Aghanim's Shard on Pos 5 Support: Should you buy it early or prioritize defensive items (Force/Glimmer)?

Options

• Always get defensive items first—Glimmer/Force saves team cores.
• Shard rush is correct if the hero Shard unlocks game-changing teamfight mechanics.
• Wait for Tormentor or 30+ minutes unless Shard is hero-defining.
