Bone Offering is an offering spell that consumes one or more corpses, temporarily granting the player's minions a chance to block attacks and spells, and life regeneration if they have blocked recently.

Skill functions and interactions

The skill consumes a corpse and up to 4 additional corpses around it. Each additional corpse extends the base duration of the skill by 1 second, making the maximum achievable base duration 9 seconds.

Each player may only have one offering active at any time. Casting an Offering skill while one is already active will cancel the older one.
