mana use is also affected by cast speed, attack speed, and other speed modifiers such as temporal chains, chills, and Suppressing Fire.

Blood Magic makes character spend life instead of mana on skills.

Mana multipliers on gems and passives are multiplicative. Elreon mod jewelry applies to the mana cost after all multiplication.
