Great item for support and invisible carries late game better then dust for free slot, and allow you to attack all heroes effected by swarm and effected by Geminate.

Strong dispel with spell immunity is one of the best shards upgrades allow target or self for not being disabled after Press of Attack and is great with AOE talent 25.

It doesn't seems it has much debuff duration but one of best upgrades against Illusions heroes right like PL, Naga and CK.

Pudge was worst hero in every position last years and he got several buffs and shard was indirect buff for him, as support allow you to save an ally from the strogest disables in the game like Blackhole, Chrono or Legion duel and healing them that they can ready to fight again in seconds.
