[2019] Need help. Can't get beat these 2 guys on Grandmaster. I just can't, 2 hours spent and still can't. Any tips?

While this might not be something you'd like to read, it is possibly the safest.

Things do get easier as Cal grows through his adventure. You will need to return to some locations as you unlock more abilities and tactics to take on these fine folk. It can be done in lower difficulties, but some you may just need to return later on - when it comes to higher difficulties.

Rock on!!!
The force is strong with this one!
