eye of kilrogg refreshes abilities
It functions just like resummoning pet normally with minor differences
Pros: 100 mp vs 1200 mp, doesn't use shard, doesn't stun pet, takes 5 sec instead of 6
Cons: pet loses buffs (like a regular summon), and if pet dies while you are doing this, you don't get a new pet
You can also combine this with the "cast while moving" trick
