I’m having trouble defeating the Sentinel with my Ritualist, so I’m looking for advice from the community. I know (or I think I know 
) that I need to keep pulling him out of the green goo on the ground, but how do I get my pets to move out of that?
bind the Pet Attack command to a button and push that every couple seconds. It’ll force them to move and attack the target. I usually keep it bound to LMB so my pets move and attack where I move. Just keep your A key handy in case you need to move out of the way of something without making your pets attack something else.
Thank you, Yawgmoth. I think I understand what you’re suggesting, but I also think I need a little practice with that technique. I’ve lost enough XP tonight; I’ll try again when I’m feeling bolder. 
Also, don’t forget the sentinals green AoE attack takes control of your pets for 3 seconds if it hits them. This can potentially kill you with your own pets, so you’ll also need to pull out your pets when he starts casting it.
Whoa, that’s definitely news to me. Thanks for the tip, Shenhulibu!
