hm… ideally, if you want to focus on pets, you should go all in on pets and spec out of player damage. summoner playstyle heavily prioritizes focusing on pets alone for damage while the player supports them with buffs and heals while debuffing the enemy.
However, if you really wish to keep the hybrid playstyle, this might be worth looking into even though it is a Warder instead of a Ritualist - [1.1.9.1] Beginner's Hybrid Pet Warder - The Mogdrogen Cleaver - Blue Set - SR75
I am not really experienced with the hybrid playstyle. But, hopefully someone else might be able to help you with that.
