Offering Skills target an active Skeleton Minion to create an Offering Spike. Offering Spikes grant various Buffs to you or your Minions, and can even directly damage Enemies. Offering Skills are themselves damageable Minions and their Buffs are lost if they die.
Supports Offering Skills. Supported Skills have increased Buff effect and deal more damage, but will target an additional skeletal Minion when cast. If there is not an additional skeletal Minion to target, no damage or Buff effect will be granted.
