Returning looking for non-primary pet attack items???

Hi all,

Old timer trying to get grip on things again.
What I am looking for are any clickie items that bring forth temporary combat pets?
Swarm pets? Controllable pets?
If I recall correctly, before I left game at Sentinel's Fate, there were a wide selection of tinkered swarm pets, an attack "hawk" item (can't remember item name), a staff that summoned a sentinel.
Are there any I am missing or other suggestions?

Any helpful responses GREATLY appreciated
