As a Beastmaster 3 / Wizard 3, I want to use Speak with Animals to enable my using the Suggestion spell on my beast companion, for the purpose of issuing to her a two-sentence set of "marching orders".
My motivation is so that I don't have to use up my Action each round just to have the beast repeat the Attack or Help action when there is a consistent, repetitive pattern of actions I desire.
A couple of illustrative cases for my intended use of Suggestion with my animal companion are:
"Doggedly attack anyone not in our group who enters this clearing. But if you get badly hurt, disengage and hide."
"Flank whomever I'm attacking and distract them, to help my attacks. But if you get badly hurt, disengage and move behind me."
Will these sorts of applications of Suggestion work for me, in principle, with my own bonded beast companion, according to the rules-as-written? (And if so, can my bonded animal companion automatically fail its save for Suggestion?)
